Industry Information

Linear Slides

Linear slides are devices which are used to provide precision motion along linear planes for many different types of automated machinery for the purposes of pushing, pulling or positioning. Using ball bearings, or cylindrical bearings, linear slides are able to move with low friction and energy expenditure.

Some linear slides are motorized such as machine slides, XY tables, roller tables and some dovetail slides which are then able to handle heavy and cumbersome loads. Other slides such as drawer slides, ball bearing slides, telescopic slides and roller slides do not need the addition of a driver engine and rely on hand power, inertia or gravity to move the load through the linear guide. There are many applications in which linear slides are used including: clean room operating systems, robotic assembly machinery, automatic packaging equipment and CNC machining equipment such as drilling and grinding machines. Linear rails are also used in many other diverse industries, such as semiconductor, chemical processing, optical, textile and commercial. While basic linear slides are used to provide motion along a single plain and back and forth in one direction, advanced linear slides, such as positioning stages, XY tables, linear stages and machine slides may be designed and configured to provide movement along multiple axes. These systems are more complicated to manufacture and yet can be used to drastically cut back on operating procedure times.

Typically, linear slides are composed of a stationary base onto which a carriage, or moving platform or component, is attached along a linear rail of bearings. The carriage slides along the bearings from one end of the base to the other with minimal friction, offering a precisely restricted range of movement. This is ideal for many applications such as precision eyeglass assembly, robotic welding, instrumentation and other specialized processes. The precisely controlled automated equipment using linear slides provides an ideal solution to many operating needs for both large and small applications. While some applications rely on inertia or gravity to move the carriage, others are motor driven which further adds to the control of the motion process as the load or equipment can be moved at an exactly desired speed. However, linear slides are designed primarily for precision movement control, not for power. Although linear slide components are used to move thousands of pounds of weight, and ball bearing slides and crossed roller slides are both capable of handling heavy loads, this is done with minimal friction as the bearings provide a sliding mechanism. Therefore, only a relatively small amount of torque is required to move even massive loads. Roller slides tend to absorb less stress from weight as they offer a line of contact, rather than the point contact of a ball bearing.

Cast iron is commonly used to fabricate components of a linear system as it is a durable and strong material which is able to withstand a fair amount of wear and tear which linear systems, especially those designed for heavier load carrying, are susceptible to. Aluminum is another commonly used material as it is able to maintain its shape and structure even under stress. Stainless steel is used as the material for linear systems which are designed to be used in work environments in which humidity and corrosion may be factors. For processes which have prolonged exposure to moisture, corrosion in the linear bearing system would result in system failure. Therefore, stainless steel is used as its corrosion resistant properties combined with its durability make it an ideal material choice. Linear slides are a cost-effective piece of operating machinery and tend to be low maintenance equipment. The bearings used in the linear system are the components that show deterioration soonest as they are the point of contact between the weight of the load and the linear rails. Roller slides tend to absorb less stress from weight as they offer a line of contact, rather than the point contact of a ball bearing. Ball bearings are most susceptible to wear and tear, even those made from cast iron, and will need to be periodically replaced to ensure the optimum running of the linear rail system.

Plant conditions are an important factor to consider when choosing linear systems. Bearing housings should be used to provide a protective barrier between the sensitive bearing systems and the possible contaminants of debris and dust. Covers or other shields should be used where it is possible to attach them to the slide system without interfering in the operations of the sliding mechanism. In machine slides, machine ways are used which are placed in front of the attached carriage to brush or wipe clean the railing before the carriage passes over it. This removes dirt particles which would speed up the rate of wear and tear on the complete system. Dovetail slides may require additional lubrication, but most linear slides should be able to maintain a low-friction, smooth movement without adding further lubrication. Precisely controlled automated equipment is costly and the procedures which use linear slides are often dependent upon accuracy, therefore it is important to maintain optimum working conditions of linear slide systems including regular maintenance and repair when needed.

Different Types of Linear Slides

Linear slides are technically known as linear motion bearings. They are designed for and used in machineries and mechanisms to provide free motion and control the machine's operation. There are motorized bearings or slides that are used for some special systems. Frequently used motorized slides are machine slides, roller tables, and dovetail slides. These motorized slides are run by a drive mechanism, which is powered by electricity (AC or DC power) and sometimes fuel.

The name linear slide comes from the action these mechanisms carry out. Linear slides provide linear motion, which is why they are called linear slides or linear bearings. There are different types of bearings used in a range of industrial process machines. This article, in the following sections, outlines various types of linear slides -

Rolling Element Slides:

Rolling element slides are made from a sleeve-like outer ring, in addition to many rows of balls that are assembled in a set of cages. Earlier, these cages were made from solid metal, but now, these can be a composition of stampings. The key job of these bearings is to render smooth motions, while providing low friction and durability to the mechanism. These slides also offer high rigidity and affordable operation, due to their easy maintenance feature.

