The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FLS-C1-H-1 (R165381322) is a high-precision ball runner block designed for linear motion applications requiring maximum rigidity and accuracy. This runner block features a steel CS body, with dimensions tailored to provide a flange width, long length, and standard height. The low preload class C ensures smooth movement with minimal resistance, while the high accuracy class H guarantees exceptional precision in positioning. Equipped with a ball chain, this runner block offers reduced frictional oscillations and maintains a low friction force level even under external loads. The dynamic characteristics of the B.RUNNER BLOCK are further enhanced by its excellent rigidity in all load directions, making it suitable for applications that require only one runner block per rail. The inclusion of two additional mounting screw holes at the center of the unit improves rigidity under liftoff and side-loading conditions. For extended service life without frequent maintenance, this model is designed to support long-term lubrication over several years and comes pre-lubricated from the factory. The integrated all-around sealing protects against contaminants, ensuring reliable operation in various environments. Furthermore, the B.RUNNER BLOCK CS KWD-020-FLS-C1-H-1 offers flexibility in assembly with end-face fastening threads for various attachments and lube fittings with metal threads on all sides. It also provides optional features such as an integrated inductive measuring system for wear-free operation. This ball runner block is compatible with all SNS/SNO ball guide rails from Bosch Rexroth and maintains high load ratings across four main loading directions. Its design enables easy interchangeability with guide rails of every accuracy level, supporting diverse application requirements while ensuring maximum system rigidity through its preloaded O-arrangement.
