The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-BNS-C1-P-1 (R167121222) is a high-precision ball runner block designed for linear motion and guidance applications. This runner block, part of the BNS series, features a body made of unalloyed steel CS and is specifically engineered for precision with an accuracy class P. It is equipped with a low preload, denoted by preload class C, ensuring smooth movement. The product boasts an overall length that allows it to handle high torsional moments effectively on rails and offers the same high load ratings in all four main loading directions. Its design facilitates long-term lubrication over several years while maintaining excellent dynamic characteristics. The runner block also features an integrated all-around sealing system that contributes to its low noise level and optimal travel behavior. Additionally, the B.RUNNER BLOCK CS KWD-025-BNS-C1-P-1 comes prelubricated from the factory with roller bearing grease Dynalub for immediate use and has a straight lube connection loosely attached for ease of maintenance. It does not include attachment elements on either front reference edge but provides two additional mounting screw holes at its center for improved rigidity under liftoff and side-loading conditions. This model is compatible with all BNS ball guide rails, allowing for versatile application across various systems. It also includes an end-face fastening thread and lube connections with metal threads on all sides to accommodate a wide range of accessories. The optimized entry-zone geometry alongside a high number of balls reduces variation in elastic deflection, enhancing system rigidity due to the preloaded O-arrangement. Overall, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-BNS-C1-P-1 (R167121222) runner block is designed for applications that demand very high torsional moment load capacity and resistance, making it ideal as an individual guide in demanding linear motion setups.
