Type SK and SKD
The type SK recirculating unit is equipped with balls and is suitable for small to medium loads.
This recirculating unit is used combined with SCHNEEBERGER linear guideways of type R and/or RD. The SK units can be used in space saving designs that have equal loading in all directions.
Sizes 6 and 9 (size 12 on request) can additionally be equipped with damping elements (type designation SKD). These provide improved smoothness with slightly reduced load carrying capacity.
