The Bosch Rexroth B.RUNNER BLOCK CS KWD-015-FNS-C1-U-1 (R165111922) is a ball runner block designed for ultra-precision linear motion applications. This high-precision component features a size 15 runner block body made of unalloyed steel CS, with a low preload class C and an accuracy class UP, indicating its ultra-precision capabilities. It is equipped with a ball chain to ensure smooth, quiet travel and comes pre-lubricated with roller bearing grease Dynalub for immediate use and long-term maintenance-free operation. The B.RUNNER BLOCK CS is characterized by its FNS format, which denotes its flange width, normal length, and standard height. Its robust design incorporates all-around sealing to protect against contaminants and integrated lube fittings with metal threads on all sides for easy maintenance. The product also features endface fastening threads for versatile attachment options. Optimized for high rigidity requirements, the runner block reduces frictional oscillations and maintains a low friction force level even under external load. The patented entry zone increases travel accuracy significantly, enhancing the overall performance of the system. It is designed to provide high rigidity in all load directions, allowing for applications that require only one runner block per rail. Additional product features include high torque load capacity, various preload classes to suit different application needs, an optimized entry zone geometry that minimizes variation in elastic deflection, and the ability to handle increased rigidity under lift-off and side loading conditions thanks to additional mounting screw holes. This model can be used on all SNS/SNO ball guide rails by Bosch Rexroth and offers the same high load ratings in all four main directions of loading. An optional integrated inductive measuring system can be added for precise position feedback without wear concerns. The B.RUNNER BLOCK CS KWD-015-FNS-C1-U-1 represents a reliable solution for demanding linear motion tasks where precision and durability are paramount.
