The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C3-U-1 (R16518392Y) is a high-precision ball runner block designed for linear motion applications that demand ultra precision and high rigidity. This runner block features a size 20 steel CS body with an FNS format indicating a flange width, normal length, and standard height. It is engineered with high preload (class C) and ultra precision accuracy (class UP), ensuring maximum precision in operation. Equipped with a ball chain, the B.RUNNER BLOCK CS offers reduced frictional oscillations and low friction force levels, especially under external load conditions. The patented entry zone of the runner block increases travel accuracy significantly—up to six times compared to standard models. This model also boasts an all-around sealing system for protection against contaminants, enhancing its longevity and reliability. For applications requiring high torque load capacity, this runner block includes end-face fastening threads for attachments and lube fittings with metal threads on all sides. The optimized entry zone geometry paired with a high number of balls reduces variation in elastic deflection, providing high rigidity in all load directions which allows for the use of just one runner block per rail in certain applications. Additional features include improved rigidity under liftoff and side loading conditions due to two extra mounting screw holes at the center of the unit. The B.RUNNER BLOCK CS can be integrated into systems that require maximum system rigidity due to its preloaded O-arrangement. An optional integrated, inductive, and wear-free measuring system can be added for precise monitoring. Pre-lubricated at the factory with roller bearing grease Dynalub, this ball runner block is designed for long-term lubrication over several years without the need for frequent maintenance. It boasts compatibility with all SN/SNO ball guide rails and maintains high load ratings in all four main loading directions. With its robust construction and advanced design features, the Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C3-U-1 is tailored to meet stringent requirements in terms of precision linear movement and overall system performance.
