Cross roller guides: overview, characteristics and applications

June 15, 2024

Crossed roller guides are designed for limited strokes and consist of two hardened rails with a crossed roller cage for bearing support in between. The use of rolling bearings allows for a low friction coefficient of <0.003. The rollers which are 90 degrees angled to each other, are held in place by a cage. These linear guides are suitable for applications with the highest precision requirements. Read more
