Maximum precision

Patented entry zone increases the travel accuracy up to a factor of six

Attachments on the ball runner block can be mounted from above and below

Lube fittings with metal threads on all sides

End-face fastening thread for all attachments

Integrated all-round sealing

High torque load capacity

Different preload classes

High rigidity in all load directions – permits applications with just one runner block per rail

Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the ball runner block

Maximum system rigidity due to preloaded O-arrangement

Optional integrated, inductive and wear-free measuring system

Ball runner block pre-lubricated at the factory

Can be used on all SNS/SNO ball guide rails
