The Bosch Rexroth B.RUNNER BLOCK CR KWD-020-CNS-C0-H-1 (R167259372) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and high accuracy. This runner block boasts a Resist CR coating, which provides exceptional corrosion resistance, and is crafted from unalloyed steel CS with a matte-silver, hard chrome-plated finish for durability. The product features a CNS format, indicating a compact width, normal length, and standard height. The B.RUNNER BLOCK CR is preload-free (preload class C) and offers high accuracy (accuracy class H), ensuring precise motion control. It comes equipped with a ball chain to facilitate smooth movement of the balls within the block. The unit arrives prelubricated with Dynalub grease and preserved for immediate use without the need for initial maintenance. With an overall length of . mm, this runner block can be used in conjunction with all BNS ball guide rails across every accuracy class, allowing for interchangeability and flexibility in system design. It has been engineered to handle high torsional moments on rails where lateral space is restricted while maintaining excellent dynamic characteristics. The optimized entry-zone geometry coupled with a high number of balls reduces variation in elastic deflection, enhancing performance. The B.RUNNER BLOCK CR is also notable for its ability to handle heavy loads from all four main directions of loading due to its robust construction. Attachments can be mounted from above onto the runner block, which includes endface fastening threads for all attachments. Two additional mounting screw holes at the center improve rigidity under liftoff and side loading conditions. Designed for quiet and smooth operation, this runner block is ideal as an individual guide in applications where high torque load capacity and torsion resistance are essential. It supports maximum system rigidity through its preloaded O-arrangement and offers compatibility with a wide range of accessories. The permissible ambient temperature range extends from min ... max °C (advisable only for short durations), ensuring reliable performance across various working environments.
