The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C3-S-1 (R165143120) is a state-of-the-art ball runner block designed for linear motion applications requiring high precision and rigidity. This model features a steel CS runner block body with dimensions tailored to the FNS format—flanged, with normal length and standard height. It is constructed to deliver super precision (accuracy class SP) without the use of a ball chain, ensuring smooth motion and reduced frictional oscillations even under external loads. The B.RUNNER BLOCK CS KWD-045-FNS-C3-S-1 is preloaded to a high preload class C, which contributes to its excellent dynamic characteristics and maximum precision. The patented entry zone of the runner block significantly increases travel accuracy by up to six times compared to standard models. Designed for ease of use, attachments can be mounted from both above and below the block, with metal-threaded lube fittings on all sides and an end-face fastening thread for additional attachments. This model boasts an integrated all-around sealing system that provides protection against contaminants, thereby extending the service life of the unit. The high torque load capacity coupled with different preload classes allows for versatile application across various demands. The added mounting screw holes at the center enhance rigidity under lift-off and side loading conditions. For applications requiring exact measurements, an optional integrated, inductive, and wear-free measuring system is available. The B.RUNNER BLOCK comes prelubricated from the factory for immediate use and supports long-term lubrication over several years without maintenance. It maintains high load ratings in all four main directions of loading due to its robust design. Compatible with all SN/SNO ball guide rails, this Bosch Rexroth ball runner block is suitable for applications where high rigidity requirements are essential along with superior dynamic performance and minimal frictional forces. Its design ensures that it can function effectively as a single runner block per rail in certain scenarios while still providing maximum system rigidity when used in an O-arrangement setup.
