Unlike conventional ball or roller-based linear guides, hydrostatic guidance systems eliminate all metal-to-metal contact. The guide carriages move on a thin cushion of high-pressure fluid, which ...

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 ...

Design refinements boost performance of self-aligning ball bushing while maintaining their error-correcting nature.

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.
