The Bosch Rexroth B.RUNNER BLOCK CS KWC-025-SNN-C0-N-2 (R169429411) is a high-precision ball runner block designed for linear motion applications where space and precision are critical. This runner block is part of the compact series, featuring a slimline width, normal length, and low height profile (SNN format). It is constructed from unalloyed steel CS for durability and robustness. The preload class C indicates that the block is preload-free, meaning there is no additional force applied to the balls in the block, which can reduce system rigidity but allow for smoother movement. With an accuracy class N (standard), this runner block provides reliable performance within standard tolerances. The B.RUNNER BLOCK CS KWC-025-SNN-C0-N-2 has been designed without a ball chain and comes preserved but without initial lubrication, allowing users to apply their choice of lubricant based on specific application requirements. It also lacks attachment elements on both left and right front reference edges but includes angular lube nipples loosely attached for easy maintenance. The product features integrated all-around sealing and end-face fastening threads compatible with various attachments. This ball runner block boasts a patented entry zone that significantly improves travel accuracy—up to six times—and reduces frictional oscillations, especially under external load conditions. It offers long-term lubrication potential over several years and has high torque load capacity. Its dynamic load capacity and load moments are determined according to DIN ISO standards, ensuring compatibility with industry benchmarks. Suitable for use with all Bosch Rexroth SN/SNO ball guide rails, this product allows for self-alignment to compensate for misalignments in the mounting surfaces. The optimized geometry of the entry zone paired with a high number of balls ensures minimal variation in elastic deflection across its operation. For applications requiring measuring systems, an optional integrated, inductive, wear-free measuring system can be added. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWC-025-SNN-C0-N-2 is engineered for applications demanding maximum precision within confined spaces while providing ease of maintenance and long service life due to its robust design features and interchangeable components like seals and wipers available as accessories.
