The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-X-1 (R165121820) is a high-precision ball runner block designed for linear motion on profiled rail systems. This runner block features a size 25 steel CS body with extra precision (XP) accuracy and low preload (class C), ensuring smooth and accurate movement without a ball chain. The product is initially lubricated and preserved, utilizing roller bearing grease Dynalub for long-lasting performance. The B.RUNNER BLOCK CS offers excellent dynamic characteristics, reduced frictional oscillations, and a low friction force level even under external load conditions. Its patented entry zone significantly improves travel accuracy by up to six times compared to standard blocks. The design allows attachments to be mounted from both above and below the block, with lube fittings available on all sides and end-face fastening threads for various attachments. With integrated all-around sealing, the B.RUNNER BLOCK CS is protected against contaminants, contributing to its longevity. It also boasts high torque load capacity and can be used in applications requiring just one runner block per rail due to its rigidity in all load directions. The inclusion of two additional mounting screw holes at the center enhances rigidity under liftoff and side loading conditions. Furthermore, this runner block is compatible with all SN/SNO ball guide rails and comes with an optional integrated, inductive, wear-free measuring system for precise control over movement. Factory pre-lubrication means that it's ready for use upon delivery, while also allowing for long-term lubrication over several years without the need for maintenance. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-X-1 (R165121820) offers maximum precision, rigidity, and durability for linear motion applications that demand the highest standards of performance.
