The Bosch Rexroth B.RUNNER BLOCK CS KWC-055-FNS-C3-P-2 (R165153210) is a high-precision ball runner block designed for linear motion applications requiring high rigidity and load-bearing capacity. This runner block features a size FNS format, with a flange width, normal length, and standard height. Constructed from unalloyed steel CS, it offers a high preload class C and precision accuracy class P. Notably, it does not include a ball chain, initial lubrication, or attachment elements on the left and right front reference edges. This ball runner block is preserved for longevity and comes with angular lube nipples loosely attached. The overall length of the runner block is specified for precise installations. It has been developed for heavy-duty machine construction, providing maximum rigidity in all load directions and enhanced rigidity under liftoff and side loading conditions due to additional mounting screw holes at the center of the runner block. The design also allows attachments to be mounted from both above and below the runner block. The B.RUNNER BLOCK CS KWC-055-FNS-C3-P-2 boasts an innovative channel design that requires minimal lubrication quantities while ensuring smooth operation. The optimized ball return and guideway lead to quiet running, while the improved entry-zone geometry along with a high number of balls reduces elastic deflection variation. Furthermore, this model provides different preload classes to suit various application requirements and features end-face fastening threads for all attachments. It is compatible with all SNS ball guide rails and offers limitless interchangeability among all ball guide rail versions in combination with any ball runner block version. In terms of technical specifications, this product can withstand a wide range of ambient temperatures (minimum to maximum), has dynamic load capacity C as per DIN ISO standards, comes in various sizes for profiled rail systems (E, H, B, K, A), includes standard seals SS for protection against contaminants, offers varying degrees of friction coefficients depending on size and design specifications, has dynamic torsional moment load capacities Mt suitable for different profiled rail system sizes (H with cover strip systems), permits maximum permissible linear speeds vmax for efficient operation over distances, and supports maximum accelerations amax within specified thresholds. This Bosch Rexroth ball runner block is an ideal component for sophisticated linear motion systems where precision movement under high loads is essential.
