The Bosch Rexroth B.RUN. BLOCK NRFG KWD-020-FLS-C0-H-0 (R200289314) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and high accuracy. This particular model is tailored for the packaging industry as well as various subsectors of the food industry, where hygiene and material integrity are of utmost importance. The runner block features a flange format (FLS) with a width, length, and height that adhere to standard dimensions. The body and all steel components are constructed from corrosion-resistant steel in accordance with DIN standards. It is classified under preload class C, indicating that it is preload-free, and falls within accuracy class H for high precision. This model does not include a ball chain, preservation treatment, or initial lubrication and lacks attachment elements on both the left front reference edge and right front reference edge. The straight lube connection comes loosely attached. Its overall length measures precisely . mm. Interchangeable with guide rails of every accuracy level, this runner block maintains high load ratings in all four primary directions of loading. Long-term lubrication capabilities extend over several years due to strategically placed lube fittings with metal threads on all sides. Additional mounting screw holes at the center enhance rigidity under liftoff and side loading conditions. The preloaded O-arrangement contributes to maximum system rigidity while allowing for end-face fastening thread attachments. The integrated all-around sealing coupled with an optimized entry-zone geometry ensures minimal variation in elastic deflection during operation. Smooth and quiet running is achieved through a well-designed ball return system. Furthermore, attachments can be mounted from both above and below the block, providing flexibility in application design. Dynamic load capacities and load moments are calculated based on a 100 km travel as per DIN ISO standards, ensuring reliable performance over extended periods of use.
