Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy.
Area of application: For high rigidity requirements
Heavy-duty Ball Runner Block for heavy machine construction with extremely high load-bearing capacity
Maximum rigidity in all load directions
Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the ball runner block
High torque load capacity
Attachments on the ball runner block can be mounted from above and below
Minimum lubrication quantities thanks to innovative channel design
Smooth, quiet running thanks to optimally designed ball return and guideway
Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection
Different preload classes
End-face fastening thread for all attachments
Can be used on all SNS ball guide rails
Limitless interchangeability as all ball guide rail versions can be combined at will with all ball runner block versions
