The Bosch Rexroth B.RUNNER BLOCK CS KWD-035-FNS-C2-S-1 (R16513212Z) is a ball runner block designed for high rigidity and precision linear movement applications. This component is part of the Ball Rail Systems product group, specifically tailored for use in systems that require precise guidance and smooth motion. The runner block body is made from unalloyed steel CS, ensuring durability and stability. This model features a size E profile with a flanged, normal, standard height format (FNS), and boasts super precision accuracy (SP) without a ball chain. It comes with a medium preload class C, indicative of its average preload capacity which contributes to the runner block's consistent performance. The overall length of the runner block is optimized to fit within its designated rail system. The B.RUNNER BLOCK CS KWD-035-FNS-C2-S-1 is notable for its dynamic characteristics and ability to significantly reduce frictional oscillations even under external loads. It achieves maximum precision thanks to a patented entry zone that enhances travel accuracy by up to six times compared to conventional designs. Designed with versatility in mind, attachments on this ball runner block can be mounted from both above and below, offering flexibility in assembly and maintenance. It features lube fittings with metal threads on all sides and an endface fastening thread for securing various attachments. Its integrated all-around sealing provides protection against contaminants, thereby extending service life. High torque load capacity, multiple preload classes, and exceptional rigidity in all load directions enable this runner block to perform reliably even when used as a single unit per rail. The two additional mounting screw holes at the center further enhance rigidity under liftoff and side loading conditions. An optional integrated, inductive, wear-free measuring system can be included for precise position feedback. Pre-lubricated at the factory for immediate use upon delivery, it can operate on all SN/SNO ball guide rails and supports long-term lubrication over several years without requiring frequent maintenance. This Bosch Rexroth ball runner block is engineered to withstand high load ratings in all four main directions of loading while maintaining consistent performance across a permissible ambient temperature range from minimums to maximums as specified by the manufacturer's guidelines. Its design facilitates self-alignment capabilities which are crucial for compensating misalignments during operation.
