The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C1-N-2 (R165121424) is a state-of-the-art ball runner block designed for high-performance linear motion applications. This product is part of Bosch Rexroth's Ball Rail Systems, known for their precision and durability. Constructed to DIN standards, the runner block features a four-row ball design that ensures point contact in every loading direction, significantly reducing friction and minimizing heat generation compared to other systems with gothic raceway profiles. This model boasts exceptional sealing capabilities with standard universal seals (SS) that provide consistent protection for guide rails with or without cover strips. For environments requiring lower friction or enhanced sealing against media exposure, options such as the low-friction seal (LS), double-lip seal (DS), and FKM seal are available, each tailored to specific operational needs. The front seal option offers additional protection in environments laden with fine dirt, metal particles, coolants, or cutting fluids. Cover plate wipers can be utilized in areas with coarse contaminants. The B.RUNNER BLOCK CS KWD-025-FNS-C1-N-2 is designed for versatility and ease of maintenance; seals and cover plate wipers are interchangeable during servicing. It allows attachments to be mounted from both above and below, featuring lube fittings with metal threads on all sides for simplified lubrication management. The end-face fastening thread accommodates various attachments while its integrated all-around sealing ensures longevity under harsh conditions. With high torque capacity and different preload classes available, this runner block achieves high rigidity in all load directions allowing for single-block applications per rail. Enhanced rigidity under liftoff and side-loading conditions is achieved via additional mounting screw holes at the center of the block. For systems requiring maximum rigidity, a pretensioned O-arrangement is an option. Furthermore, an optional integrated inductive measuring system offers wear-free operation for precise positioning tasks. The B.RUNNER BLOCK comes pre-lubricated from the factory, supporting long-term lubrication over several years without maintenance. It also provides uniform load ratings across all four main loading directions ensuring reliable performance regardless of application orientation.
