The Bosch Rexroth B.RUNNER BLOCK CS KWD-015-FNS-C2-U-1 (R165112920) is a high-precision ball runner block designed for linear motion applications requiring exceptional rigidity and accuracy. This runner block features a steel CS body, with an FNS format indicating a flanged width, normal length, and standard height. The product is distinguished by its ultra precision (UP) accuracy class and medium preload (class C), ensuring smooth motion and reliable performance under medium preloading conditions. The B.RUNNER BLOCK CS comes without a ball chain but includes initial lubrication and preservation for immediate use. It boasts an overall length of . mm and can be easily combined with guide rails of every accuracy, enhancing its versatility across various applications. Its design facilitates excellent dynamic characteristics, with significantly reduced frictional oscillations and low friction levels even when external loads are applied. Key features include a patented entry zone that improves travel accuracy by up to six times, attachments that can be mounted from both above and below the runner block, metal-threaded lube fittings on all sides, endface fastening threads for all attachments, and integrated all-around sealing. The product is capable of handling high torque loads while maintaining high rigidity in all load directions—this allows for the use of just one runner block per rail in certain applications. Additional benefits include improved rigidity under lift-off and side loading conditions due to extra mounting screw holes at the center of the runner block. The B.RUNNER BLOCK CS also offers maximum system rigidity through its preloaded O-arrangement. Options include an integrated, inductive measuring system for wear-free operation. Pre-lubricated at the factory, it is compatible with all SN/SNO ball guide rails from Bosch Rexroth. Long-term lubrication over several years is possible with this model, which also provides equal high load ratings in all four main loading directions. This makes it suitable for diverse industrial uses where precision linear movement is critical.
