The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C2-U-1 (R165182922) is a high-precision ball runner block designed for linear motion applications that demand utmost accuracy and rigidity. This runner block is part of the Ball Rail Systems product group and is made from unalloyed steel CS, featuring a size format FNS with a width flange, normal length, and standard height. It offers medium preload (class C) and ultra precision (class UP) to ensure smooth and precise movements. The B.RUNNER BLOCK CS KWD-020-FNS-C2-U-1 comes with an innovative ball chain that contributes to low noise levels and optimal travel behavior. It is prelubricated with Roller bearing grease Dynalub for maintenance-free operation over extended periods. The unit lacks attachment elements on the left front reference edge and right front reference edge but includes a straight lube connection loosely attached for easy maintenance. This model boasts high load ratings in all four main loading directions due to its robust design, which includes an integrated all-around sealing system that protects against contaminants, thus prolonging the service life of the runner block. The optimized entry zone geometry, along with a high number of balls, minimizes variations in elastic deflection, enhancing the performance under varying load conditions. For applications requiring specific torque capacities or special mounting requirements, this runner block features endface fastening threads and additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C2-U-1 can be used interchangeably with all SN/SNO ball guide rails and is capable of long-term lubrication over several years, making it an ideal choice for industries where durability and reliability are critical.
