The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-X-1 (R165121822) is a high-precision ball runner block designed for linear motion applications requiring rigidity and accuracy. This runner block is part of the Ball Rail Systems product line, specifically crafted for use in high rigidity environments with significantly reduced frictional oscillations and a low friction force level, particularly under external load. The B.RUNNER BLOCK CS features a size 25 flange width, normal length, and standard height configuration (FNS format) with an extra precision accuracy class (XP) and low preload class C. It includes a ball chain for smooth travel behavior and reduced noise levels. Constructed from unalloyed steel CS, the runner block body is robust and capable of handling high torque loads while maintaining system rigidity through a preloaded O-arrangement. Its optimized entry zone geometry, along with a high number of balls, minimizes variation in elastic deflection across all load directions. The block also features additional mounting screw holes at its center to improve rigidity under liftoff and side loading conditions. For maintenance ease, the B.RUNNER BLOCK CS comes prelubricated from the factory with roller bearing grease Dynalub. It is compatible with all SN/SNO ball guide rails and boasts high load ratings in all four main loading directions. Long-term lubrication over several years is possible due to its design. Sealing options include standard SS seals that protect against contaminants like dirt or chips without compromising movement ease. These seals are interchangeable during servicing if required by specific application needs. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-X-1 (R165121822) offers exceptional precision, durability, and versatility for various linear motion applications where maintaining maximum precision and rigidity is crucial.
