The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C1-U-1 (R165181922) is a ball runner block designed for ultra-precision linear motion applications. This runner block features size CS steel construction with a low preload class C and an accuracy class UP, indicating its ultra-precise capabilities. It is equipped with a ball chain to ensure smooth movement and reduced noise levels, and it comes pre-lubricated with roller bearing grease Dynalub for initial use. The product has an overall length of . mm and boasts high rigidity requirements, making it suitable for applications that demand minimal frictional oscillations and low friction force levels, especially under external loads. The patented entry zone of the runner block enhances travel accuracy up to six times compared to standard blocks. It has been designed for easy attachment both from above and below without requiring left or right front reference edge attachment elements. This model offers high torque load capacity, various preload classes, optimized entry zone geometry, and a significant number of balls to minimize variation in elastic deflection. Its design allows for improved rigidity under liftoff and side loading conditions due to additional mounting screw holes at the center of the block. The B.RUNNER BLOCK CS KWD-020-FNS-C1-U-1 can be used on all SN/SNO ball guide rails, maintaining high load ratings in all main directions of loading. Long-term lubrication over several years is possible due to its design features. It also includes integrated all-round sealing for protection against contaminants. Optional features include an integrated inductive measuring system that is wear-free. The product's versatility allows it to be used in various configurations while maintaining maximum system rigidity due to its preloaded O-arrangement. The Bosch Rexroth runner block is interchangeable with guide rails across different accuracies, further enhancing its adaptability for precision-driven industrial uses.
