SCHNEEBERGER Recirculating units - Unlimited stroke with linear motion

Recirculating units support high-precision, rigid and compact structures with unlimited travel. They are used as standard with linear guideways of type R or RD and offer a high level of accuracy and rigidity with an unlimited stroke. Applications for normal working environments, cleanrooms, or in a vacuum. Suitable sizes and versions for small to heavy loads with the possibility to even correct minor angular errors.

SCHNEEBERGER recirculating units are available in sizes 1-12 and come in various lengths. Types SK and SKD (with damping elements from size 6) are suitable for small to medium loads. For medium to high loads, the best choice is the recirculating unit type SR with cross rollers. The type SKC with ceramic and Teflon balls is suitable for use in vacuum and cleanroom applications, as well as for dry runs.

The type NRT is a roller recirculating unit designed for medium to heavy loads. Thanks to two independent tracks, optimized roller geometry, and with very little play in the rollers, there is minimal lateral force. Together with suitable linear bearings, solutions can be implemented for the most demanding requirements. SCHNEEBERGER also offers the NRV type preload wedge with concave and convex supporting surfaces. This model is perfect for managing minor angular errors and deformations in the base structures.
