The Bosch Rexroth B.RUNNER BLOCK CS KWC-055-FNS-C0-N-2 (R165159410) is a state-of-the-art ball runner block designed for high rigidity applications and heavy machine construction. This component boasts an impressive load-bearing capacity, ensuring maximum rigidity in all directions, even under liftoff and side loading conditions due to the inclusion of two additional mounting screw holes at the center. The runner block body is constructed from unalloyed steel CS and comes without a ball chain, preserved but without initial lubrication. This model features a standard accuracy class N and is preload class C, indicating it is preload-free. It has an angular lube nipple loosely attached for ease of maintenance. The B.RUNNER BLOCK CS KWC-055-FNS-C0-N-2 offers smooth and quiet operation with its optimally designed ball return and guideway system. With innovative channel design, it requires minimal lubrication quantities. Furthermore, this ball runner block can be used on all SNS ball guide rails, providing limitless interchangeability across various guide rail versions. The entry zone geometry has been optimized alongside a high number of balls to reduce variation in elastic deflection. Attachments can be mounted from both above and below the block, with end-face fastening threads available for all attachments. The Bosch Rexroth B.RUNNER BLOCK CS KWC-055-FNS-C0-N-2 is self-aligning to compensate for any misalignments and comes without self-alignment ball chain as standard. It offers dynamic load capacity and torsional moment load capacities that are calculated based on a 100,000 m travel as per DIN ISO standards. The product also includes various sealing options like standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper to protect against contaminants that could reduce service life. In summary, this Bosch Rexroth ball runner block represents a robust solution for demanding linear motion applications requiring high precision and durability along with ease of maintenance and versatile compatibility with guide rails.
