The Bosch Rexroth B.RUNNER BLOCK CS KWD-015-FNS-C2-X-1 (R165112820) is a high-precision ball runner block designed for dynamic and high rigidity applications. This model features a size FNS format, indicating a width with flange, normal length, and standard height. It is constructed from unalloyed steel CS and comes without a ball chain. The runner block body is preloaded in class C for medium preload and boasts an extra precision accuracy class XP. It is initially lubricated with roller bearing grease Dynalub and does not include attachment elements on either the left or right front reference edges. The B.RUNNER BLOCK CS offers excellent dynamic characteristics, with significantly reduced frictional oscillations and low friction levels under external loads. The patented entry zone enhances travel accuracy by up to six times. The runner block can be attached from both above and below, featuring lube fittings with metal threads on all sides and an endface fastening thread for attachments. It also includes integrated all-around sealing for protection against contaminants. This model supports high torque load capacity across various preload classes and maintains high rigidity in all load directions, allowing for the use of just one runner block per rail if needed. Additional mounting screw holes at the center of the runner block improve rigidity under liftoff and side loading conditions. An optional feature includes an integrated, inductive, wear-free measuring system. The B.RUNNER BLOCK CS comes prelubricated from the factory for immediate use on all SNSSNO ball guide rails. It offers long-term lubrication capabilities spanning several years without the need for maintenance. With its design focused on maximum system rigidity due to a preloaded O-arrangement, this ball runner block can handle high load ratings in all four main loading directions, making it suitable for diverse applications requiring precision movement and reliability.
