Description

The ball runner block is highly precise and characterized by the following product features:
Size 25
Format BNS: Width = wide, 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 = 105.0 mm
Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy.
Area of application: For high torsional moments on rails
The same high load ratings in all four main directions of loading
Long-term lubrication is possible over several years
Excellent dynamic characteristics
Attachments on the ball runner block can be mounted from above and below
High torque load capacity
Integrated all-round sealing
Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the ball runner block
Can be used on all BNS ball guide rails
Wide range of accessories
End-face fastening thread for all attachments
Lube connection with metal thread on all sides
Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection
Maximum system rigidity due to preloaded O-arrangement
Very high torsional moment load capacity and very high torsion resistance – therefore primarily used as an individual guide
Ball runner block pre-lubricated at the factory
