The Bosch Rexroth B.RUNNER BLOCK CS KWD-015-FNS-C2-U-1 (R165112922) is a high-precision ball runner block designed for linear motion applications requiring utmost accuracy and rigidity. This model features a medium preload class C, ultra-precision accuracy class UP, and is equipped with a ball chain to ensure smooth travel behavior and reduced noise levels. The runner block body is made from unalloyed steel CS, contributing to the system's overall durability. The B.RUNNER BLOCK CS has an optimized entry zone geometry and an increased number of balls, which minimizes the variation in elastic deflection, enhancing travel accuracy by up to six times compared to conventional systems. It boasts high rigidity in all load directions, allowing for the use of just one runner block per rail in certain applications. The design includes two additional mounting screw holes at the center of the block for improved rigidity under liftoff and side loading conditions. This model also features integrated all-around sealing to protect against contaminants, ensuring a long service life. The ball runner block comes pre-lubricated from the factory with roller bearing grease Dynalub, facilitating long-term lubrication over several years without maintenance. It can be used on all SN/SNO ball guide rails and maintains high load ratings in all four main loading directions. Furthermore, this unit allows for attachments to be mounted from both above and below due to its endface fastening thread. It also provides flexibility with lube fittings that have metal threads on all sides for easy access. An optional integrated, inductive and wear-free measuring system can be added for precise positioning tasks. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-015-FNS-C2-U-1 (R165112922) offers maximum precision and rigidity for demanding linear motion applications while ensuring low friction levels, reduced noise operation, and longevity through its robust design and protective features.
