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 ...

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 ...

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.
