The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FLS-C1-S-1 (R165321120) is a ball runner block designed for super precision linear motion applications. This product features a size 25 flange long standard height (FLS) runner block body made from unalloyed steel CS, providing exceptional rigidity and durability. It has a low preload class C and an accuracy class SP, ensuring maximum precision for the most demanding tasks. The runner block does not include a ball chain, but comes with initial lubrication and preservation using Roller bearing grease Dynalub. The B.RUNNER BLOCK CS is notable for its excellent dynamic characteristics, including reduced frictional oscillations and low friction force levels, especially when under external loads. The patented entry zone enhances travel accuracy up to six times compared to standard systems. Long-term lubrication is achievable over several years due to lube fittings with metal threads on all sides. This model offers high torque load capacity and can be used in applications requiring just one runner block per rail due to its high rigidity in all load directions. Its design includes two additional mounting screw holes at the center for improved rigidity under lift-off and side loading conditions. Furthermore, it boasts maximum system rigidity thanks to a preloaded O-arrangement. Attachments can be mounted from both above and below the runner block, which is compatible with all SN/SNO ball guide rails and maintains high load ratings in all four main directions of loading. The B.RUNNER BLOCK CS comes prelubricated from the factory, ensuring ease of installation and immediate operation within permissible ambient temperatures ranging from minimum to maximum degrees Celsius as specified in the product details. With its extensive features tailored for high precision and rigidity, this ball runner block is an ideal choice for sophisticated linear motion systems that require long-term reliability and maintenance-free operation.
