The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FLS-C2-X-1 (R165342820) is a high-precision ball runner block designed for linear motion applications that require exceptional rigidity and accuracy. This product features a flanged, long, and standard height (FLS) format with a body made of unalloyed steel CS. It is classified under preload class C, indicating a medium preload, and accuracy class XP for extra precision. The runner block does not incorporate a ball chain and comes prelubricated with roller bearing grease Dynalub, ensuring long-term lubrication over several years. The B.RUNNER BLOCK CS boasts an overall length of . mm, with the ability to interchangeably combine with guide rails of every accuracy to meet the most rigorous rigidity demands. Its design significantly reduces frictional oscillations while maintaining low friction levels, even under external loads. This leads to excellent dynamic characteristics and maximum precision in operation. With its patented entry zone, the travel accuracy of this runner block can be increased up to six times compared to standard blocks. It also features high torque load capacity across different preload classes and provides high rigidity in all load directions—enabling applications to function with just one runner block per rail if necessary. Additional design benefits include improved rigidity under lift-off and side loading conditions due to two extra mounting screw holes at the center of the block. The system's overall rigidity is maximized by a preloaded O-arrangement. For versatility in installation, attachments on the ball runner block can be mounted from both above and below. The B.RUNNER BLOCK CS is compatible with all SN/SNO ball guide rails and maintains high load ratings in all four main loading directions. Sealing options such as standard seal SS or low-friction seal LS are available for protection against contaminants like dirt or chips—ensuring reliable operation even in harsh environments. Optional accessories like front seals or cover plate wipers can be added during servicing for enhanced protection against specific environmental challenges.
