Rexroth 167151420
Wózki liniowe
The ball runner block is highly precise and characterized by the following product features:
Size 20
Design BNS: Width = wide, length = normal, height = standard
Runner block body made of carbon steel CS
Preload class C1: Low preload
Accuracy class N: Normal
Without ball chain
With initial lubrication and preservation
Bearing grease Dynalub 510
Without attachment element, left (reference edge in front)
Without attachment element, right (reference edge in front)
Straight lube connection loosely attached.
Runner block body as standard version
Overall length of the runner block= 73,0 mm
Interchangeability: The runner blocks and the guide rails can be combined as desired within each accuracy class.
- 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
