The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FKS-C1-N-2 (R166581424) is a high-performance ball runner block designed for precision linear movement and guidance. This product is part of Bosch Rexroth's Ball Rail Systems, crafted to meet DIN standards for linear guides. The runner block boasts a unique four-row ball design that ensures point contact in all loading directions, minimizing friction and heat generation. This feature provides smoother motion and extends the service life of the component. The R166581424 is equipped with universal standard seals (SS) that deliver both low friction and effective sealing on guide rails with or without cover strips, making it suitable for a variety of applications. For environments requiring minimal resistance to movement, the low-friction seal (LS) is ideal, while the double-lip seal (DS) offers enhanced protection against harsh media exposure. Front seals are also available for added defense against fine dirt or metal particles and can be easily exchanged during servicing. For extreme conditions involving heavy coolants or cutting fluids usage, FKM seals are an option that can also be replaced by the customer when necessary. Additionally, cover plate wipers can be installed to protect against coarse dirt or chips. The runner block enables long-term lubrication over several years, reducing maintenance requirements. Noteworthy features include lube fittings with metal threads on all sides, end-face fastening threads for various attachments, integrated all-around sealing, high torque capacity, and different preload classes. The R166581424 demonstrates high rigidity in all load directions which allows for applications using just one runner block per rail while maintaining the same high load ratings in all four main loading directions. Furthermore, this model offers maximum system rigidity due to its pretensioned O-arrangement and optional integrated inductive measuring system for precise positioning tasks. Its excellent dynamic characteristics make it suitable for applications demanding high-speed movement without sacrificing accuracy or durability.
