Heavy Duty Roller Tables

Chapter One: What are roller tables, how do they work, and what considerations should be taken into account when selecting them?

What Roller Tables Are

A roller table is a compact, rigid linear guide device featuring an integrated cross-roller guide. It is commonly driven by electrical or mechanical systems, facilitating the movement of heavy loads. Roller tables, often referred to as motorized linear slides with precision rail sets, support heavy loads with minimal friction. Unlike standard ball bearings, roller tables utilize crossed roller bearings to achieve precise linear motion, low friction, and excellent load-support rigidity. They offer a highly accurate linear guiding mechanism and are easily installed with bolts, consisting of a stationary base and a movable carriage.

Roller tables have roller slides with single or many axes, tables, and shafts to maximize direction and control. The size of the intended usage, the material, the weight capacity, and the degree of mobility all go into the design of roller tables. A roller table can be mounted in various ways for multi-axis linear position and motion in the X, XY, or XYZ configurations. Users can stop the table from sliding using shock absorbers or rubber bumpers and employ stroke adjustments for precise alignment. In addition, air-bearing slides for roller tables can be placed when pressured air is controlled between the platform and the base to reduce system errors.

Roller Table Drive System

Roller tables are machines equipped with mechanical or drive systems that facilitate the movement of heavy weights with ease. They are ideal for applications requiring high precision and low friction, such as optical measuring devices, electronics assembly, and more. Additionally, roller tables are employed in a variety of fields, including industrial automation, fiber optics, semiconductor manufacturing, precision instruments, communications equipment, surface and tool grinders, assembly fixtures, and material handling.

How Roller Tables Work

Roller tables can be operated manually using a micrometer, motor, or a combination of both. They typically use a lead screw supported by cylindrical bearings as the driving mechanism to move the carriage. These devices are designed for straightforward linear motion, featuring a fixed base and a moving carriage. In a motorized linear slide, the screw is attached to the stationary base, while the nut assembly is mounted on the moving carriage. As the screw turns, the nut and carriage move linearly along it. The screw can be rotated manually with a hand wheel or driven by an electric motor, enabling precise and controlled placement along a linear axis.

Alternative driving methods, such as linear motors, pneumatic cylinders, and hydraulic cylinders, may be employed instead of lead screws. For example, in a table with a linear motor, the linear motor moves the carriage directly along the slide. The slides are made up of a base with a secure locking mechanism and a movable platform that one may move manually. Roller tables can support big loads since they have two or more slides. When employing hydraulic and pneumatic cylinders with roller tables, the slide base is where the cylinder body is mounted, and the carriage is where the cylinder rod is attached.

Motor Driven Roller Table Slide

A roller table functions as a linear actuator by converting a motor's rotational motion into linear movement. Unlike conventional electric motors that rotate in a circular motion, linear actuators move forward and backward. Roller tables facilitate the sliding, tilting, and lifting of objects with the push-and-pull motion of their mechanism. They use various linear bearing methods to minimize friction, stick-slip, and energy consumption while ensuring smooth operation. To enhance load stability and prevent slipping, roller tables can be equipped with roller cages. Additionally, shields and covers are often added to protect the sliding base and platform from dust, which could otherwise hinder movement.

Linear Actuator

A roller table consists of a moving carriage attached to a linear base. The carriage contains cylindrical or roller bearings that enable low-friction travel between the platform or table and the linear rails. Cylindrical bearings are commonly used in roller tables due to their low mechanical noise. Designed for precision and high load capacity, roller tables are capable of pushing, pulling, or positioning heavy objects accurately. They are available in various configurations, including crossed linear rails, heavy-duty models, and low-profile designs. Roller tables can have a single axis or multiple axes with shafts and tables, enhancing directionality and control through the use of roller slides.

Roller tables offer smooth and precise linear motion, benefiting a wide range of automated machinery. For example, steel roller table assemblies can achieve a straight-line accuracy of 0.0008 inches per inch of travel, while some aluminum or stainless steel assemblies can reach a remarkable accuracy of 0.0000040 inches per inch of travel. The load capacity of roller tables can range from a few pounds to over 2600 lbs (1180 kg).