Some of the biggest advantages of these slides include: they are stronger than plain bearings, have less chances of contamination, and their speed and motion can be increased by using lubricants.

Ball Bearing Slides:

Ball bearing slides are a type of rolling element slide known for their smooth and accurate motions in a single-axis linear environment. The single-axis is positioned in the linear base that has its own lubrication technique, which automatically increases the speed of the motion whenever needed.

All these innovations are an ideal utility for the manufacturing, electronics, home appliances, and building construction purposes. Ball bearing slides are one the most powerful bearings for these industries, since they are made from aluminum, steel, and sometimes galvanized steel.

Roller slides:

Roller slides are also a type of roller element slide, which are put into the category of non-motorized bearings. These slides are often used for the machines that are run by the inertia or hands. Due to their crisscrossed movement, they are also called crossed roller slides. These slides are used to provide heavy load bearing capability to the mechanism. From the medical to the telecommunication industry, and from construction and automation to vacuum systems and clean rooms, roller slides play an important role in a large number of industrial applications. The best part of roller slides is their versatility. Also, they can be engineered to fit into various applications, as required.

Plain slides:

In their design, plain bearings are very close to roller slides. Since there is no provision of ball bearings, these slides have limited usage. Additionally, they are not as rigid as rolling element slides. Plain slides are also called bushings and are made from metal and plastic materials. These bearings can efficiently run on steel and stainless steel shafts, in addition to the ones that are made from aluminum.

All You Need To Know About Linear Motion Bearings or Linear Slides

Linear slides and linear motion bearings are two names for the same mechanism, used in a large number of industrial applications. These bearings consistent of three main parts, a pad, bushing, and roller system, which carry the load. The load is ideally placed on a rail, the length of which is defined by the actuator. Rails are a simple design element and have a flat surface. In addition, rails can be a perfectly round, polished rod. Sometimes, they can be a complex design, which is typically decided based on the application.

Although linear slides have a prolonged durability, their life majorly depends on the load, speed, and frequency.

Also, there are special purpose linear slides that are commonly used in drawers and work tables that have moving parts. For smooth and noiseless functioning, both the slides and rail need to have a smooth surface.


Bushings are used to create the simplest linear slides. They are innovatively designed cylinders with thin walls. These cylinders are created via the injection molding process, are made from polymers, and used with a set of lubricants to foster the smooth motion. At times, there are bronze metal cylinders that have oil infused in the body. These bronze cylinders rotate and slide around the polished rod.

Linear Guides:

Linear guides are known for carrying and bearing heavy loads. These slides have a re-circulating ball, which is technically referred to as a roller bearing affixed into a rectangular pad. These rectangular pads are often replaced by slide units. In linear motion guides, there can be more than one rail, to support faster and more reliable sliding and bearing of the load.

Ball Spline:

Ball splines are nothing but an advanced design of linear slides that have a cylinder that acts as the sliding unit of the mechanism. The cylinder typically has three to five circuits that help recirculate the balls, ensuring easy and controlled movement. Some linear slide manufacturers also create low maintenance slides, cylinders, and balls - that will help you save on your designing and manufacturing cost.

V Rail:

Sometimes, long-length rails are strategically designed to have a "V" shape to help with space and material management. There is another benefit of these designs, V-shaped rails are less likely to get affected or damaged by dust and other possible pollutants. In addition, these designs do not need a bellow or cover to protect it.

Accessories for linear slides:

A large number of accessories are used by engineers to create effective linear slide rail systems. One such accessory, a wiper, is used for is used for sweeping the rail right before the slide unit. This movement ensures that there is no debris on the rail to impact the performance of the linear sliding system. Sometimes, seals are also used to keep away the dust and dirt from the rail. However, for seals, debris is not consist of dust and particulates, but an excess of lubricants.

How to Find a Reliable Linear Slide Supplier

Linear slides are linear motion bearings that are utilized in the design of a wide variety of applications we see or use in our day to life. The primary job of these utilities is to support effortless, quick, and noiseless movement of a part. Linear slides are present in hundreds of options, depending on the type and size the application.

Linear Slides for Smoothly Working Application

Linear slide is a type of bearing that is designed for enabling free motions in an application. Also known as the linear motion bearing, these slides provide motion to a part in the desired direction. These motion-bearing elements offer accurate support and guidance to the mechanism. In addition to this, these instruments provide low and controlled friction, as well as smooth, accurate motion to applications. Linear slides are used across many industries, including medical, factory automation, machining, packaging, semiconductor, aerospace, printing, automotive, and food production, etc.

