Leading Linear Motion Bearing Manufacturers

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. Read More…

Linear Ball Bearings Linear ball bearings are typically composed of an outer assembly with linear rows of spherical bearing elements. These rolling components are used to separate two parts along a straight line in order to facilitate ease of movement.

Bearing systems are typically low maintenance motion device options; however linear motion bearings will require periodical maintenance and/or replacing to ensure the optimum performance of the system.

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

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 to further minimize friction.

Linear Bearings

Linear Bearings

Linear bearings are a type of bearing that "bear" or support the load of the carriage during its single-axis linear movement and provide a low friction sliding surface for the guide rails. In a linear guide, the carriage is the component that travels in a straight line, back and forth, along the length of the guide rail...

Linear Actuators

Linear Actuators

A linear actuator is a means for converting rotational motion into push or pull linear motion, which can be used for lifting, dropping, sliding, or tilting of machines or materials. They provide safe and clean...

Linear Slides

Linear Slides

Linear slides, also referred to as linear guides or linear-motion bearings, are types of bearings that allow smooth and near-frictionless motion in a single axis. Machine tools, robots, actuators, sensors, and other mechanical equipment often require moving components in a straight line in any of the three-dimensional axes...

Ball Bearings

Deep Grove Ball Bearing

Ball bearings are types of rolling-elements bearings that carry loads, reduce friction, and position moving machine parts while facilitating motion. They reduce surface contact and friction across moving planes by...

Ball Screws

Ball Screws

Ball screws are mechanical linear actuators that consist of a screw shaft and a nut that contain a ball that rolls between their matching helical grooves. The primary function of ball screws is to convert rotational motion to linear motion. Ball nuts are used in...
