BALL RUNNER BLOCK CARBON STEEL KWD-025-BNS-C1-N-1

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.

Features

• 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