Specifications

  • Axes: Single-axis systems move along the X-axis and have just one carriage or saddle. Vertical lift mechanisms, on the other hand, move along the Z-axis. Multi-axis positioning systems are certain stacked or connected units that move along two, typically orthogonal, axes in the X-Y plane. There are also multi-axis units that move along the X-axis and Z-axis. Finally, three-axis systems provide three orthogonal axes of motion consisting of Y-axis linear movement, Z-axis linear movement, and X-axis linear movement. The load can be centered on the top in roller tables, which are often two-axis designs.
  • Mechanism: Very stiff, repeatable slides could need a ball screw drive with a motor, depending on the drive mechanism type. A ball or lead screw and hand wheel better serve applications requiring manual positioning and micrometer positioning. For quick actuation that does not need the accuracy and repeatability of a motor-driven slide, pneumatic and hydraulic drives can be employed.
  • Load, Moment, and Stiffness Capacities: Ratings for load capacity, moment, and stiffness depend on the method of bearing system and slide construction.
    • Load capacity refers to the maximum force that can be applied in a direction to an object where it can still properly function.
    • Moment rating refers to how much force can be applied to an arm before it rotates or bends in a way it was not designed to move.
    • Stiffness is the resistance an item has to a force before it starts to bend.

Additional Specifications to Consider:

  • The bearing or manner system in use is what mostly determines slide accuracy. For example, motion can be made precisely and repeatedly using linear bearings.
  • The whole cycle of the slide from one end to the other is referred to as linear travel.
  • The carriage's top speed along the positioning axis is referred to as its linear speed.

Considerations When Selecting Roller Tables

Materials Used to Make Cages

The rollers in a roller table are enclosed in a cage, which can be made from either plastic or metal, to control their movement. This cage reduces friction by preventing direct roller-to-roller contact and helps to extend the lifespan of the rollers.

Traditional metal cages are secured by tabs on the carriage that fit into notches on the rollers. While this design is cost-effective, it limits how closely the rollers can be positioned, thereby reducing the load-carrying capacity of the crossed roller bearing. Metal cages, particularly those made from stainless steel, are preferred for high-temperature, wash-down, and medical applications due to their resistance to corrosion. They are also better suited for controlled environments such as cleanrooms or vacuum settings, as resins used in cages may off-gas and create undesirable conditions.

In contrast, resin cages allow rollers to be positioned more closely together, increasing the contact area between 30% and 58% compared to metal cages. This configuration can accommodate more rollers per inch and result in up to a 250% increase in load capacity.

Choosing the right roller table depends on the specific application and environment in which it will be used. The type of cage, speed, and material construction should align with the intended use, making it crucial to understand the application requirements before making a selection.

Cage Creep

When selecting a roller table, it is important to consider the potential for cage creep. Cage creep occurs when the cage shifts from its longitudinal center over time, particularly if it floats between the bearing's rails. This issue can be exacerbated in vertical mountings or when the linear bearing operates with partial strokes. Shock and vibration can also contribute to cage creep.

Cage creep can restrict slide motion because an off-center cage may encounter a rail end stop and be forced to slip until it realigns itself during the next full stroke of the bearing. This misalignment can cause damage to the retainer, rollers, and slideway as they skid into the end stop. Additionally, cage creep results in rollers slipping rather than rolling, leading to metal-on-metal friction and increased wear.

Fortunately, many roller tables are equipped with anti-creep mechanisms designed to keep the rollers aligned between the V-grooved slideway rails, preventing the retainers from slipping. This feature allows for the rails to be mounted in any orientation and helps to reduce maintenance costs and downtime.

Allowable Load

The "allowable load" denotes the maximum weight that a roller table can handle while ensuring smooth rolling motion on its contact surface, with minimal elastic deformation of both the raceway and rolling components. For applications requiring high precision and smooth operation, it is essential to operate within this permissible load range to avoid performance issues.

Suppliers

Choosing a supplier with expertise in various roller tables is beneficial. Experienced suppliers can offer valuable advice on selecting the most suitable roller table for specific applications. Additionally, a well-stocked supplier should provide a diverse range of roller tables in different sizes and configurations to meet various needs effectively.

Size Restrictions

Available space is a key factor in selecting between a crossed roller bearing and a recirculating ball bushing. With a recirculating ball bushing, only the bushing moves, so the shaft length only needs to match the required travel distance. Conversely, a crossed roller bearing requires a rail assembly that is twice as long as the travel distance because the two rails move in opposite directions. However, using plastic cages in bearings can reduce the length of the cage needed for a given weight, allowing for a longer stroke length on the rail.

