Linear bearings, cross-rollers and ball guideways - linear motion technology

Advantages and customer benefits

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 and the possibility to even out minor angular errors. This briefly summarizes the benefits and advantages of SCHNEEBERGER recirculating units that you as a customer can expect. Most importantly, all of this can be implemented in space-saving designs, equally loaded in all directions, and customized for your requirements.

Unlimited stroke

SCHNEEBERGER recirculating units with balls or rollers support high-precision, rigid, and compact designs with an unlimited stroke. In addition, the standard comes in combination with SCHNEEBERGER type R and RD linear bearings. The components consist of through-hardened tool steel, aluminum transmission parts as well as plastic wipers and damping elements (from size 6 on request). Recirculating units are also available in stainless steel on request.

Balls or rollers

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 right choice is the recirculating unit type SR with crosswise rollers. The type SKC with ceramic and teflon balls is suitable for use in vacuum and cleanroom applications, as well as for dry runs.

Heavy loads

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.
