The Bosch Rexroth B.RUN. BLOCK NRFG KWD-030-SNS-C2-H-0 (R201172314) is a high-precision ball runner block designed for smooth, quiet linear motion and optimized for use in environments such as the packing industry and food industry subsectors, where corrosion resistance and cleanliness are crucial. This model features a slimline width (SNS format), standard height, and normal length, made from corrosion-resistant steel in accordance with DIN standards. The runner block boasts a medium preload (class C) and high accuracy (class H), ensuring precise movement and high rigidity, which allows for the use of just one runner block per rail in certain applications. Notably, the B.RUN. BLOCK NRFG lacks a ball chain, initial lubrication, preservation, and attachment elements on both front reference edges. It includes a straight lube connection that is loosely attached. The overall length of this runner block is meticulously crafted to ensure interchangeability with guide rails of every accuracy level within its class. The product has been engineered to provide excellent dynamic characteristics with the same high load ratings in all four main directions of loading. It supports long-term lubrication over several years due to its design that includes lube fittings with metal threads on all sides. Its integrated all-around sealing and optimized entry-zone geometry result in minimal variation in elastic deflection under load. This Bosch Rexroth ball runner block also features end-face fastening threads for attachments and offers maximum system rigidity due to its preloaded O-arrangement design. The optimized design ensures smooth operation while minimizing noise—a testament to Bosch Rexroth's commitment to quality and performance in their linear motion products.