Accuracy

For applications where precision is critical, selecting bearings with a higher load capacity margin is essential. This margin helps compensate for potential deformations in rollers and rails when nearing their load limits, which can affect accuracy. Roller slide tables are often preloaded to ensure high precision and eliminate gaps between rollers and guides, and their mounting surfaces are meticulously machined for flatness and parallelism.

Operating Velocity

When evaluating a roller table, consider its operating velocity, which indicates how much material it can move within a specific timeframe. This factor is crucial for determining the efficiency and suitability of the roller table for your application.

Chapter Two: How Roller Tables are Constructed and Components of Roller Tables

Construction of Roller Tables

Roller tables, also known as linear roller tables or roller slide tables, feature a precision-engineered platform equipped with advanced roller bearings. These bearings are specifically designed to minimize friction between the platform and the linear rails, allowing for smooth linear motion. In modern industrial automation and manufacturing processes, cylindrical roller bearings are commonly used in roller tables due to their exceptionally quiet operation, durability, and ability to handle high loads with low rolling resistance. Roller tables play a crucial role in applications demanding accurate material handling, positioning, and heavy load transport within conveyor systems and automation lines.

Aluminum is a popular choice for constructing roller table components due to its high strength-to-weight ratio, corrosion resistance, and capability of supporting heavy loads while maintaining structural integrity. For applications requiring superior resistance to harsh environments or chemicals, stainless steel roller tables are often preferred. In some lightweight or cost-sensitive designs, engineers may incorporate engineering plastics and polymer end caps to reduce weight and operation noise. Roller tables are highly customizable, with options including different track widths, overall dimensions, load capacities, travel lengths, and degrees of movement flexibility tailored to specific industrial or laboratory automation needs. The choice of material and design features directly impacts the table's performance, reliability, and lifecycle.

Roller tables utilize a variety of bearing mechanisms. Common types include recirculating and non-recirculating linear roller bearings, linear ball bearings, flat-type roller bearings, and precision crossed roller bearings. The incorporation of roller cages or retainer assemblies enhances load stability, accuracy, and prevents roller slippage during high-speed or repetitive motion cycles. Selecting the appropriate bearing type is vital, as each offers distinct advantages in terms of load rating, precision alignment, velocity, and environmental suitability. Roller table configurations can be tailored for vertical, horizontal, or multi-axis linear movement in demanding machine tool and automation equipment.

To ensure reliable performance and extended bearing life, many roller tables and linear slide assemblies are equipped with dust covers, bellows, or shielding options. These protective features prevent particulates, debris, and contaminants from interfering with the rolling mechanism, maintaining smooth operation and precision guidance. Routine maintenance is essential for high-performance roller tables—periodic cleaning, lubrication, and inspection of the slides help maintain accuracy, minimize wear, and maximize service life. Users should follow manufacturer-recommended maintenance schedules and use the correct lubricants to achieve optimal system longevity and reduce downtime in production environments.

Modern roller tables often incorporate innovative technologies such as stud roller mechanisms and resin or polymer retainers. The stud roller system is specifically engineered to eliminate roller cage displacement, allowing for multi-directional movement and precise positioning with minimal backlash. These next-generation mechanisms permit rapid acceleration and deceleration, providing enhanced motion control and extremely quiet operation ideal for precision assembly and semiconductor manufacturing. Advanced designs of R-retainers and precision roller tracks further optimize the efficiency, rigidity, and repeatability of the table's linear motion system, accommodating a wide variety of high-speed automation and robotics applications.

Stud Roller System

Components of Roller Tables

A high-quality roller table is constructed with two linear bearings, a single-piece base, and a single-piece tabletop, forming the foundation for high-precision linear guide systems and industrial automation platforms.

