The Bosch Rexroth B.RUNNER BLOCK CS KWD-030-FNS-C3-S-1 (R165173122) is a highly precise ball runner block designed for linear motion applications that demand maximum precision and rigidity. This runner block features a steel CS body with an FNS format, indicating its flange width, normal length, and standard height. It is preloaded to class C for high preload and falls under the super precision accuracy class SP. The B.RUNNER BLOCK CS includes a ball chain to ensure low noise operation and smooth travel behavior. The product comes prelubricated with roller bearing grease Dynalub, which along with the integrated all-around sealing allows for long-term lubrication over several years without the need for maintenance. The dynamic load capacity C and static torsional moment load capacity Mt are determined based on a 100,000 m travel as per DIN ISO standards. This runner block is self-aligning to compensate for any misalignments and boasts an optimized entry zone geometry with a high number of balls to minimize variation in elastic deflection. Its design ensures high rigidity in all load directions, enabling the use of just one runner block per rail if necessary. For applications that involve liftoff or side loading conditions, additional mounting screw holes at the center of the runner block provide improved rigidity. An optional feature available for this model is an integrated, inductive, wear-free measuring system that enhances its application potential. The B.RUNNER BLOCK CS can be used on all SN/SNO ball guide rails and maintains high load ratings in all four main directions of loading. Its design also includes lube fittings with metal threads on all sides and an end-face fastening thread for attachments. Overall, this product is engineered to meet rigorous requirements where frictional oscillations are significantly reduced and where maximum system rigidity is essential due to its preloaded O-arrangement.