Choosing the right linear slide is crucial for smooth and efficient operation. In the following descriptions, are some tips on how to ensure that the linear motion bearing slides are working fine for your application -

Understand the various types:

Linear slides are available in different types, to suit a variety of applications. First, you need to establish which type of linear slide you need for your industrial process machine. Not every slide will be suitable for achieving your desired motion and rotation. Therefore, it becomes necessary to consult a knowledgeable linear slide supplier to find out which type, size, and capacity will be best suited for your exact requirements.

  • Round rail bearing system: Round rail bearing is one of the two types of railing and bushing systems that enable torsional misalignment in the application. These bearings provide a point contact on the inner and outer race. This enables low friction and low load capacity.
  • Profile rail bearing system: This is another type of profile rail bearing system that provides higher accuracy, superior rigor, and better load capacity. Profile rail slides are a superior option over round rail bearings. Additionally, they are compact in design, meaning, these can be used for a number of applications that need higher accuracy, rigor, and load capacity in less space.

Different types of loads:

The load that these linear bearings tolerate varies with the type of application. The various types of loads are: vertical loads, moment loads, dynamic equivalent load, horizontal loads, pitch roll, and yaw. Sometimes, the load can be a combination of all these. At times, the direction and angle of the load can also vary. The intensity of the load also differs in some industrial operations.

Linear slides accuracy:

Linear bearing accuracy is the variation in height and length. For a fluent operation, it is necessary for the slide to achieve the best possible accuracies. For applications that do not have perfect accuracy, having a profile rail bearing system can be a suitable option.

Bearing preload:

To minimize deflection, bearing preload can be used with both round and profile rail bearings. Preloading can provide internal clearance in the bearing. Preloading can be generated by creating an interference between the outer and inner race and fine-tuning the rolling elements.

Linear slides are available in low precision options. These low precisions include sleds, slides, carts, and drawers. Sometimes, these slides are also present in medium precision, such as saw guides and door guides.

Linear Slide Types

  • Ball bearing slides, also referred to as "ball slides," are the most common type of linear slide because of their self-lubricating qualities, which increase their reliability. Ball bearing slides, which perform with a smooth linear motion, typically use four hardened and ground shafts that surround the balls at four different points.
  • Crossed roller slides utilize rollers that crisscross each other and usually move between a group of four semi-flat and parallel rods, which surround them. The design of crossed roller slides allows them to carry up to twice the load of ball bearing slides and to absorb larger impacts.
  • Dovetail slides are used in high load applications that require long travel distances and/or damping. Dovetail slides consist of a saddle or flaring tenon and a fixed base. 
  • Drawer slides are a specific type of linear slide used to mobilize drawers for easier access.
  • Linear guide are used to support and guide the rolling elements, typically rollers or balls, of a linear bearing.
  • Linear rails consists of a smooth, flat base that is used to support and guide the motion of linear bearings.
  • Linear positioners consist of a drive that is attached to a fixed slide base and two extended springs that pull the slide top toward the screw end, against which it is firmly held. As the screw is turned clockwise, it moves the slide top forward along the linear axis, and because of the spring pressure, the screw retracts when turned counter-clockwise, resulting in a smooth linear rotation.
  • Linear stages are reliable single- or multi-axis mechanical systems that position a payload and consist of few components, including a linear motor, bearings, encoder, limit switches, cable carrier and bellows. Linear motor positioning stages move payloads vertically or horizontally without mechanical transmission devices and at varying rates of acceleration and speed.
  • Machine slides are precision products used in CNC machining.
  • Positioning stages are linear slides with the addition of a drive mechanism that allows them to be used to provide both low-friction linear movement and controlled, precision positioning along a linear axis.
  • Precision slides consist of a carrier, a base and ways fitted together with a gib and gib screws, which allow for adjustment to ensure accurate movement. Precision slides are basically motion guides that are used to feed and retract parts, tools or fixtures on all kinds of equipment.
  • Roller slides use perpendicular rollers and have a higher load capacity than ball bearings.
  • Roller tables are the quietest type of bearing table.
  • Rotary stages rotate on an axis, typically positioned in the center, and provide rotary motion used in positioning and moving objects. Rotary stages are utilized to adjust the roll, pitch and yaw of objects, as opposed to linear stages, which position objects in space.
  • Standard slides integrate roller or ball guides to permit the engineering of complete systems easily and with a minimum of assembly time.
  • Telescopic slides are linear motion devices that are capable of compaction and extension as a result of concentric parts that slide inside of each other.
  • XY tables are motorized linear slides, with linear motion based in bearings and driven by a drive mechanism, typically a linear motor.