  • The Base or Bed: This structural foundation can be fixed to a machine frame, industrial work cell, or other mounting surfaces and is typically stationary. The base supports the linear slide bearings, servomotors or stepper motors, and any ball screw or linear actuator used for motion control. Bases are typically made of robust materials such as cast iron, carbon steel, or aluminum alloy, selected for vibration damping and dimensional stability.
  • The Carriage or Table: The carriage, or moving platform, attaches to the active part of the linear bearing or automated drive system. It supports spindles, instrumentation, workpieces, or other assemblies requiring precise and repeatable linear movement. Common materials include machined aluminum, steel, or cast iron to ensure rigidity and minimize deflection under heavy loads.
  • Linear Bearings: These bearings, critical to the roller table's performance, may be purchased as precision components or custom engineered and integrated within the slide assembly. Linear bearings provide low-friction, precise motion and are available in a range of load ratings and configurations to suit specific automation, CNC machining, or assembly line applications.
  • Roller Cage: The roller cage or bearing retainer secures the rollers in a precise array during movement, preventing migration or misalignment. It contains the raceway, guiding rollers to maintain even load distribution and smooth rolling contact.
  • The Adjustment Screw or Set Screw: Roller tables often include an integrated adjustment screw or preload setting, which allows technicians to fine-tune the clearance and tension between the carriage and the base. This adjustment enables optimal linear accuracy, reduces play, and controls the stiffness of the system for demanding industrial processes.
  • Carriage Attachment Threaded Hole: Strategically placed, these threaded holes allow secure mounting of fixtures, jigs, process tools, sensors, or robotic end effectors to the moving carriage, enabling seamless integration into automated production systems.
  • Retainer End Cap and Rear End Cap: End caps safeguard the retainer grooves, ensuring that bearings or rollers do not fall out during high-speed operations or transportation, thus maintaining the reliability and safety of the linear motion system.
  • Ball Screws and Lead Screws: Ball screws and lead screws provide precise, repeatable, and efficient linear actuation, translating rotary motion into linear displacement with high accuracy. The screw nut is often fixed to the carriage, while a rotary bearing assembly supports the screw, allowing smooth and controlled motion—crucial for machine tools, pick-and-place robots, and precise positioners.
  • Linear Motors: High-performance linear motors, including servo, stepper, and direct drive variants, are utilized to position the carriage with exceptional speed, high force output, and accuracy. They are commonly used in high-throughput laboratory automation, medical device manufacturing, and semiconductor assembly equipment.
  • Pneumatic or Hydraulic Cylinders: These cylinders, operated by compressed air or hydraulic fluid, deliver powerful, controlled linear motion for applications involving heavy loads, rapid cycling, or cleanroom operations. Pneumatic and hydraulic linear actuators are selected based on the force, speed, and environmental demands of the system.

Choosing the appropriate roller table configuration and components is vital for meeting diverse industrial requirements—ranging from material transport on conveyor systems to high-speed pick-and-place automation, CNC machining centers, and laboratory instrumentation. Roller tables can be supplied in manual or motorized versions, with options for integrated position sensors, limit switches, or feedback encoders for advanced motion control and smart automation integration. When evaluating roller tables, end-users should consider factors such as load capacity, accuracy, travel length, environmental sealing, operational speed, and compatibility with existing automation or robotic systems. Selecting the right supplier or manufacturer is equally important to ensure quality, precision engineering, reliable support, and the availability of replacement parts and expert maintenance services.

    Chapter Three: What are the types of roller table drives, roller table slide bearings, and roller tables?

    Types of Roller Table Drives

    Ball or Lead Screw Drives

    This type of driving system converts rotational motion into precise linear movement. It primarily consists of a screw and a nut. Actuators using ball or lead screws function similarly to power screws. When the screw or nut rotates, it moves the other component linearly. Ball screws are often preferred due to their robust design, high driving force, and minimal backlash.

    Lead Screws

    Rack and Pinion Drives

    This drive mechanism features a pinion connected to a linear gear, converting rotational motion into linear movement. The pinion, driven by a motor, is mounted on the carriage. As the pinion rotates, the carriage travels along the rack. Unlike ball screw and belt drives, the rack system accommodates multiple carriages, as each pinion's rotation operates independently from the others.

    Rack and Pinion Gear

    Linear Motor Drives

    Unlike conventional motors, a linear motor operates with a stator and rotor that are not part of a continuous loop. It functions on principles similar to rotary induction motors, but instead of rotating, the motor generates linear motion. An electromagnet on the carriage creates an electromagnetic force that attracts permanent magnets mounted on the guide rail. This setup produces the thrust force needed for movement. Linear motors offer superior positioning precision compared to traditional drives, as they eliminate intermediate mechanical components, reducing backlash and elastic deformation. Additionally, with fewer moving parts, linear motors require less maintenance and experience less wear.

