The Bosch Rexroth B.RUNNER BLOCK CS KWD-030-FNS-C2-U-1 (R165172920) is a highly precise ball runner block designed for linear motion applications requiring high rigidity and precision. This runner block features a size 30, FNS format with medium preload class C and ultra precision accuracy class UP, suitable for demanding tasks where exact movement is critical. The body of the runner block is made from unalloyed steel CS, ensuring durability and strength. This model does not include a ball chain but comes with initial lubrication and preservation for ease of maintenance. It also boasts an innovative design that reduces frictional oscillations and maintains low friction levels even under external load, enhancing its dynamic characteristics. The patented entry zone significantly improves travel accuracy by up to six times compared to standard models. The B.RUNNER BLOCK CS KWD-030-FNS-C2-U-1 is versatile, allowing attachments to be mounted from both above and below. It features metal-threaded lube fittings on all sides and end-face fastening threads for various attachments. An integrated all-around sealing system offers protection against contaminants, contributing to the runner block's longevity. High torque load capacity, different preload classes, and high rigidity in all load directions enable this runner block to function optimally with just one unit per rail if necessary. Two additional mounting screw holes at the center enhance rigidity under lift-off and side loading conditions. The potential integration of an inductive measuring system provides wear-free operation and precise measurements. Pre-lubricated at the factory for immediate use, it is compatible with all SN/SNO ball guide rails from Bosch Rexroth. Long-term lubrication capabilities extend over several years without frequent maintenance needs. It supports high load ratings in four main directions of loading and can withstand various environmental conditions within permissible temperature ranges.
