Cross Roller Guide KRVR
In the rolling element cage, from which these guides also get their name, rollers can be arranged either parallel or in a so-called crossed arrangement.
The R-linear guide / crossed roller guide and ball guide were introduced as the world’s first standardized rolling element guides. The guide can be equipped with rollers or balls and is suitable for many applications with medium to high requirements.
Cross roller guides run very smoothly and show no run-in shocks when the rollers move continuously between the rails. Cage creep is problematic with standard crossed roller guides, which makes occasional correction strokes necessary. To prevent this, controlled cages are available to avoid roller creep.
Cross roller guides are often used in measuring systems, grinding machines, and very precise cutting devices.
