The Basics of Crossed Roller Bearings

Sponsored by NB Corporation

Crossed roller bearings provide more accuracy, rigidity, and weight-bearing capacity for linear motion than other commonly used friction-reducing devices such as ball bear­ings. And unlike ball bearings, they can support moment loads, radial forces or tilting loads. This lets one crossed roller bearing replace more than one ball bearing, thus saving the space required by ball bearings, lowering the associated material costs.

In this guide, we’ll review crossed roller bearing basics including preventing cage creep and travel lengths. We’ll also take a look at trends in the use of linear crossed roller bearings.
