The Bosch Rexroth B.RUN. BLOCK NRFG KWD-030-FLS-C1-H-0 (R200271314) is a high-precision ball runner block designed for linear motion applications. This model is part of the NRFG series, which features a runner block body and all steel components made of corrosion-resistant steel in accordance with DIN standards. It is particularly suitable for use in environments such as the packaging industry and food industry subsectors, where hygiene and resistance to corrosive elements are crucial. The B.RUN. BLOCK NRFG KWD-030-FLS-C1-H-0 has a flange format (FLS) with standard width and height dimensions, offering a low preload (preload class C) and high accuracy (accuracy class H). Notably, this model does not include a ball chain, initial lubrication, preservation, or attachment elements on either the left or right front reference edge. The straight lube connection is loosely attached allowing for easy maintenance. With an overall length of the runner block being . mm, this product ensures interchangeability with guide rails across all accuracy classes. It boasts excellent dynamic characteristics with high load ratings in all four main directions of loading. Long-term lubrication capabilities are enhanced by lube fittings with metal threads on all sides. This ball runner block also features improved rigidity under liftoff and side loading conditions due to additional mounting screw holes at its center. The preloaded O-arrangement provides maximum system rigidity while its integrated all-around sealing protects against contamination. The optimized entry-zone geometry coupled with a high number of balls reduces variation in elastic deflection ensuring smooth operation. Attachments can be mounted from both above and below the ball runner block which offers versatility in installation. With its robust design and material specifications, it supports applications that require only one runner block per rail while maintaining high rigidity in every load direction.
