The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FLS-C1-S-1 (R165381120) is a high-precision ball runner block designed to meet the most demanding rigidity requirements in linear motion applications. This model features size E profiled rail systems and is constructed with unalloyed steel CS for durability. It boasts a low preload class C and an accuracy class SP, indicating super precision for applications requiring maximum precision. The B.RUNNER BLOCK CS KWD-020-FLS-C1-S-1 is notable for its reduced frictional oscillations and low friction force levels, especially under external loads, which contributes to its excellent dynamic characteristics. The patented entry zone increases travel accuracy by up to six times, ensuring precise movement along the guide rails. This runner block comes prelubricated with roller bearing grease Dynalub for long-term lubrication and includes integrated all-around sealing. Designed without a ball chain and attachment elements on the left or right front reference edge, this model allows for flexibility in mounting. It features end-face fastening threads for various attachments and lube fittings with metal threads on all sides. The design also includes two additional mounting screw holes at the center of the block to improve rigidity under lift-off and side loading conditions. The B.RUNNER BLOCK CS can be used with all SN/SNO ball guide rails and supports high load ratings in all four main directions of loading due to its robust construction. Its interchangeable design means it can be combined with guide rails of every accuracy level. The product also offers optional integrated, inductive, wear-free measuring systems for enhanced functionality. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FLS-C1-S-1 (R165381120) is a versatile and highly precise component suitable for linear motion systems where high rigidity, reduced friction, and long-term reliability are critical.
