Essentially, a guide wheel is a ball bearing that has a special shaped outer race. The inner and outer races of ball bearings are a framework with a groove for the balls to rest in. Burke explained ...

The ability to mount and move equipment is essential to any modern manufacturing plant. Many factory and machine setups have doors, cages, containers, and panels that move to allow workers access to ...

Linear bearings are distinguished from radial bearings by their sliding rather than rotary motion. Linear bearings are used in machine tool applications such as sliding doors, 3D printers, and ...

Most linear bearings incorporate ball bearings (usually of metal) to reduce friction between moving parts. Of these designs, most bushings, ball splines, linear guides and slides recirculate balls. As ...

The accuracy of motion systems used in precision automation applications is significantly dependent on top-tier positioning stages and motion controllers. When designing a next-generation machine or ...

Once viewed as "guideways for the rich and famous," air bearings use in the last two years has been driven by explosive growth in two application areas: flat panel displays and hard disk drives. But ...

This article will examine several examples of how to select the appropriate linear bushing for the application. Impact on performance from material and surface treatments will be discussed.

Rotary Air Bearings provide High Precision Motion with Minimal Eccentricity and Wobble. The rotary air bearing on the left is non motorized – its low friction is apparent from the long time it keeps ...
