The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-BNS-C1-H-1 (R167121322) is a highly precise ball runner block designed for linear motion applications requiring high accuracy and low noise operation. This product is part of the BNS series, featuring a wide format with normal length and standard height. The runner block body is constructed from unalloyed steel CS, ensuring durability and robust performance. With a preload class C indicating low preload and an accuracy class H for high precision, this runner block is engineered to deliver reliable guidance with minimal play. It includes a ball chain which contributes to smooth and quiet movement, as well as initial lubrication and preservation for long-term maintenance-free operation. The runner block boasts excellent dynamic characteristics, capable of handling high torsional moments on rails and maintaining the same high load ratings in all four main directions of loading. It has been designed to offer improved rigidity under liftoff and side loading conditions due to two additional mounting screw holes at the center. This model also features an integrated all-around sealing system that provides protection against contaminants, contributing to its longevity. Attachments on the ball runner block can be mounted from both above and below, offering flexibility in installation. Furthermore, it has an optimized entry-zone geometry which, along with a high number of balls, minimizes variation in elastic deflection thereby maximizing system rigidity. The B.RUNNER BLOCK CS KWD-025-BNS-C1-H-1 is prelubricated at the factory for immediate use upon delivery. Its design allows for maximum permissible linear speed and dynamic load capacity while maintaining low friction coefficients. The product also supports a wide range of ambient operating temperatures. In summary, this Bosch Rexroth ball runner block is suitable for applications demanding precise linear motion with high load capacity, low noise emission, optimal travel behavior, and resistance to torsional loads.
