The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FLS-C3-U-1 (R165383920) is a high precision ball runner block designed for linear motion applications requiring extreme accuracy and rigidity. This runner block is part of the FLS series, which features a flanged width, long length, and standard height. Constructed from unalloyed steel CS, it offers ultra precision (UP accuracy class) and high preload (C3 class) without the inclusion of a ball chain. The B.RUNNER BLOCK CS KWD-020-FLS-C3-U-1 is distinguished by its ability to handle demanding rigidity requirements with significantly reduced frictional oscillations and low friction levels, especially when under external load. It boasts excellent dynamic characteristics with a patented entry zone that enhances travel accuracy up to six times. The runner block is pre-lubricated and preserved for longevity, supporting long-term lubrication over several years. Featuring roller bearing grease Dynalub, this runner block has no attachment elements on either front reference edge but comes with a straight lube connection that's loosely attached. The body of the runner block has an overall length of . mm and provides interchangeability with guide rails across all accuracy classes. Designed for maximum precision, the B.RUNNER BLOCK CS KWD-020-FLS-C3-U-1 has an integrated all-around sealing system and offers high torque load capacity. It is engineered for high rigidity in all load directions, allowing usage with just one runner block per rail if necessary. Improved rigidity under liftoff and side loading conditions is achieved through additional mounting screw holes at the center of the runner block. With optional integrated inductive measuring systems available, attachments can be mounted from both above and below the runner block. Suitable for use on all SN/SNO ball guide rails, it maintains high load ratings in all four main loading directions. Pre-lubricated at the factory, this product ensures maximum system rigidity due to its preloaded O-arrangement design.
