The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C1-U-1 (Material Number R16514192Y) is a high-precision ball runner block designed for linear motion applications requiring ultra precision and low preload. This runner block features a body made of unalloyed steel CS and comes with a ball chain, ensuring smooth, quiet travel behavior and consistent performance. The model is part of the FNS format, which indicates a flange width, normal length, and standard height. Engineered for high rigidity requirements, this runner block significantly reduces frictional oscillations and maintains a low friction force level even under external load conditions. The patented entry zone of the runner block increases travel accuracy by up to six times. Designed for versatility, attachments can be mounted from both above and below the runner block. The product comes prelubricated with roller bearing grease Dynalub for initial use and has an overall length of . mm. It is notable for its interchangeability feature; it can be combined with guide rails of every accuracy level to meet various application needs. The Bosch Rexroth B.RUNNER BLOCK CS also boasts an integrated all-around sealing system for protection against contaminants, high torque load capacity, and different preload classes to suit specific requirements. For enhanced performance, the optimized entry zone geometry coupled with a high number of balls minimizes variation in elastic deflection. Its design allows for high rigidity in all load directions which permits applications to use just one runner block per rail if needed. Additional mounting screw holes at the center improve rigidity under liftoff and side-loading conditions. With long-term lubrication capabilities extending over several years, this ball runner block is suitable for all SN/SNO ball guide rails offering consistent high load ratings in all four main directions of loading. Its static torsional moment load capacity Mt ensures it can handle significant loads while maintaining stability and precision in motion control applications.
