The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C2-H-1 (R16518232Y) is a robust and highly precise ball runner block designed for linear motion applications requiring high rigidity and precision. This runner block features a size 20 steel CS body, with an FNS format indicating a flange width, normal length, and standard height. It is engineered to provide medium preload (class C) and high accuracy (class H), ensuring optimal performance in demanding situations. The B.RUNNER BLOCK CS is equipped with a ball chain which contributes to low noise levels and smooth travel behavior. For ease of maintenance and enhanced performance, it includes lube fittings with metal threads on all sides, as well as an end-face fastening thread for attachments. The integrated all-around sealing offers protection against contaminants, extending the service life of the runner block. Designed for versatility, the runner block allows for various attachments to be mounted from both above and below. Its optimized entry-zone geometry paired with a high number of balls reduces variation in elastic deflection, thus providing high rigidity in all load directions. This feature enables the use of just one runner block per rail in certain applications. Additional features include improved rigidity under lift-off and side loading conditions due to two extra mounting screw holes at the center of the runner block. The system's maximum rigidity is further enhanced by a pre-tensioned O-arrangement. For applications that require precise measurements, an optional integrated, inductive, wear-free measuring system can be utilized. Pre-lubricated at the factory for immediate use, this ball runner block is compatible with all SN/SNO ball guide rails and maintains high load ratings in all four main loading directions. Its design allows for long-term lubrication over several years without frequent maintenance needs. With its comprehensive set of features tailored for high-performance linear motion systems, the Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C2-H-1 (R16518232Y) stands out as a reliable component for advanced engineering solutions.
