The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C3-S-1 (R165183122) is a high-precision ball runner block designed for linear motion applications requiring super precision and high rigidity. This runner block is part of the Ball Rail Systems product group and features a size FNS format, which includes a width flange, normal length, and standard height. The body of the runner block is made from unalloyed steel CS and it comes with a high preload class C for increased rigidity. With an accuracy class SP, this Bosch Rexroth runner block ensures maximum precision in operation. It incorporates a ball chain to reduce noise levels and enhance travel behavior. The device offers straightforward lube connections that are loosely attached, allowing for easy maintenance. Moreover, the runner block has been prelubricated at the factory with roller bearing grease Dynalub, ensuring initial lubrication and preservation. This model boasts an integrated all-around sealing system to protect against contaminants, enhancing its longevity even in harsh environments. It also has high torque load capacity and offers different preload classes to suit various application requirements. Notably, the optimized entry-zone geometry coupled with a high number of balls minimizes variation in elastic deflection. The B.RUNNER BLOCK CS KWD-020-FNS-C3-S-1 is designed to provide improved rigidity under liftoff and side loading conditions due to additional mounting screw holes at its center. Its design permits applications using just one runner block per rail while maintaining system rigidity through a preloaded O-arrangement. Suitable for all SNSSNO Ball Guide Rails, this ball runner block can handle high load ratings in all four main loading directions and allows for long-term lubrication over several years without requiring frequent maintenance. The integrated sealing system ensures that the device operates reliably even in environments with fine dirt or metal particles as well as exposure to coolants or cutting fluids.
