The Bosch Rexroth B.RUN. BLOCK NRFG KWD-030-FNS-C2-H-0 (R200172314) is a high-precision ball runner block designed for linear motion applications requiring high accuracy and medium preload. This model is part of the NRFG series, which features a size 30 runner block made from Resist NR material, suitable for use in the packaging industry and food industry subsectors where corrosion resistance is vital. The FNS format indicates a flanged width, normal length, and standard height configuration. The runner block body and all steel components are manufactured from corrosion-resistant steel in accordance with DIN standards. It boasts an accuracy class H for high precision and a preload class C for an average preload level. This model comes without a ball chain, initial lubrication, preservation, or attachment elements on either the left or right front reference edges. It also includes a straight lube connection that is loosely attached. This Bosch Rexroth runner block has an overall length of 123 mm and offers excellent dynamic characteristics with high load ratings in all four main directions of loading. It can be used on all SNS ball guide rails and allows for long-term lubrication over several years due to its design which includes metal-threaded lube fittings on all sides. The product ensures maximum system rigidity through its preloaded O-arrangement and features end-face fastening threads for attachments. Its integrated all-around sealing along with optimized entry-zone geometry ensures minimal variation in elastic deflection while providing smooth, quiet operation. The design also includes improved rigidity under lift-off and side loading conditions via additional mounting screw holes at the center of the runner block. Overall, the B.RUN. BLOCK NRFG KWD-030-FNS-C2-H-0 (R200172314) offers limitless interchangeability within each accuracy class across all ball rail systems, making it a versatile component for various linear motion setups requiring precision and durability in challenging environments.
