The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-U-1 (R165122922) is an advanced linear motion component designed for ultra-precise applications requiring high rigidity and accuracy. This ball runner block features a size 25 profile with an FNS format, indicating a flanged width, normal length, and standard height. The runner block body is constructed from unalloyed steel CS, ensuring durability and strength. With a preload class C for medium preload and an accuracy class UP for ultra precision, this runner block delivers exceptional performance. It includes a ball chain to reduce noise levels and enhance travel behavior, while the straight lube connection ensures easy maintenance. Initial lubrication and preservation are provided from the factory with roller bearing grease Dynalub. The B.RUNNER BLOCK CS is designed without attachment elements on the front reference edges but includes end-face fastening threads for versatile mounting options. It boasts integrated all-around sealing to protect against contaminants, high torque load capacity for demanding applications, and two additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. Optimized entry zone geometry coupled with a high number of balls reduces variation in elastic deflection, enabling this runner block to achieve maximum precision even under external loads. The patented entry zone also increases travel accuracy by up to six times compared to conventional designs. This product can be used on all SN/SNO ball guide rails, offering consistent high load ratings in all four main loading directions. It's designed for long-term lubrication over several years, reducing maintenance frequency. The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-U-1 (R165122922) represents state-of-the-art linear motion technology suitable for applications where precision and rigidity are paramount.
