The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C1-N-1 (R16518142Y) is a state-of-the-art ball runner block designed for linear motion applications requiring high rigidity and precision. This component features an unalloyed steel CS body and is part of the FNS series, indicating a flange width, normal length, and standard height. It comes with a low preload class C and a standard accuracy class N. The ball runner block is equipped with a ball chain that ensures low noise levels and optimal travel behavior. The B.RUNNER BLOCK CS KWD-020-FNS-C1-N-1 is notable for its high torque load capacity and the ability to minimize variation in elastic deflection due to its optimized entry zone geometry and numerous balls. Its design allows for applications using only one runner block per rail, improving system rigidity. Additionally, it features two extra mounting screw holes at the center for enhanced rigidity under liftoff and side loading conditions. This model provides maximum precision with significantly reduced frictional oscillations and low friction force levels, especially under external loads. Its patented entry zone can increase travel accuracy up to six times compared to other systems. The runner block is prelubricated at the factory with roller bearing grease Dynalub, ensuring long-term lubrication over several years. Bosch Rexroth's B.RUNNER BLOCK CS KWD-020-FNS-C1-N-1 can be used on all SN/SNO ball guide rails and offers high load ratings in all four main directions of loading. For applications demanding an integrated measuring system, this runner block has optional provisions for an inductive, wear-free measuring system. Its dynamic load capacity C and static longitudinal moment load capacity ML are determined based on DIN ISO standards. With its comprehensive sealing options including standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper—this ball runner block can withstand various environmental conditions while preventing contaminants from affecting its performance.
