Linear Motion Bearings Industry Information

Linear Motion Bearings

Linear motion bearings are motion components used to aid in low friction linear motion of loads requiring high accuracy and repeatability in their movement. Due to their accuracy, low cost, and availability, linear motion bearings are used in a variety of industrial applications. Bearing systems are typically low maintenance motion device options. However, linear motion bearings require periodical maintenance and/or replacing to ensure the optimum performance of the system.

Linear Motion Bearing Design

Linear bearings are commonly constructed from materials like steel or aluminum, which provide a strong and durable material able to bear the weight of moving loads without excessive wear and tear. Rolling elements are either ball bearings or roller slides. Ball bearings tend to wear out faster than roller slides, but both are useful in a wide variety of applications.

The load capacities of linear devices can vary greatly according to design and depending on the material used to construct the motion device. Motorized linear slides can be used for heavier loads or extreme precision and are moved by drive mechanisms. Other manually operated slides rely on gravity, inertia, or hand power to move. For heavy load applications, or for long distance applications, the housing system of the linear motion bearings can be strengthened by the addition of support rails or guide wheels either continuously or at intermittent points in order to prevent structural failure along the linear rails.

Linear Motion Bearings Maintenance Considerations

Upkeep for linear motion bearings may include slight railing and positioning adjustments, especially in applications with heavy loads and/or those requiring high precision. For applications in which air-borne debris is a factor, the bearings and assembly shafts may have to be opened and cleaned. Lubricants can also be added to the rail systems to extend the lifespan of the bearings and further minimize friction.

Types of Linear Motion Bearings

There is a wide range of styles of linear motion bearing devices, such as linear air bearings, linear roller bearings, and linear or rotary bearings. Rolling element linear motion bearings, of which linear ball bearings and linear roller bearings are varieties, are far more accurate than sliding contact bearings, so they are among the most commonly used linear motion bearings.

Linear bearing systems can vary in terms of stiffness or intended velocity, as well as in the smoothness of motion. These factors will be adjusted according to the application of the bearing slide. Other factors, such as height and length, rolling element, and material choice can also be changed according to specific needs.