    Linear Motor

    Pneumatic Systems

    Pneumatic systems utilize piston and cylinder assemblies, where compressed air is supplied to one or both ends of the cylinder. This increases the pressure inside, moving the piston and controlling the extension or contraction of a rod attached to one side of the piston. There are two main types of pneumatic cylinders: single-acting and double-acting. A single-acting cylinder has one inlet port and uses pneumatic power for one stroke, while opposing forces, such as spring tension, are responsible for the return stroke. In contrast, a double-acting cylinder features inlet ports at both ends, allowing pneumatic power to be used for both strokes.

    In the simplest pneumatic actuators, part of the carriage is attached to the end of the rod. This design requires the rod to be twice as long as the stroke length. Alternative coupling mechanisms, such as cables, bands, and magnets, can be used to replace the rod. Pneumatic systems are known for their high speeds and are often used in explosion-proof environments due to the absence of electrical components. However, they lack precision, as the carriage can only move between end positions and cannot stop at intermediate points.

    Pneumatic Driven Table

    Micrometer Drives

    This drive operates on a principle similar to that of a lead screw, but with the precision of a micrometer screw gauge. It typically features a lock nut that allows users to set and lock the desired distance. Once the table reaches this preset distance, it stops automatically.

    Micrometer Drive

    Types of Roller Table Slide Bearings

    Roller tables utilize various types of bearings to facilitate the smooth sliding of the carriage along the base. Some of the common slide bearings used include:

    Needle Roller Bearings

    Needle roller bearings feature a carriage track with a V-shaped profile, forming a 90° angle. This design incorporates rows of cylindrical or needle rollers aligned along both sides of the V-profile, which facilitates the handling of high radial loads in a confined space.

    Needle Linear Bearings

    Flat-Type Roller Bearings

    In flat-type roller bearings, the cylindrical or needle rollers are arranged horizontally within the cage. These rollers are aligned with their axes parallel to the direction of linear movement.

    Flat-Type Roller Bearings

    Ball Bearings

    Ball bearing slides are the most common type of linear slide tables. These slides feature ball bearings within the linear base, offering smooth and accurate motion along a single-axis design. They are known for their self-lubricating properties, which enhance their reliability. The carriage moves along the guide rail via recirculating ball bearings, which continuously circulate within a looped raceway. This design allows the carriage to traverse any length of the guide rail without restriction, and multiple raceways are typically present in recirculating linear bearings.

    Non-recirculating and Recirculating Linear Ball Bearings

    Metal balls are attached to the cage in linear ball bearings that do not recirculate. The track geometry of the mating grooves between the bearing and the guide rail can be either circular or gothic arch.

    Linear Ball Bearing

    Crossed Roller Bearings

    Crossed roller bearings provide enhanced precision, rigidity, and load-bearing capabilities compared to traditional friction-reducing components such as ball bearings. Unlike ball bearings, crossed roller bearings excel in handling moment loads, radial forces, and tilting loads. By using a single crossed roller bearing instead of multiple ball bearings, space is conserved, leading to reduced material costs. These bearings are ideal for high-precision applications that require smooth and relatively fast linear motion. Crossed roller bearings offer improved control, load capacity, and accuracy, with the rails typically intersecting at a 45° angle between the base and the carriage in roller table systems.

    Crossed Roller Bearings

    Types of Roller Tables

    Heavy-Duty Roller Tables

    Heavy-duty crossed roller tables are designed to handle substantial weight and deliver exceptional precision. They are ideal for lifting heavy items and large cartons. These tables typically offer accuracy levels ranging from 0.0001" to 0.00008" per inch of travel, ensuring robust load-bearing performance.

    These tables often feature an anti-creep system, making them suitable for vertical applications and scenarios involving significant acceleration or deceleration forces. Heavy-duty roller tables are generally driven mechanically to support heavy loads. The image below illustrates a heavy-duty roller table driven by a ball screw, which helps prevent roller cage migration or slippage in high-speed and vertical applications. Additionally, they are equipped with couplings for secure connections, hex-shaft axles for enhanced capacity and strength, and various curve options such as 30°, 45°, 60°, and 90°.

