The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C1-P-1 (R165141222) is a highly precise ball runner block designed for linear motion applications requiring high rigidity and precision. This runner block is part of the Ball Rail Systems product group and is distinguished by its FNS format, which denotes a flange width, normal length, and standard height. Made from unalloyed steel CS, it offers low preload (Preload class C) and precision accuracy (Accuracy class P), ensuring smooth and accurate operation. Equipped with a ball chain, the B.RUNNER BLOCK CS minimizes noise levels while optimizing travel behavior. It features initial lubrication and preservation with roller bearing grease Dynalub for reliable performance over time. The runner block body comes in a standard version without attachment elements at the front reference edges but includes straight lube connections loosely attached. Designed to handle high load capacities in all four main directions of loading, this runner block can be used with just one unit per rail due to its high rigidity. The optimized entry zone geometry coupled with a high number of balls reduces variation in elastic deflection. Additional mounting screw holes at the center enhance rigidity under liftoff and side loading conditions. An optional integrated, inductive measuring system can be added for wear-free operation. The B.RUNNER BLOCK CS is prelubricated at the factory for convenience and can be used on all SNSSNO Ball Guide Rails. It also features an integrated all-around sealing system to protect against contaminants which extends its service life even further. This model's overall length is specified as well as its compatibility with Size E profiled rail systems, ensuring interchangeability across different accuracy classes. Its design allows for long-term lubrication over several years, reducing maintenance requirements. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C1-P-1 (R165141222) offers maximum precision and rigidity for various linear motion applications while maintaining low friction levels and providing long-lasting performance through robust construction and thoughtful design features like ball chains and comprehensive sealing options.
