The Bosch Rexroth B.RUN. BLOCK NRFG KWD-020-FNS-C2-H-0 (R200182314) is a high-precision ball runner block designed for demanding linear motion applications. This product is part of the NRFG series, crafted from corrosion-resistant steel to ensure durability and longevity, even in challenging environments such as the packaging and food industry subsectors. The B.RUN. BLOCK features a size 20 runner block with a flange width, standard height, and normal length, conforming to DIN standards for steel components. With a preload class C indicating a medium preload level and an accuracy class H for high precision, this ball runner block is engineered to deliver reliable performance with excellent dynamic characteristics. It boasts high load ratings in all four main directions of loading and is compatible with all SNS ball guide rails, offering limitless interchangeability within each accuracy class. The B.RUN. BLOCK NRFG KWD-020-FNS-C2-H-0 is designed without a ball chain, preservation, or initial lubrication and does not include attachment elements on either the left or right front reference edges. The overall length of the runner block is precisely manufactured to ensure compatibility with corresponding guide rails. This model provides maximum system rigidity due to its preloaded O-arrangement and features an end-face fastening thread for various attachments. Its integrated all-around sealing coupled with optimized entry-zone geometry ensures minimized variation in elastic deflection during operation. Additionally, it delivers smooth and quiet running thanks to its well-designed ball return and guideway system. The product also includes enhanced rigidity under lift-off and side-loading conditions due to two extra mounting screw holes at the center of the runner block. Long-term lubrication capabilities are possible over several years with lube fittings that have metal threads on all sides. The Bosch Rexroth B.RUN. BLOCK NRFG KWD-020-FNS-C2-H-0 represents a robust solution for linear motion requirements where both precision and corrosion resistance are critical factors.
