The Bosch Rexroth B.RUNNER BLOCK CR KWD-025-BNS-C0-H-1 (R167129372) is a ball runner block designed for high precision and corrosion resistance, featuring Resist CR coating. This runner block belongs to the BNS size category, with a wide format, normal length, and standard height. It is constructed from unalloyed steel CS with a matte-silver, hard chrome-plated finish. The preload class C indicates it is preload-free, ensuring smooth motion without pre-tensioning forces. With an accuracy class H for high precision, this runner block includes a ball chain to facilitate quiet and smooth travel behavior. It comes with initial lubrication and preservation using roller bearing grease Dynalub. The product does not include attachment elements on either the left or right front reference edges but does have a straight lube connection that is loosely attached. The overall length of the runner block is meticulously crafted to ensure compatibility with guide rails of every accuracy level within its category. This product is particularly suitable for applications requiring high torsional moments on rails, offering exceptional load ratings in all four main loading directions due to its robust design. The optimized entry-zone geometry alongside a significant number of balls reduces variation in elastic deflection, enhancing performance. The ball runner block can be utilized on all BNS ball guide rails and ensures maximum system rigidity through its preloaded O-arrangement. A wide range of accessories can be attached from above or below thanks to the end-face fastening thread provided on the runner block. To accommodate various applications and ensure longevity under different conditions, this model includes two additional mounting screw holes at its center for improved rigidity under lift-off and side loading conditions. This Bosch Rexroth ball runner block stands out for its very high torsional moment load capacity and torsion resistance making it ideal as an individual guide component in linear motion systems where precise movement and durability are crucial.
