The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C0-N-1 (R165189420) is a state-of-the-art ball runner block designed for high rigidity applications and exceptional dynamic characteristics. This product is notable for its size E profiled rail systems compatibility, featuring a flange width, standard length, and height format FNS. The runner block body is constructed from unalloyed steel CS, ensuring durability and longevity. It offers standard accuracy class N and is preload class C, indicating that it is preload-free. Notably absent is the ball chain, emphasizing its streamlined design. The B.RUNNER BLOCK CS KWD-020-FNS-C0-N-1 excels in reducing frictional oscillations and maintaining a low friction force level even under external load due to its innovative entry zone that enhances travel accuracy by up to six times. Attachments can be conveniently mounted from both above and below the runner block, with lube fittings featuring metal threads on all sides for ease of maintenance. The product boasts an integrated all-around sealing system to protect against contaminants and ensure long-term operation. With high torque load capacity and the option for different preload classes, this runner block can be utilized effectively with just one unit per rail in certain applications. Its design includes additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. The possibility of integrating an inductive, wear-free measuring system adds to its versatility. Pre-lubricated at the factory with roller bearing grease Dynalub for initial use, this ball runner block promises long-term lubrication capabilities spanning several years without the need for frequent maintenance. It's engineered to handle high load ratings consistently across all four main directions of loading. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C0-N-1 (R165189420) offers maximum precision and flexibility for demanding linear motion applications while ensuring easy installation, minimal maintenance requirements, and robust performance over time.
