Runner block body in standard version
Overall length of the runner block = 159.0 mm
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 centre 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.
