The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-X-1 (R165121823) 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 crafted from unalloyed steel CS, ensuring durability and strength. It features a size FNS format, which denotes its width, flange, normal length, and standard height dimensions. The low preload class C and extra precision accuracy class XP make it suitable for applications where smooth motion and reduced frictional oscillations are critical. Equipped with a ball chain, the runner block ensures low noise levels and optimal travel behavior. The initial lubrication and preservation with roller bearing grease Dynalub facilitate maintenance-free operation for extended periods. The unit's straight lube connection allows for easy access to lubrication points. The Bosch Rexroth B.RUNNER BLOCK CS has been engineered with an optimized entry zone geometry and a high number of balls to minimize variations in elastic deflection. It boasts high rigidity in all load directions, making it possible to use just one runner block per rail in certain applications. The design includes additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. This model also features an integrated all-around sealing system that protects against contaminants, enhancing service life and reliability. The end-face fastening thread accommodates various attachments from above or below without the need for attachment elements at the front reference edges. The Bosch Rexroth B.RUNNER BLOCK CS can be combined with guide rails of every accuracy level due to its interchangeability feature. Its design allows for maximum system rigidity through a preloaded O-arrangement, ensuring consistent performance even under varying load conditions. Optional add-ons include an integrated, inductive measuring system that provides wear-free operation. In summary, this ball runner block is engineered to meet the demands of high-precision applications while offering flexibility in design integration and long-term reliability through advanced sealing technology and robust construction materials.