    Heavy Duty Roller Table

    Crossed-Linear Roller Tables

    These roller tables are capable of handling substantial loads while delivering enhanced control and accuracy. They come in various construction materials, including steel and aluminum, with mounting options available in both metric and inch measurements. For applications involving significant acceleration, deceleration, or vertical movement, tables designed to prevent cage creep are recommended. The design of the roller cage and rail effectively mitigates issues like slippage or migration in high-speed and high-vertical settings. Preloaded and factory-ready, these tables utilize crossed roller bearings to provide exceptionally precise linear motion with minimal friction.

    Low-Profile Roller Tables

    Low-profile slide tables designed for high precision often feature adjustable preloading and can be made with either ball bearings or crossed rollers. These tables offer superior linear support and guidance with remarkable repeatability and reduced friction. When comparing tables of similar sizes, crossed roller tables generally support higher loads compared to ball-bearing tables due to their 45-degree angled rollers, which enable them to handle stress from all directions. Pneumatic systems are commonly used to drive these low-profile roller tables.

    Low Profile Pneumatic Roller Table System

    Chapter Four: What are the applications and benefits of roller tables?

    Applications of Roller Tables

    Roller tables are versatile components capable of operating across various speeds and load conditions. Their adaptability makes them suitable for numerous applications, including:

    Robotics

    In robotics, roller tables meet diverse motion requirements, handling both light and heavy loads while performing intricate tasks within compact spaces. They offer the necessary stiffness, smooth motion, and precision in various sizes and configurations to align with different robotic systems.

    Power Tools

    Roller tables provide smooth, accurate linear motion for power tool shafts, enhancing operational precision and efficiency.

    The Medical and Life Sciences

    In medical and laboratory environments, roller tables facilitate the precise positioning and manipulation of small components or instruments. Their accuracy makes them ideal for applications like indexing tables in blood centrifuges.

    Electronics and Semiconductor Manufacturing

    The electronics and semiconductor sectors rely on roller tables for micron-level accuracy in tasks such as pick-and-place operations and silicon wafer handling. These tables can be configured for use in cleanroom environments to maintain stringent cleanliness standards.

    Aerospace and Defense

    In aerospace and defense, roller tables are employed in equipment requiring exact linear motion. Their high load-bearing capacity and precision make them suitable for applications like airline seat adjustment systems.

    Food and Drink

    For food processing, roller tables used in spindles and slicers must offer precision and durability while maintaining cleanliness. Crossed roller tables, when combined with food-grade lubricants, provide the necessary stiffness and load capacity without compromising food safety.

    Benefits of Roller Tables

    • Freedom in Mounting: Roller tables are trustworthy in applications like vertical axes where cage creep may occur.
    • Operation High-Speed and High-Tact: Even for operations at high velocities, cage creep correction is not required.
    • Conserving Energy: There is no need for cage motion remediation even during prolonged operation.
    • Perfect for Micro-Feeding: Because of the linear motion without stick-slip caused by incredibly low frictional resistance, improvements in precise positioning accuracy and corresponding superior feature to micro-feeding command can be anticipated.
    • Simple Installation: The mounting holes are equipped with drilling and female thread to allow for an unrestricted mounting structure. The module type produces high-accuracy linear motion because it combines two internal ways into a single construction.
    • Superior Load Distribution: This device has a roller cage with cylindrical rollers that are alternately orthogonalized between two ways, each of which has two V-shaped surfaces used as track grooves, allowing loads to be received from any direction.
    • Improved Accuracy: Even in high-performance environments, accuracy has improved. Accurate linear motion with no slippage over time is delivered by components that have been precisely machined and matched.
    • Reduced Friction: A roller table experiences less friction due to a rolling mechanism that maintains performance across a broad speed range.
    • Simple Installation: By fastening the product with bolts, the roller guide can be mounted between a pinpoint accuracy table and base to provide a precise linear guide mechanism. Additionally, they have pre-drilled mounting holes that do not require adjusting.
    • Highly Corrosion Resistant: Most models employ plastic, aluminum, or stainless steel for the foundation and the table. They also have stainless steel screws, roller cages, rails, and rollers. These guiding systems have very high corrosion resistance as a result.
    • Large Permissible Load: The roller table can support a heavy load while maintaining a highly rigid linear guide mechanism and a long service life, thanks to the installation of rollers with large rated loads in short pitches.
    • Diverse Use: Because rollers are arranged one after the other orthogonally, the guide system can evenly distribute loads in the four directions used on the table.
