The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-BNS-C1-N-1 (R167151422) is a high-precision ball runner block designed for linear motion applications. This model features a size 20 steel CS body with a standard width, normal length, and standard height. The runner block boasts a low preload in preload class C and adheres to accuracy class N for standard precision requirements. It includes a ball chain mechanism that ensures smooth, quiet travel and is equipped with initial lubrication and preservation to facilitate immediate use upon installation. The B.RUNNER BLOCK CS KWD-020-BNS-C1-N-1 is characterized by excellent dynamic characteristics, such as high load ratings in all four main loading directions and the capability to handle high torsional moments on rails. It provides long-term lubrication possibilities spanning several years, contributing to reduced maintenance requirements. The product features an integrated all-around sealing system that minimizes contamination ingress, thereby enhancing durability. Designed with two additional mounting screw holes at the center of the runner block, this model offers improved rigidity under lift-off and side-loading conditions. It can be used on all BNS ball guide rails and supports a wide range of accessories due to its end-face fastening thread. The lube connection with metal threads on all sides facilitates easy maintenance. This ball runner block's optimized entry-zone geometry coupled with a high number of balls reduces variation in elastic deflection, ensuring maximum system rigidity when preloaded in an O arrangement. The product is ideal for applications requiring quiet operation, smooth running, high torsional moment load capacity, and superior torsion resistance. Notably, it comes pre-lubricated from the factory for convenience. In terms of technical specifications, the Bosch Rexroth B.RUNNER BLOCK CS KWD-020-BNS-C1-N-1 has an overall length of . mm and can withstand a permissible ambient temperature range from min ... max °C for short durations. Its dynamic load capacity C and static longitudinal moment load capacity ML are determined based on DIN ISO standards for travel lengths up to . m. The product belongs to Productgroup ID .
