The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C0-H-1 (R165129322) is a high-precision ball runner block designed for linear motion applications requiring rigidity and accuracy. This runner block is part of the Ball Rail Systems product group, which is known for its low friction levels due to the four rows of balls providing point contact in all loading directions. The B.RUNNER BLOCK CS features a size 25 steel body with high accuracy (class H) and is preload-free (class C), ensuring smooth movement without pre-tension. The product comes with a ball chain to ensure low noise operation and optimal travel behavior. It includes lube fittings with metal threads on all sides for easy maintenance, as well as an end-face fastening thread for various attachments. The integrated all-around sealing offers protection against contaminants, thereby extending the service life of the runner block. This model has been designed with an optimized entry-zone geometry and a high number of balls to minimize variation in elastic deflection, enhancing rigidity under all load directions. This makes it possible to use just one runner block per rail in certain applications. Additionally, two extra mounting screw holes at the center of the runner block improve rigidity under lift-off and side-loading conditions. The B.RUNNER BLOCK CS can be used on all SN/SNO ball guide rails and supports high load ratings in four main directions of loading. It comes pre-lubricated from the factory for long-term lubrication over several years, reducing maintenance requirements. Its versatile design allows for use in various industrial applications where precision linear motion is critical. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C0-H-1 (R165129322) stands out for its high precision, ease of maintenance, robust performance under varying loads, and compatibility with a wide range of guide rails within Rexroth's Ball Rail Systems.
