The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FLS-C2-P-1 (R165382220) is a high-precision ball runner block designed with a focus on rigidity and dynamic performance. This runner block features a size 20 flange, long-length standard height format (FLS), and is constructed from unalloyed steel CS for durability. It is classified under preload class C, indicating a medium preload, and accuracy class P for precision applications. The product does not include a ball chain but comes with initial lubrication and preservation. It uses Roller bearing grease Dynalub for smooth operation. The runner block body is in the standard version, with an overall length specified for the model. It also boasts interchangeability features, meaning it can be combined with guide rails of every accuracy level. This Bosch Rexroth runner block is engineered to meet the most demanding rigidity requirements, significantly reducing frictional oscillations and maintaining low friction levels even under external load conditions. Its excellent dynamic characteristics are further enhanced by a patented entry zone that can increase travel accuracy by up to six times. Designed for long-term lubrication that could extend over several years, it includes lube fittings with metal threads on all sides and an end-face fastening thread for all attachments. The integrated all-around sealing ensures protection against contaminants, contributing to its high torque load capacity. Different preload classes are available to suit various application needs alongside high rigidity in all load directions, which allows the use of just one runner block per rail in some cases. The design also includes additional mounting screw holes at the center of the block to improve rigidity under lift-off and side loading conditions. This model offers maximum system rigidity due to its preloaded O-arrangement and optional integrated, inductive, wear-free measuring systems. Attachments can be mounted from both above and below the runner block, ensuring versatility in assembly. It is compatible with all SN/SNO ball guide rails while maintaining high load ratings in all four main directions of loading. Pre-lubricated at the factory for immediate use upon delivery, this Bosch Rexroth ball runner block represents an optimal solution for various linear motion applications where precision and reliability are paramount.
