The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C1-S-1 (R165181122) is a high-precision ball runner block designed for linear motion applications that require superior accuracy and rigidity. This runner block features an FNS format, indicating its width, length, and height are flanged, normal, and standard respectively. The body of the runner block is constructed from unalloyed steel CS and is preloaded to class C for low preload. It boasts an accuracy class SP for super precision. The runner block is equipped with a ball chain that ensures low noise operation and optimal travel behavior. It comes with initial lubrication and preservation for immediate use upon installation. The B.RUNNER BLOCK CS has straight lube connections loosely attached and does not include attachment elements on either the left or right front reference edge. This model has been engineered to meet high rigidity requirements, significantly reducing frictional oscillations and maintaining a low friction force level even under external loads. Its patented entry zone amplifies travel accuracy by up to six times compared to standard models. The design allows attachments to be mounted from both above and below the block, while all-around sealing provides protection against contaminants. Furthermore, the B.RUNNER BLOCK CS supports high torque loads and offers various preload classes to suit different application needs. The optimized entry zone geometry along with a high number of balls minimizes elastic deflection variation. The product also features improved rigidity under liftoff and side loading conditions due to two additional mounting screw holes at the center of the block. This Bosch Rexroth runner block can be utilized with all SNSSNO ball guide rails, offering consistent high load ratings in all four main loading directions. Long-term lubrication capabilities extend over several years without the need for maintenance, ensuring reliable operation over an extended period.
