The Bosch Rexroth B.RUNNER BLOCK CS KWC-025-FNN-C0-H-2 (R169329310) is a high-precision ball runner block designed for linear motion applications where space is limited and accuracy is paramount. This model features a flange width, normal length, and low height format (FNN), with the runner block body crafted from unalloyed steel CS. It belongs to the preload class C, indicating it is preload-free, and it falls within the high accuracy class H. This Bosch Rexroth runner block does not include a ball chain, and it comes preserved but without initial lubrication. It also lacks attachment elements on both left and right front reference edges, but angular lube nipples are loosely attached. The standard version of the runner block body has an overall length specified by the manufacturer. Notably, this model offers interchangeability as both the runner block and guide rails can be combined with each other across every accuracy level. The B.RUNNER BLOCK CS KWC-025-FNN-C0-H-2 boasts several features that enhance its performance: a patented entry zone that significantly increases travel accuracy by up to six times, reduced frictional oscillations, low friction force levels especially under external load conditions, and potential for long-term lubrication spanning several years. The design includes lube fittings with metal threads on all sides for convenience and an end-face fastening thread for various attachments. Additionally, this model has an integrated all-around sealing system that contributes to its high torque load capacity. An optional feature includes an integrated inductive measuring system that is wear-free. The optimized entry-zone geometry coupled with a high number of balls reduces variation in elastic deflection. The B.RUNNER BLOCK CS KWC-025-FNN-C0-H-2 can be employed on all SN/SNO ball guide rails. Attachments can be mounted from both above and below the ball runner block. Its dynamic load capacity C and static torsional moment load capacity Mt are determined based on a 100 km travel as per DIN ISO standards. In terms of environmental adaptability, it can operate within a permissible ambient temperature range specified by the manufacturer's guidelines; however, consultation is recommended for operation at negative temperatures. Overall, this Bosch Rexroth ball runner block is engineered for applications requiring maximum precision combined with durable performance in challenging conditions.
