The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-BNS-C0-H-1 (R167159320) is a high-precision ball runner block designed for linear motion applications requiring high accuracy and torsional rigidity. This runner block features a size BNS format, which indicates a wide width, normal length, and standard height for the runner block body. Made from unalloyed steel CS, the product boasts a preload class C indicating it is preload-free, enhancing its smooth operation. The accuracy class H signifies that the runner block offers high precision in its movements. It comes without a ball chain but includes initial lubrication and preservation to ensure longevity and consistent performance. The roller bearing grease used is Dynalub, known for its quality in such applications. This model is particularly suitable for applications that experience high torsional moments on rails and require the same high load ratings in all four main loading directions. It facilitates long-term lubrication over several years and exhibits excellent dynamic characteristics due to its optimized entry-zone geometry and a high number of balls which minimize variation in elastic deflection. Furthermore, the B.RUNNER BLOCK CS KWD-020-BNS-C0-H-1 is equipped with an integrated all-around sealing system to protect against contaminants. Additional features include improved rigidity under lift-off and side loading conditions due to two extra mounting screw holes at the center of the block, compatibility with all BNS ball guide rails, a wide range of accessories options, end-face fastening threads for attachments, and lube connections with metal threads on all sides. The overall design ensures maximum system rigidity through a preloaded O-arrangement while providing very high torsional moment load capacity and resistance against twisting forces. This makes it an ideal choice as an individual guide in various linear motion setups. The product comes pre-lubricated from the factory ensuring ready-to-use delivery.
