Available in eight common sizes

Area of application: For maximum speeds

Significantly reduced frictional oscillations and low friction force level, particularly under external load

High speed thanks to the low weight of ceramic balls

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

Attachments on the ball runner block can be mounted from above

Lube fittings with metal threads on all sides

Maximum system rigidity due to preloaded O-arrangement

Electrically insulating due to use of ceramic balls

Excellent dynamic characteristics

Limitless interchangeability as all ball guide rail systems can be combined at will with all ball runner block versions within each accuracy class.
