The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-CNS-C1-N-1 (R16725142Z) is a ball runner block designed for precision linear movement in various applications. This runner block is constructed from unalloyed steel CS and features a compact width, normal length, and standard height format CNS. It is engineered with a low preload class C and adheres to a standard accuracy class N, ensuring reliable operation within its specifications. The B.RUNNER BLOCK CS KWD-020-CNS-C1-N-1 does not include a ball chain but comes with initial lubrication and preservation, utilizing Roller bearing grease Dynalub for reduced maintenance needs. The design excludes attachment elements on both the left and right front reference edges while providing a straight lube connection that is loosely attached for ease of maintenance. With an overall length of the runner block specified by Bosch Rexroth, this component offers interchangeability with guide rails across all accuracy classes, allowing for flexible system integration. It is particularly suited to applications requiring high torsional moments in spaces with limited lateral availability. The runner block can handle high load ratings in all four main loading directions and supports long-term lubrication over several years. Additional features include integrated all-around sealing for protection against contaminants, improved rigidity under liftoff and side loading conditions thanks to additional center mounting screw holes, and compatibility with all BNS ball guide rails. Its design facilitates end-face fastening threads for attachments and boasts optimized entry-zone geometry that minimizes variation in elastic deflection. The preloaded O-arrangement enhances system rigidity while maintaining very high torsional moment load capacity and resistance. This product's dynamic characteristics are excellent, capable of sustaining significant torque loads. It comes pre-lubricated from the factory, ensuring readiness upon installation. Users should note the permissible ambient temperature range when operating this runner block to ensure optimal performance.
