Bosch Rexroth R16725142Y

What is the Bosch Rexroth R16725142Y?

The ball runner block is highly precise and characterized by the following product features:

Size 20

Format CNS: Width = compact, length = normal, height = standard

Runner block body made of unalloyed steel CS

Preload class C1: Low preload

Accuracy class N: Standard

With 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

Long-term lubrication is possible over several years

Excellent dynamic characteristics

High torque load capacity

Attachments on the ball runner block can be mounted from above

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

Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection

Quiet, smooth running thanks to optimally designed ball and ball chain return and guideway

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 chain for low noise level and best travel behavior

Ball runner block pre-lubricated at the factory
