The ball runner block is highly precise and characterized by the following product features:
Size 20
Format FNS: Width = flange, length = normal, height = standard
Runner block body made of unalloyed steel CS
Preload class C1: Low preload
Accuracy class N: Standard
Without ball chain
With initial lubrication and preservation
Roller bearing grease Dynalub 510
Without attachment element, left (front reference edge)
Without attachment element, right (front reference edge)
Straight lube connection loosely attached.
Runner block body in standard version
Overall length of the runner block = 75.0 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
• Excellent dynamic characteristics
• Significantly reduced frictional oscillations and low friction force level, particularly under external load
• 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
• Long-term lubrication is possible over several years
• The same high load ratings in all four main directions of loading
