The Bosch Rexroth B.RUNNER BLOCK AL KWD-025-FNS-C1-N-1 (R163121421) is a high-precision aluminum ball runner block designed for use in various industrial applications. This component is notable for its lightweight design, made possible by its aluminum construction, which offers a reduced weight compared to steel versions without compromising on precision or load capacity. The runner block features a size FNS format, indicating a flange width, normal length, and standard height. It is part of the standard accuracy class N and has a low preload class C. This ball runner block does not include a ball chain but comes with initial lubrication and preservation for immediate use. It boasts an optimized entry zone geometry and a high number of balls to minimize variation in elastic deflection. The design also includes an extracompact form factor which contributes to less gravity impact due to the lighter material. The patented entry zone significantly increases travel accuracy by up to six times. The B.RUNNER BLOCK AL KWD-025-FNS-C1-N-1 is compatible with all SNS ball guide rails and features lube connections with metal threads on all sides for ease of maintenance. Its design includes additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. Attachments can be mounted from both above and below the runner block, providing flexibility in assembly. This runner block supports limitless interchangeability within each accuracy class, meaning it can be combined with any ball guide rail system within its class. It comes prelubricated from the factory and includes an integrated reservoir for oil lubrication, ensuring long-term maintenance-free operation. Additionally, it has predesigned holes for pinned fitting that enable greater parallelism and height offsets of mounting bases. In summary, the Bosch Rexroth B.RUNNER BLOCK AL KWD-025-FNS-C1-N-1 (R163121421) offers maximum precision in a lightweight package suitable for dynamic applications where high load capacity, reduced weight, and long-term reliability are essential.
