The Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FNS-C1-H-1 (R165131321) is a high-precision ball runner block designed for linear motion applications requiring high rigidity and accuracy. This runner block is made of unalloyed steel CS and features a size FNS format, which denotes its width, flange, normal length, and standard height. It has a low preload class C and an accuracy class H, ensuring highly accurate movements without a ball chain. The product boasts various attributes that contribute to its performance and durability. It offers excellent dynamic characteristics with reduced frictional oscillations and a low friction force level, particularly under external load. The patented entry zone increases travel accuracy up to six times compared to conventional designs. The runner block body comes in the standard version with an overall length of . mm. One of the key advantages of this ball runner block is its versatility in mounting options; attachments can be mounted from both above and below the block. It includes metal-threaded lube fittings on all sides for easy lubrication access, as well as end-face fastening threads for attaching elements securely. In terms of sealing, this model features integrated all-around sealing to protect against contaminants while maintaining high torque load capacity. Various preload classes are available to suit different application needs, and the design accommodates high rigidity in all load directions, allowing for single-runner-block applications on a rail. For enhanced system rigidity, the design includes two additional mounting screw holes at the center of the runner block. An optional integrated inductive measuring system can be added for wear-free operation. The B.RUNNER BLOCK CS comes prelubricated from the factory and is compatible with all SN/SNO ball guide rails offered by Bosch Rexroth. This model supports long-term lubrication over several years and maintains consistent high load ratings in all four main loading directions due to its robust construction. It's suitable for various industrial applications where precision linear movement is critical.
