The ball runner block is highly precise and corrosion-resistant thanks to its Resist CR coating. Additionally, it is characterized by the following product features:
Size 20
Format CNS: Width = compact, length = normal, height = standard
Runner block body made of unalloyed steel CS, matte-silver, hard chrome plated
Preload class C0: Preload-free
Accuracy class H: High
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 = 73.0 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 with restricted lateral space
- The same high load ratings in all four main directions of loading
- Excellent dynamic characteristics
- Ball runner block body or ball guide rail made of steel with corrosion resistant coating, matte-silver finish, hard chrome plated
- High torque load capacity
- Attachments on the ball runner block can be mounted from above
- End-face fastening thread for all attachments
- Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection
- Can be used on all BNS ball guide rails
- Maximum system rigidity due to preloaded O-arrangement
- Wide range of accessories
- Ball runner block pre-lubricated at the factory
- Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the ball runner block
- Very high torsional moment load capacity and very high torsion resistance – therefore primarily used as an individual guide
