The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-BNS-C1-H-1 (R167151322) is a high-precision ball runner block designed for linear motion applications requiring high accuracy and low preload. It features a size BNS format with standard width, length, and height dimensions. The runner block body is constructed from unalloyed steel CS, ensuring durability and strength. The low preload class C indicates that the block has been designed to operate with minimal frictional resistance while maintaining a high level of precision. This model boasts an accuracy class H for highly accurate movements and comes equipped with a ball chain to facilitate smooth and quiet travel. The runner block has been pre-lubricated and preserved to extend its service life, allowing for long-term lubrication over several years. This product offers excellent dynamic characteristics, including the ability to withstand high torsional moments on rails, maintain consistent performance in all four main loading directions, and provide improved rigidity under lift-off and side loading conditions due to additional mounting screw holes at the center of the block. Furthermore, the B.RUNNER BLOCK CS KWD-020-BNS-C1-H-1 is compatible with all BNS ball guide rails and includes a comprehensive range of accessories for customization. It features an end-face fastening thread for attachments and multiple lube connection options with metal threads on all sides. The optimized entry-zone geometry along with a large number of balls minimizes variation in elastic deflection. The block's integrated all-around sealing ensures protection against contaminants while maintaining low noise levels and optimal travel behavior. With its very high torsional moment load capacity and exceptional torsion resistance, this ball runner block is ideally suited as an individual guide in demanding linear motion systems.
