Linear-motion bearings deal with the problem of providing low-friction translational (rather than rotational) motion. Sliding-surface bearings are stiffer and deflect less under load than ...

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 ...

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.
