The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C3-S-1 (R16518312Z) is a ball runner block designed for precision and rigidity in linear motion applications. This runner block features a size 20 steel CS body, with an FNS format indicating a flanged width, normal length, and standard height. It boasts a high preload class C and super precision accuracy class SP, ensuring maximum precision without the use of a ball chain. The product comes pre-lubricated with Dynalub grease for initial operation and is preserved for longevity. This runner block has no attachment elements on either the left or right front reference edges but includes straight lube connections that are loosely attached. The total length of the runner block is specified in its technical documentation. Notably, this model allows for interchangeability between the runner block and guide rails across different accuracies. The B.RUNNER BLOCK CS KWD-020-FNS-C3-S-1 is optimized for high rigidity requirements, providing excellent dynamic characteristics with reduced frictional oscillations and low friction force levels under external load conditions. Its patented entry zone increases travel accuracy significantly, up to six times. The design allows attachments to be mounted from both above and below, with metal-threaded lube fittings on all sides and end-face fastening threads for all attachments. Featuring integrated all-around sealing, this runner block can handle high torque loads across various preload classes. It's designed to maintain high rigidity even under side loading or lift-off conditions due to additional mounting screw holes at the center of the block. For systems requiring maximum rigidity, it can form a preloaded O-arrangement. An optional integrated inductive measuring system provides wear-free operation while maintaining consistent performance over time due to factory pre-lubrication. This model is compatible with all SN/SNO ball guide rails and supports long-term lubrication over several years without significant maintenance. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C3-S-1 (R16518312Z) represents a highly precise solution for applications demanding exact motion control with robust load handling capabilities in all directions of movement.
