The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-S-1 (R165121120) is a highly precise ball runner block designed for linear motion systems. This component is part of the Ball Rail Systems product line and offers superior performance characteristics for applications requiring high rigidity and dynamic capabilities. The runner block body is constructed from unalloyed steel CS, ensuring durability and strength. It features a low preload class C and an accuracy class SP for super precision, which makes it suitable for applications where maximum precision is essential. The B.RUNNER BLOCK CS KWD-025-FNS-C1-S-1 does not include a ball chain but comes with initial lubrication and preservation to reduce maintenance needs. It also boasts a straight lube connection that is loosely attached. The overall length of the runner block is tailored to match its specific size requirements, allowing it to be interchangeable with guide rails of every accuracy level. This model excels in environments with high rigidity demands due to its excellent dynamic characteristics, reduced frictional oscillations, and low friction force levels, especially under external loads. Its patented entry zone significantly increases travel accuracy by up to six times compared to standard models. For mounting versatility, attachments can be mounted from both above and below the runner block. It also includes all-around sealing and multiple lube fittings with metal threads on all sides. The design incorporates two additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. Furthermore, the B.RUNNER BLOCK CS KWD-025-FNS-C1-S-1 supports various preload classes and can handle high torque loads while maintaining high rigidity in all load directions. This allows for single runner block applications per rail without compromising system performance. An optional integrated, inductive, wear-free measuring system can be added for enhanced functionality. Pre-lubricated at the factory, this ball runner block is compatible with all SN/SNO ball guide rails offered by Bosch Rexroth and supports long-term lubrication over several years without frequent maintenance. It maintains consistent high load ratings in all four main loading directions, ensuring reliable operation across diverse application scenarios.
