The Bosch Rexroth B.RUNNER BLOCK CR KWD-045-FNS-C1-H-1 (R16514137Y) is a state-of-the-art linear motion guide designed for precision applications where high rigidity and accuracy are essential. This ball runner block features a Resist CR coating that enhances its corrosion resistance and durability, ensuring long-term reliability in various environments. The product boasts a size FNS format, which denotes a flange width, normal length, and standard height. It is constructed from unalloyed steel CS with a matte-silver hard chrome finish for added strength and resilience. The B.RUNNER BLOCK CR KWD-045-FNS-C1-H-1 comes with a low preload class C and high accuracy class H, making it suitable for applications that demand minimal frictional oscillations and low friction forces, especially under external loads. Its ball chain mechanism contributes to quiet operation and optimal travel behavior. Furthermore, the runner block is prelubricated at the factory with Roller bearing grease Dynalub to facilitate several years of maintenance-free operation. This product is designed to offer excellent dynamic characteristics with high load ratings in all four main loading directions. It incorporates an end-face fastening thread that allows attachments to be mounted from both above and below the runner block. The inclusion of two additional mounting screw holes at the center enhances rigidity under liftoff and side-loading conditions. Bosch Rexroth's B.RUNNER BLOCK CR KWD-045-FNS-C1-H-1 is interchangeable with guide rails of every accuracy level within its system, maximizing design flexibility. It also features various seals like the standard SS seal, low-friction LS seal, double-lip DS seal, front seal options for different environmental conditions, and additional cover plate wipers as accessories for environments with coarse dirt or chips. Overall, this ball runner block is engineered to provide maximum system rigidity due to its preloaded O-arrangement configuration across different preload classes while ensuring precise movements in demanding linear motion applications.
