The Bosch Rexroth B.RUNNER BLOCK CS KWD-030-FNS-C3-U-1 (R16517392Z) is a high-precision ball runner block designed for linear motion applications that demand ultra precision and high rigidity. This runner block is part of the Ball Rail Systems and is characterized by its size, steel CS construction, and FNS format, which denotes a width flange, normal length, and standard height. It boasts a high preload class C and an ultra precision accuracy class UP. Notable features include its lack of a ball chain, initial lubrication with preservation, and the use of roller bearing grease Dynalub. The runner block body is made from unalloyed steel CS in a standard version, while the overall length of the runner block is specified for precise applications. It offers interchangeability with guide rails of every accuracy level. The B.RUNNER BLOCK CS KWD-030-FNS-C3-U-1 excels in areas requiring high rigidity and exhibits excellent dynamic characteristics with reduced frictional oscillations even under external load. Its patented entry zone significantly increases travel accuracy by up to six times. For mounting flexibility, attachments can be added from above or below, and it includes lube fittings with metal threads on all sides as well as end-face fastening threads for various attachments. Integrated all-around sealing ensures protection against contaminants while maintaining high torque load capacity across different preload classes. The design also allows for improved rigidity under lift-off and side loading conditions thanks to additional center mounting screw holes. An optional integrated, inductive, wear-free measuring system can be fitted to enhance precision further. The ball runner block comes prelubricated from the factory for long-term lubrication over several years and is compatible with all SN/SNO Ball Guide Rails. It boasts the same high load ratings in all four main loading directions. In summary, this Bosch Rexroth ball runner block provides maximum system rigidity due to its preloaded O-arrangement suitable for applications where only one runner block per rail is permissible.
