The Bosch Rexroth B.RUN. BLOCK NRFG KWD-020-SLS-C2-H-0 (R201282314) is a high-precision ball runner block designed for demanding applications that require smooth, quiet motion and high rigidity. This model is particularly suitable for use in the packaging industry and food industry subsectors, where its corrosion-resistant steel construction ensures durability and compliance with stringent hygiene standards. The runner block features a slimline width, long length, and standard height (SLS format), with an overall length of 63 mm. With an average preload class C and high accuracy class H, this component delivers reliable performance under medium preloading conditions while maintaining precise movement. The absence of a ball chain contributes to the block's streamlined design, and it does not include initial lubrication or preservation, giving users the flexibility to apply their preferred lubrication solution according to application needs. Designed without attachment elements on both front reference edges, the B.RUN. BLOCK NRFG allows for versatile installation options. Its straight lube connection is loosely attached for ease of maintenance. The unit boasts excellent dynamic characteristics with high load ratings in all four main loading directions, enabling use with just one runner block per rail in certain applications. This ball runner block is compatible with all SNS ball guide rails within each accuracy class, offering limitless interchangeability and maximum system rigidity due to its preloaded O-arrangement. Its integrated all-round sealing protects against contaminants while optimized entry-zone geometry ensures minimal variation in elastic deflection during operation. Furthermore, the Bosch Rexroth R201282314 provides long-term lubrication capabilities over several years thanks to its lube fittings with metal threads on all sides. Attachments can be mounted from above onto the runner block for added convenience during assembly or retrofitting processes.
