The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-P-1 (R165122220) is a ball runner block designed for precision linear motion applications. This component is part of the Ball Rail Systems product group and is characterized by its high rigidity, dynamic characteristics, and precise movement. The runner block body is made of unalloyed steel CS and features a medium preload (Preload class C) along with a precision accuracy class (P). It does not come with a ball chain but includes initial lubrication and preservation. The B.RUNNER BLOCK CS has an overall length of . mm and can be combined with guide rails of every accuracy level for versatile application. It boasts excellent dynamic characteristics, including reduced frictional oscillations and low friction levels under load. The patented entry zone enhances travel accuracy significantly, up to six times. This model is equipped with attachments that can be mounted from above or below, metal-threaded lube fittings on all sides, endface fastening threads for all attachments, and integrated all-around sealing. It offers high torque load capacity and comes in different preload classes to suit various application needs. The design also provides improved rigidity under liftoff and side loading conditions due to two additional mounting screw holes at the center of the runner block. For maximum system rigidity, it features a preloaded O-arrangement. An optional integrated, inductive, wear-free measuring system may be added. The runner block is prelubricated at the factory for long-term lubrication over several years without maintenance. It supports high load ratings in all four main loading directions and can be used on all SN/SNO ball guide rails. Additionally, this ball runner block is designed to accommodate various seals such as standard seal SS for general sealing requirements, low-friction seal LS for ease of movement requirements, double-lip seal DS for increased exposure to media, front seal for fine dirt or metal particles environments, FKM seal for extreme environments with heavy use of coolants or cutting fluids, and cover plate wiper for coarse dirt or chips environments—all interchangeable during servicing. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-P-1 (R165122220) offers precision motion capabilities suitable for applications requiring high rigidity and dynamic performance while ensuring maximum precision and longevity in harsh industrial conditions.
