The Bosch Rexroth B.RUNNER BLOCK CR KWD-020-CNS-C0-H-1 (R16725937Y) is a high-precision ball runner block designed for use in linear motion applications where corrosion resistance and high accuracy are required. This runner block features a Resist CR coating, which provides exceptional corrosion resistance, and it comes in a compact width, normal length, and standard height format (CNS). The body of the runner block is made from unalloyed steel CS with a matte-silver finish and hard chrome plating. This model is preload-free (preload class C) and offers high accuracy (accuracy class H), ensuring smooth motion and reliable performance. It includes a ball chain to maintain consistent recirculation of the balls, initial lubrication, preservation, and roller bearing grease Dynalub for reduced maintenance needs. The overall length of this runner block is specified in the product features. The B.RUNNER BLOCK CR KWD-020-CNS-C0-H-1 has been designed to handle high torsional moments on rails with restricted lateral space while maintaining the same load ratings in all four main loading directions. It exhibits excellent dynamic characteristics due to its optimized entry-zone geometry and a large number of balls that minimize variation in elastic deflection. Its design also allows for end-face fastening threads for attachments, providing maximum system rigidity when used in preloaded O-arrangements. Additionally, this ball runner block can be used with all BNS ball guide rails and offers improved rigidity under liftoff and side loading conditions thanks to additional mounting screw holes at its center. The quiet and smooth operation is achieved through an optimally designed ball return system. With its high torsional moment load capacity, it is primarily used as an individual guide where precise linear motion is crucial. In terms of environmental considerations, it can operate within an ambient temperature range from -10°C up to 100°C for short periods. For extreme temperature applications or further technical details such as dynamic load capacities or specific dimensions like height or width of the runner block or guide rails involved, users should refer to the product specifications provided by Bosch Rexroth.
