The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-BNS-C0-H-1 (R167129322) is a high-precision ball runner block designed for linear motion systems. This runner block is part of the profiled rail systems and features a size N, which corresponds to specific dimensions and tolerance profiles. The body of the runner block is made from unalloyed steel CS, ensuring durability and strength for demanding applications. With a preload class C, this model is preload-free, which means there is no initial force between the ball bearings and the running track, allowing for smooth movement without additional resistance. The accuracy class H signifies that this runner block has high accuracy, making it suitable for applications where precise positioning is critical. The B.RUNNER BLOCK CS KWD-025-BNS-C0-H-1 comes equipped with a ball chain that contributes to low noise levels and optimal travel behavior. It also features an integrated all-around sealing system to protect against contamination from dust, chips, or other environmental factors. This sealing system contributes to the unit's longevity and consistent performance over time. This model has been pre-lubricated at the factory with roller bearing grease Dynalub 510 for immediate use and potential long-term lubrication over several years. It also boasts excellent dynamic characteristics such as high load ratings in all four main directions of loading, which makes it capable of handling high torsional moments on rails. Additionally, attachments can be mounted from both above and below the runner block, providing flexibility in design configurations. The optimized entry-zone geometry along with a high number of balls reduces variation in elastic deflection, ensuring maximum system rigidity especially in preloaded O-arrangement setups. This ball runner block can be used on all BNS ball guide rails and comes with a wide range of accessories including end-face fastening thread for all attachments. Its design allows for improved rigidity under lift-off and side-loading conditions due to two additional mounting screw holes at the center of the runner block. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-BNS-C0-H-1 (R167129322) offers exceptional precision, flexibility in mounting options, robust protection against environmental factors, low noise operation, excellent dynamic characteristics, and very high torsional moment load capacity suitable for various linear motion applications.
