The Bosch Rexroth B.RUNNER BLOCK CS KWD-030-FNS-C3-X-1 (R165173820) is a high-precision ball runner block designed for linear motion applications requiring exceptional accuracy and rigidity. This runner block is characterized by size CS, format FNS which indicates a flange width, normal length, and standard height. It is constructed from unalloyed steel CS and features a high preload class C and an extra precision accuracy class XP. The B.RUNNER BLOCK CS KWD-030-FNS-C3-X-1 is not equipped with a ball chain but comes with initial lubrication and preservation using Roller bearing grease Dynalub. The design facilitates attachments to be mounted from both above and below, providing flexibility in system integration. The runner block also includes metal-threaded lube fittings on all sides, and end-face fastening threads for attachments. This model boasts integrated all-around sealing for protection against contaminants and offers a high torque load capacity. It is designed to provide high rigidity in all load directions which allows for the use of just one runner block per rail in certain applications. The design also includes two additional mounting screw holes at the center of the runner block to improve rigidity under lift-off and side loading conditions. For systems requiring maximum precision, this runner block features a patented entry zone that can increase travel accuracy by up to six times. An optional integrated, inductive, wear-free measuring system can be added for precise positioning tasks. The B.RUNNER BLOCK CS KWD-030-FNS-C3-X-1 is prelubricated at the factory for convenience and supports long-term lubrication over several years. It maintains high load ratings in all four main loading directions and can be used on all SN/SNO ball guide rails from Bosch Rexroth. In summary, this ball runner block offers excellent dynamic characteristics with reduced frictional oscillations and low friction force levels, especially under external loads. Its robust construction makes it suitable for applications demanding maximum precision and rigidity.
