The Bosch Rexroth B.RUNNER BLOCK CS KWC-025-FNN-C0-N-2 (R169329410) is a high-precision ball runner block designed for linear motion systems. This component features a size 25 runner block body constructed from unalloyed steel CS, ensuring durability and robustness. It is part of the FNN format, which signifies a flanged width, normal length, and low height configuration. The ball runner block comes with an accuracy class N (standard) and a preload class C (preload-free), making it suitable for applications requiring precise movement without pre-tensioning in the system. This model is designed without a ball chain and is preserved but does not include initial lubrication or attachment elements on either front reference edge. However, it does come with angular lube nipples loosely attached for ease of maintenance. The overall length of the runner block is optimized to work interchangeably with guide rails of every accuracy level, enhancing compatibility across different setups. One of the key features of this ball runner block is its patented entry zone that significantly increases travel accuracy—up to six times—while also reducing frictional oscillations and maintaining a low friction force level even under external load conditions. Long-term lubrication capabilities extend over several years, reducing maintenance frequency. Moreover, the B.RUNNER BLOCK CS KWC-025-FNN-C0-N-2 offers high torque load capacity and can accommodate various attachments from above or below due to its end-face fastening thread design. Its integrated all-round sealing protects against contaminants while maintaining performance integrity. For applications requiring further precision, an optional integrated, inductive, and wear-free measuring system can be added. In summary, this Bosch Rexroth ball runner block provides maximum precision with reduced friction and long-term lubrication possibilities within a compact design that ensures interchangeability and easy integration into existing linear motion systems.
