The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C2-U-1 (R16514292Y) is a high-precision ball runner block designed for use in demanding linear motion applications. The runner block body is made from unalloyed steel CS, ensuring durability and robustness. This model features an ultra precision accuracy class (UP), medium preload class (C), and comes with a ball chain that contributes to low noise levels and optimal travel behavior. It is prelubricated with roller bearing grease Dynalub, offering initial lubrication and preservation for long-term performance. The B.RUNNER BLOCK CS KWD-045-FNS-C2-U-1 is characterized by its FNS size format, which indicates a width flange, normal length, and standard height. It boasts high rigidity requirements, significantly reduced frictional oscillations, and maintains a low friction force level even under external load. The patented entry zone of the runner block enhances travel accuracy by up to six times. This Bosch Rexroth runner block is versatile with attachments mountable from both above and below. It includes lube fittings with metal threads on all sides for easy maintenance and an endface fastening thread for secure attachment of accessories. Its integrated all-around sealing provides protection against contaminants, extending the service life of the component. Designed to accommodate high torque loads and support various preload classes, this runner block also features optimized entry zone geometry with numerous balls to minimize variation in elastic deflection. Its rigidity allows for single runner block applications per rail while maintaining system integrity under liftoff and side loading conditions thanks to additional mounting screw holes at the center. An optional feature includes an integrated, inductive, wear-free measuring system for precise positioning tasks. The B.RUNNER BLOCK CS can be paired with all SN/SNO ball guide rails while maintaining consistent load ratings in all four main directions of loading. Its design facilitates long-term lubrication over several years without frequent maintenance interventions.
