The Bosch Rexroth B.RUNNER BLOCK CS KWD-030-FNS-C2-U-1 (R165172922) is a high-precision ball runner block designed for linear motion applications requiring extreme accuracy and rigidity. This runner block is part of the Ball Rail Systems product group and is specifically tailored for use with size E profiled rail systems. It features a flanged width, normal length, and standard height (FNS format), constructed from unalloyed steel CS, ensuring durability and strength. With an accuracy class of UP (Ultra Precision) and preload class C (Medium preload), this runner block offers superior precision and pre-tensioning for optimal performance. The inclusion of a ball chain contributes to a low noise level and smooth travel behavior, while the initial lubrication and preservation ensure long-term reliability without the need for frequent maintenance. The B.RUNNER BLOCK CS boasts an optimized entry zone geometry coupled with a high number of balls to minimize elastic deflection variation, enhancing its ability to maintain precision under various load conditions. It also has high torque load capacity, making it suitable for applications that require just one runner block per rail. The design includes two additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. Furthermore, this model comes with integrated all-around sealing to protect against contaminants, contributing to its long service life. It can be used on all SN/SNO ball guide rails with the same high load ratings in all four main directions of loading. For specialized applications, an optional integrated inductive and wear-free measuring system can be added. To facilitate various attachment configurations, the B.RUNNER BLOCK CS has endface fastening threads and lube fittings with metal threads on all sides. Its compatibility with different preload classes allows users to choose the appropriate level of pre-tensioning based on their specific application requirements. Overall, this Bosch Rexroth ball runner block is engineered to deliver maximum system rigidity and precision in demanding linear motion tasks.
