The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C1-N-1 (R165181421) is a high-precision ball runner block designed for linear motion applications requiring high rigidity and precise movement. This runner block features a size 20 profile with a flange width, standard length, and height in the FNS format. It is constructed from unalloyed steel CS and provides a low preload (class C) with standard accuracy (class N). Notably, it does not include a ball chain but comes with initial lubrication and preservation for immediate use. The B.RUNNER BLOCK CS boasts excellent dynamic characteristics with reduced frictional oscillations and low friction levels, especially under external load conditions. Its patented entry zone significantly enhances travel accuracy by up to six times. The design allows attachments to be mounted from both above and below the block, offering flexibility in system integration. Lube fittings are conveniently placed on all sides with metal threads, facilitating easy maintenance. One of the standout features of this runner block is its integrated all-around sealing system that ensures high durability even in demanding environments. It offers various preload classes to suit different application needs and maintains high rigidity in all loading directions. This rigidity is further improved under liftoff and side-loading conditions due to additional mounting screw holes located at the center of the block. For systems requiring precise measurement, an optional integrated, inductive, and wear-free measuring system can be included. Pre-lubricated at the factory, the B.RUNNER BLOCK CS is compatible with all SN/SNO ball guide rails from Bosch Rexroth, supporting long-term lubrication over several years without needing frequent maintenance. With its ability to withstand high load ratings in all four main directions of loading, this runner block caters to applications where maximum precision and reliability are paramount.
