The Bosch Rexroth B.RUNNER BLOCK AL KWD-030-FNS-C1-N-1 (R163171422) is a high-precision aluminum ball runner block designed for linear motion applications requiring reduced weight without sacrificing accuracy or load capacity. This runner block is part of the Ball Rail Systems product line and features a size 30 profile with an FNS format, indicating a flanged width, normal length, and standard height. The aluminum construction offers an extracompact lightweight design, providing less gravity impact compared to steel blocks. The B.RUNNER BLOCK AL KWD-030-FNS-C1-N-1 comes with a low preload (Preload class C) and standard accuracy (Accuracy class N), ensuring smooth operation with minimal variation in elastic deflection. It includes a ball chain for quiet travel behavior and is pre-lubricated at the factory with roller bearing grease Dynalub for long-term maintenance-free operation. Designed for versatility, the runner block allows attachments to be mounted from both above and below, enhancing design flexibility. It also features two additional mounting screw holes at the center for improved rigidity under various loading conditions. The optimized entry zone geometry and high number of balls contribute to maximum precision and torque load capacity while minimizing noise levels. This model is interchangeable with guide rails in every accuracy class, making it suitable for diverse industrial applications where lightweight designs are essential or where low tolerances need compensation in connected structures. The predrilled holes on the runner block enable precise fitting and greater parallelism when mounting. Sealing options like the standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper are available to protect against contaminants that may reduce service life. These seals ensure that the Bosch Rexroth B.RUNNER BLOCK AL can operate effectively even in harsh environments while maintaining ease of movement and effective sealing against external elements.
