The Bosch Rexroth B.RUNNER BLOCK CR KWD-020-CNS-C0-H-1 (R167259370) is a state-of-the-art ball runner block designed for high-precision and corrosion-resistant applications. It features a Resist CR coating that ensures durability and protection against corrosive elements. The product is defined by its compact width, normal length, and standard height, aligning with the CNS format. Constructed from unalloyed steel CS with a matte silver finish and hard chrome plating, this runner block body guarantees high accuracy (class H) and is preload-free (class C). This model does not include a ball chain but comes with initial lubrication and preservation using Roller bearing grease Dynalub to ensure smooth operation from the outset. The runner block has an overall length of . mm and offers excellent dynamic characteristics, capable of handling high torsional moments on rails where lateral space may be limited. It boasts impressive load ratings in all four main directions of loading, contributing to its versatility. The B.RUNNER BLOCK CR is also designed for maximum system rigidity thanks to its preloaded O-arrangement, with attachments that can be mounted from above using an end-face fastening thread. Its optimized entry-zone geometry and numerous balls reduce elastic deflection variation, enhancing performance consistency. This model can be used on all BNS ball guide rails and comes equipped with a wide range of accessories. Notably, the ball runner block has improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at its center. With very high torsional moment load capacity and exceptional torsion resistance, it's primarily utilized as an individual guide in material profiled rail systems. The Bosch Rexroth B.RUNNER BLOCK CR KWD-020-CNS-C0-H-1 (R167259370) represents an advanced solution for linear motion applications requiring precision, durability, and adaptability in challenging environments.
