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 ...

The amount of preload applied can be used to adjust the stiffness (and friction) of the bearing by changing the ball size to as small as 1 µm. Each application is a little bit different. For every ...

Much time and attention is focused on choosing the best bearings for linear motion tasks. But what about the components that guide the application and keep everything in line? Shafting and rails are ...

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 ...
