The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C1-H-1 (R165181321) is a high-precision ball runner block designed for linear motion applications requiring rigidity, precision, and smooth operation. This runner block is part of the Ball Rail System, which offers interchangeability and compatibility with SN/SNO ball guide rails. Its size and FNS format indicate a flanged width, normal length, and standard height configuration. Made from unalloyed steel CS, the runner block features a low preload (class C) and high accuracy (class H), ensuring precise movement without the inclusion of a ball chain. The B.RUNNER BLOCK CS KWD-020-FNS-C1-H-1 is distinguished by its ability to handle high rigidity demands with excellent dynamic characteristics. The patented entry zone amplifies travel accuracy significantly, reducing frictional oscillations and maintaining low friction levels even under external load. It can accommodate attachments both above and below the block while providing all-around sealing and multiple lube fittings with metal threads for easy maintenance. With its integrated sealing system, it offers protection against contaminants such as dirt or chips. The product comes pre-lubricated from the factory for long-term use without frequent maintenance. It boasts a high torque load capacity, allowing for applications that require only one runner block per rail due to its robust design that includes additional mounting screw holes at the center for improved side loading conditions. The B.RUNNER BLOCK CS KWD-020-FNS-C1-H-1 also features an optional integrated inductive measuring system that provides wear-free operation. Its design ensures maximum system rigidity through a pre-tensioned O arrangement. The dynamic characteristics of this runner block are suited for various applications where precision and durability are key factors in achieving optimal performance in linear motion systems.
