Description

The ball runner block is highly precise and characterized by the following product features:
Size 20
Format FLS: Width = flange, length = long, 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 = 91.0 mm
Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy.
Area of application: For the most demanding rigidity requirements
Significantly reduced frictional oscillations and low friction force level, particularly under external load
Excellent dynamic characteristics
Maximum precision
Patented entry zone increases the travel accuracy up to a factor of six
Long-term lubrication is possible over several years
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
Attachments on the ball runner block can be mounted from above and below
Can be used on all SNS/SNO ball guide rails
The same high load ratings in all four main directions of loading
Ball runner block pre-lubricated at the factory
