The Bosch Rexroth B.RUN. BLOCK NRFG KWD-030-SLS-C1-H-0 (R201271314) is a high-precision ball runner block designed for demanding linear motion applications. This model features a slimline width, long length, and standard height (SLS format), ensuring a compact footprint while maintaining robust performance. The runner block body and all steel components are constructed from corrosion-resistant steel in accordance with DIN standards, which makes it particularly suitable for use in environments like the packaging and food industry sectors where cleanliness and resistance to harsh conditions are paramount. This ball runner block boasts a low preload class C, indicating minimal rolling resistance and smooth movement under low load conditions. It is also classified under accuracy class H for high precision, making it ideal for applications that require exact positioning and repeatability. The product does not include a ball chain, preservation, or initial lubrication, allowing users to customize these aspects to their specific requirements. With an overall length of 123 mm and the ability to be used on all SNS ball guide rails, this model offers excellent dynamic characteristics with high load ratings in all four main loading directions. It supports long-term lubrication capabilities over several years due to its lube fittings with metal threads on all sides. The interchangeability feature ensures that the runner block can be combined with guide rails of every accuracy level without compatibility issues. The B.RUN. BLOCK NRFG KWD-030-SLS-C1-H-0 is designed to provide maximum system rigidity through its preloaded O-arrangement and offers end-face fastening threads for various attachments. Its integrated all-around sealing, optimized entry-zone geometry, and high number of balls contribute to reduced elastic deflection variation and quiet operation. Attachments can be conveniently mounted from above the runner block for ease of installation. In summary, this Bosch Rexroth ball runner block is engineered for superior performance in linear motion systems where precision, durability, and interchangeability are critical factors.
