The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C0-N-1 (R165149422) is a high-precision ball runner block designed for linear motion systems that require high rigidity and precision. This model is part of the Ball Rail Systems product line, crafted for a variety of applications where reduced frictional oscillations and low friction force levels are critical, especially under external loads. Its optimized entry zone geometry and a high number of balls ensure minimal variation in elastic deflection, offering maximum travel accuracy. The runner block body is made of unalloyed steel CS, featuring a standard height, flange width, and normal length format (FNS). It comes with standard accuracy class N and is preload-free (preload class C), meaning there's no initial tension between the block and the rail which can be beneficial for certain applications. The ball chain included contributes to a reduced noise level and optimal travel behavior. This runner block is also equipped with all-around sealing to protect against contaminants, enhancing its longevity even in harsh environments. The design includes lube fittings with metal threads on all sides for easy maintenance and lubrication. For enhanced versatility, it has an end-face fastening thread for various attachments. Notably, this model boasts high load ratings in all four main loading directions due to its robust construction. It's designed to work seamlessly with all SN/SNO ball guide rails from Bosch Rexroth. The B.RUNNER BLOCK CS KWD-045-FNS-C0-N-1 comes prelubricated from the factory for immediate use and offers the possibility of long-term lubrication over several years. In terms of installation flexibility, this runner block can be used singularly per rail thanks to its high rigidity which allows it to withstand liftoff and side loading conditions effectively. Additional mounting screw holes at the center enhance this capability further. Optional features include an integrated inductive measuring system that provides wear-free operation for precise positioning tasks without additional sensors or components.
