The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FLS-C2-U-1 (R16538292Z) is a high-precision ball runner block designed for linear motion applications requiring ultra precision and medium preload. This runner block is part of the Ball Rail Systems product group, which emphasizes reduced frictional oscillations and low friction levels, especially under external loads. The B.RUNNER BLOCK CS features an overall length of 20 mm, a width flange, and a standard height format FLS. It is made from unalloyed steel CS and falls into the accuracy class UP (Ultra Precision), ensuring maximum travel accuracy. This model does not include a ball chain and comes with initial lubrication and preservation using Roller bearing grease Dynalub. The runner block body is in its standard version, without attachment elements on either front reference edge, but it does include a straight lube connection loosely attached. It boasts high rigidity in all load directions, allowing it to be used with just one runner block per rail for certain applications. The B.RUNNER BLOCK CS offers improved rigidity under liftoff and side loading conditions due to additional mounting screw holes at its center. Its design also allows for maximum system rigidity through a preloaded O-arrangement. An optional integrated inductive measuring system can be added for wear-free measurement capabilities. This ball runner block can be paired with all SN/SNO ball guide rails and maintains high load ratings in all four main directions of loading. Pre-lubricated at the factory, it supports long-term lubrication over several years and features lube fittings with metal threads on all sides for maintenance ease. With end-face fastening thread available for attachments, this Bosch Rexroth runner block is versatile in its application scope. It also includes integrated all-around sealing to protect against contaminants, ensuring longevity and consistent performance in diverse operating environments.
