The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-BNS-C1-N-1 (R167121420) is a high-precision ball runner block designed for linear motion applications. This product features a steel CS runner block body with a standard accuracy class N and a low preload class C, ensuring smooth and accurate movement without the presence of a ball chain. The runner block's dimensions are tailored to provide wide width, normal length, and standard height, making it suitable for various industrial uses. The B.RUNNER BLOCK CS is characterized by its ability to handle high torsional moments on rails and maintain high load ratings in all four main loading directions. It is engineered for long-term lubrication over several years, demonstrating excellent dynamic characteristics that contribute to its overall performance. Notably, this model allows for attachments to be mounted from both above and below the block. An integrated all-around sealing system enhances the rigidity under lift-off and side loading conditions, partly due to additional mounting screw holes at the center of the block. The product is compatible with all BNS ball guide rails and offers a wide range of accessory options. It features an end-face fastening thread for various attachments and a straight lube connection with metal threads on all sides. The optimized entry-zone geometry combined with a high number of balls reduces variation in elastic deflection, maximizing system rigidity due to its preloaded O-arrangement. The Bosch Rexroth B.RUNNER BLOCK CS is known for its very high torsional moment load capacity and resistance to torsion, making it an ideal choice as an individual guide in demanding environments. Pre-lubricated at the factory, this ball runner block ensures reliable performance right from installation. This product also boasts improved sealing capabilities with options such as standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper available as accessories for specific environmental requirements. Its design ensures interchangeability during servicing while providing maximum protection against contaminants that could reduce service life.
