The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-BNS-C0-H-1 (R167159322) is a high-precision ball runner block designed for use in linear guide systems. This particular model is part of the BNS series, featuring a wide width, normal length, and standard height configuration. The runner block body is constructed from unalloyed steel CS, ensuring durability and robustness for various applications. It is preloaded free (preload class C) and offers high accuracy (accuracy class H), making it suitable for applications requiring precise movement control. This ball runner block includes a ball chain which contributes to low noise levels and optimal travel behavior. It comes with initial lubrication and preservation, using Roller bearing grease Dynalub, which facilitates long-term lubrication over several years. The product boasts excellent dynamic characteristics and can handle high torsional moments on rails while providing the same high load ratings in all four main directions of loading. Attachments can be mounted from both above and below due to its versatile design, enhancing its application scope. Additional features include integrated all-around sealing to protect against contaminants, low noise emission during operation, improved rigidity under lift-off and side loading conditions through additional center mounting screw holes, and an end-face fastening thread for attachments. The runner block's optimized entry-zone geometry along with a high number of balls reduces variation in elastic deflection, ensuring maximum system rigidity when used in preloaded O-arrangements. Its quiet and smooth operation is attributed to the well-designed ball return system. In terms of technical specifications, the overall length of the runner block is specified by the manufacturer's standards. The permissible ambient temperature range for operation extends from minimum to maximum degrees Celsius, accommodating various environmental conditions. This Bosch Rexroth ball runner block model is engineered for use on all BNS ball guide rails and comes with a comprehensive range of accessories to meet diverse application needs. It stands out for its very high torsional moment load capacity and resistance to torsion, making it ideal as an individual guide in complex linear motion systems.
