Cross roller guide LWR

Cross roller guide LWR - KRVC

In the rolling element cage, from which these guides get their name, rollers can be held in parallel or in the so-called crossed roller arrangement.
The R linear guide / crossed roller guide and ball guide was introduced as the first standardized rolling guide in the world. The guide can be equipped with rollers or balls and is suitable for many applications in the medium to high requirement range.
Crossed roller guides run very smoothly and have no impact when the rollers move constantly between the rails. Cage wandering is problematic with standard crossed roller guides. This makes it necessary to carry out correction strokes occasionally. To avoid this, there are controlled cages that prevent the cross rollers from moving.

Crossed roller guides are often used in measuring systems, grinding machines or very precise cutting devices (microtome cutting).
