Type SKC Recirculating Unit

Type SKC

The recirculating unit type SKC was developed for minimal lubrication, vacuum and clean room applications. It is made out of DURALLOY® coated stainless steel and has ceramic balls, which are separated from one another by balls made out of TEFLON®. This recirculating unit is used combined with SCHNEEBERGER linear guideways of type R and/or RD. The SKC units can be used in space saving designs that have equal loading in all directions. It is suitable for small to medium loads.
