The Bosch Rexroth B.RUNNER BLOCK CS KWC-055-FNS-C2-S-2 (R165152110) is a high-precision ball runner block designed for heavy-duty applications that require maximum rigidity and load-bearing capacity. This runner block is part of the Ball Rail Systems product group and is notable for its size, format FNS—flange width, normal length, and standard height. It is constructed from unalloyed steel CS and offers super precision (accuracy class SP) without a ball chain, ensuring smooth and quiet operation. The B.RUNNER BLOCK CS features an average preload (preload class C), which contributes to its medium preload characteristics. It is preserved but comes without initial lubrication, allowing users to select the most appropriate lubrication for their specific application. The angular lube nipples are loosely attached to facilitate easy maintenance. This model boasts an overall length of . mm and can accommodate high torque loads due to its robust design, which includes additional mounting screw holes at the center for improved rigidity under liftoff and side loading conditions. The optimized entry zone geometry alongside a high number of balls reduces variation in elastic deflection. The B.RUNNER BLOCK CS is versatile with end-face fastening threads for attachments, which can be mounted from both above and below the block. It can be used with all SNS Ball Guide Rails, offering limitless interchangeability across different guide rail versions. Its innovative channel design minimizes lubrication requirements while maintaining smooth operation. In terms of technical specifications, this runner block has a static load rating C0 and dynamic load capacity C1 that are determined based on DIN ISO standards with a nominal size fitting into Size H profiled rail systems. The friction coefficient ranges between . , ensuring efficient movement with minimal resistance. Overall, the Bosch Rexroth B.RUNNER BLOCK CS KWC-055-FNS-C2-S-2 (R165152110) offers superior performance in demanding environments where precision movement and high-load capabilities are essential.
