The Bosch Rexroth B.RUNNER BLOCK CS KWC-055-FNS-C1-S-2 (R165151110) is a high-precision ball runner block designed for linear motion applications requiring extreme rigidity and load-bearing capacity. It features a size FNS format, which indicates a flange width, normal length, and standard height. The runner block body is made of unalloyed steel CS and boasts a super precision accuracy class (SP) with low preload class C. This model does not include a ball chain, initial lubrication, or attachment elements on the left or right front reference edges. The B.RUNNER BLOCK CS KWC-055-FNS-C1-S-2 is preserved for longevity and comes with angular lube nipples loosely attached. Its overall length is specified in the product details, and it offers interchangeability with guide rails of every accuracy level. This runner block is ideal for heavy-duty machine construction due to its high load-bearing capacity in all directions, including improved rigidity under liftoff and side loading conditions facilitated by two additional mounting screw holes at the center. Innovative channel design ensures minimum lubrication quantities are needed while providing smooth and quiet operation through optimally designed ball return and guideway systems. The optimized entry-zone geometry alongside a high number of balls reduces variation in elastic deflection. It is compatible with all SNS ball guide rails, allowing limitless interchangeability across different versions of ball guide rail systems. The product's dynamic load capacity C and torsional moment load capacity Mt are based on standard testing as per DIN ISO norms. It also features an end-face fastening thread for all attachments and can accommodate various preload classes to suit different application requirements. The runner block's design allows attachments to be mounted from both above and below, ensuring versatility in installation configurations within the applicable ambient temperature range specified in the product details.
