The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C1-H-1 (R165181322) is a high-precision ball runner block designed for linear motion systems requiring high rigidity and precision. This runner block features a size E profile, with a flange width (FNS format), normal length, and standard height. Constructed from unalloyed steel CS, it offers low preload (Preload class C) and high accuracy (Accuracy class H), ensuring smooth motion and reduced frictional oscillations, especially under external loads. The runner block is equipped with a ball chain to facilitate quiet operation and optimal travel behavior. Initial lubrication and preservation are provided, along with the high-performance roller bearing grease Dynalub. It lacks attachment elements at the left and right front reference edges but includes straight lube connections that are loosely attached. This product boasts an innovative entry zone that can increase travel accuracy by up to six times, alongside the ability to mount attachments from above or below. The all-around sealing integrated into the design provides protection against contaminants, enhancing the runner block's longevity. The design also features high torque load capacity, various preload classes, and optimized geometry to minimize elastic deflection variations. The B.RUNNER BLOCK CS KWD-020-FNS-C1-H-1 is compatible with all SN/SNO ball guide rails, offering uniform load ratings in all four main loading directions. It supports long-term lubrication over years of use without sacrificing performance. Additionally, it has been prelubricated at the factory for immediate deployment in linear motion applications. This runner block's robust construction allows for single-block applications per rail while maintaining system rigidity thanks to additional center mounting screw holes that enhance its structural integrity under liftoff and side-loading conditions. Optional features include an integrated inductive measuring system for wear-free operation. Its versatile design ensures interchangeability with guide rails of every accuracy level within its class, making it suitable for a wide range of precision applications in various fields requiring linear motion solutions.
