The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-N-1 (R16512142Z) is a high-precision ball runner block designed for linear motion applications requiring rigidity and precision. This runner block belongs to the FNS format, which indicates a width flange, normal length, and standard height. It is crafted from unalloyed steel CS and features a low preload (class C) and standard accuracy (class N). Notably, this model does not include a ball chain but comes with initial lubrication and preservation. The product boasts an overall length of . mm, with the capability to interchangeably combine with guide rails of every accuracy class. Its design ensures excellent dynamic characteristics, with significantly reduced frictional oscillations and low friction force levels, especially under external load conditions. The patented entry zone enhances travel accuracy by up to six times. This model allows for attachments on the runner block from both above and below, with lube fittings featuring metal threads on all sides. It also includes an end-face fastening thread for all attachments. The integrated all-around sealing contributes to its high torque load capacity. With different preload classes available, it can achieve high rigidity in all load directions, allowing for use with just one runner block per rail. Additional features include improved rigidity under liftoff and side loading conditions due to two extra mounting screw holes at the center of the block. For maximum system rigidity, it uses a preloaded O-arrangement. An optional integrated inductive and wear-free measuring system is available as well. The B.RUNNER BLOCK CS KWD-025-FNS-C1-N-1 is prelubricated at the factory for long-term lubrication over several years. It maintains high load ratings in all four main directions of loading and can be utilized on all SN/SNO ball guide rails. The unit's robust design ensures it meets the demands of various applications while providing maximum precision and performance longevity.
