The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C1-H-1 (R165141322) is a high precision ball runner block designed for linear motion applications requiring high rigidity and accuracy. This runner block features a steel CS body with a size format FNS, which includes a width flange, normal length, and standard height. It has a low preload (class C) and high accuracy (class H), ensuring smooth movement with minimal elastic deflection. The inclusion of a ball chain contributes to low noise levels and optimal travel behavior. The B.RUNNER BLOCK CS is prelubricated with roller bearing grease Dynalub for maintenance-free operation over several years and comes equipped with all-around sealing to protect against contaminants. The product boasts an optimized entry zone geometry that increases travel accuracy by up to six times, suitable for applications demanding maximum precision. With its ability to compensate for misalignments without self-alignment, the runner block also features lube fittings with metal threads on all sides, end face fastening thread for attachments, and additional mounting screw holes at the center for increased rigidity under liftoff and side loading conditions. Its design allows for use on all SNSSNO ball guide rails while maintaining high load ratings in all four main directions of loading. The Bosch Rexroth B.RUNNER BLOCK CS offers various sealing options including standard seals SS, low-friction seals LS, double-lip seals DS, front seals, FKM seals, and cover plate wipers that can be interchanged during servicing. These features make it an ideal component in systems where long-term reliability and performance are essential.
