The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-BNS-C1-P-1 (R167151220) is a high-precision ball runner block designed for linear motion systems. This component is part of the Ball Rail Systems from Bosch Rexroth and is notable for its size, accuracy, and preload specifications. The runner block body is constructed from unalloyed steel CS, ensuring durability and reliability. It features a low preload (class C) and falls within the precision accuracy class P, indicating it is suitable for applications requiring high accuracy. The B.RUNNER BLOCK CS does not incorporate a ball chain but comes with initial lubrication and preservation, using Roller bearing grease Dynalub. It has no attachment elements on either the left or right front reference edges, but includes a straight lube connection that is loosely attached. The overall length of the runner block measures at . mm. This ball runner block provides several key capabilities: it can handle high torsional moments on rails, offers the same high load ratings in all four main loading directions, supports long-term lubrication over several years, and exhibits excellent dynamic characteristics. Its design allows for attachments to be mounted from both above and below and boasts an integrated all-around sealing system to enhance its performance under various conditions. Additional features include improved rigidity under liftoff and side loading conditions due to two extra mounting screw holes at the center of the block. It's compatible with all BNS ball guide rails and comes with a wide range of accessories including an end-face fastening thread for all attachments. The optimized entry-zone geometry along with a large number of balls minimizes variation in elastic deflection, ensuring maximum system rigidity due to a preloaded O-arrangement. The R167151220 model demonstrates very high torsional moment load capacity as well as exceptional torsion resistance, making it ideally suited as an individual guide in linear motion applications. Pre-lubricated at the factory, this Bosch Rexroth ball runner block has been engineered for both efficiency in movement through low friction seals like SS standard seal or LS low-friction seal options and durability through its robust construction materials and design.
