The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-X-1 (R165122822) is a highly precise ball runner block designed for linear motion applications requiring high rigidity and precision. This runner block features a size 25 steel CS body with an FNS format, which includes a width flange, normal length, and standard height. It offers medium preload (class C) and extra precision accuracy (class XP), ensuring smooth motion and consistent performance. Equipped with a ball chain, the B.RUNNER BLOCK CS reduces noise levels and enhances travel behavior. The product comes pre-lubricated with roller bearing grease Dynalub for initial use and has provisions for long-term lubrication over several years. It boasts an integrated all-around sealing system to protect against contaminants, contributing to its longevity. The runner block's optimized entry zone geometry coupled with a high number of balls significantly reduces elastic deflection variations, thus improving travel accuracy up to six times. This feature, along with the high torque load capacity and different preload classes available, makes it suitable for applications that demand maximum precision under various load conditions. With additional mounting screw holes at the center of the runner block, users benefit from increased rigidity under lift-off and side loading conditions. The unit's design allows attachments to be mounted from both above and below, providing versatility in assembly. Furthermore, it is compatible with all SN/SNO ball guide rails from Bosch Rexroth and supports high load ratings in all four main directions of loading. For enhanced functionality, this ball runner block can optionally include an integrated inductive measuring system that is wear-free. Its dynamic load capacity C is determined based on DIN ISO standards for 100 km travel distance but can be extrapolated for shorter distances as needed. Overall, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-X-1 offers exceptional performance characteristics for demanding linear motion tasks where rigidity, precision, and durability are paramount.
