The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-CNS-C1-N-1 (R167221420) is a high-precision ball runner block designed for linear motion and guidance applications. This product boasts a compact width, normal length, and standard height (CNS format), making it suitable for areas with limited lateral space but requiring high torsional moment capacity. The runner block body is constructed from unalloyed steel CS, ensuring durability and robustness in operation. Featuring a low preload class C and a standard accuracy class N, this runner block is engineered for smooth movement with a low friction coefficient. It comes without a ball chain but includes initial lubrication and preservation to facilitate immediate use upon installation. The roller bearing grease Dynalub enhances the longevity of the component. This runner block has an overall length of . mm and offers excellent dynamic characteristics, capable of withstanding high load ratings in all four main directions of loading. It supports long-term lubrication over several years and provides impressive rigidity under liftoff and side loading conditions due to two additional mounting screw holes at the center. The B.RUNNER BLOCK CS KWD-025-CNS-C1-N-1 is compatible with all BNS ball guide rails, allowing for interchangeability across various accuracy levels. Its integrated all-around sealing improves protection against contaminants, while the optimized entry-zone geometry ensures minimal variation in elastic deflection, contributing to maximum system rigidity. With its preloaded O-arrangement, this ball runner block can handle very high torsional moment load capacities and resist torsion effectively, making it an ideal choice for individual guide applications where precision is paramount. The product also features a wide range of accessories and end-face fastening threads for easy attachment options.
