The Bosch Rexroth B.RUN. BLOCK NRFG KWD-035-SLS-C0-H-0 (R201239314) is a high-precision ball runner block designed with advanced features to ensure optimal performance in various applications, particularly in the packing industry and food industry subsectors. This model boasts a slimline width, long length, and standard height format (SLS), providing a compact yet efficient design. The runner block body and all steel components are constructed from corrosion-resistant steel in accordance with DIN standards, ensuring durability and longevity even in harsh environments. With a preload class of C, this ball runner block operates preload-free, which is suitable for applications requiring smooth movement without additional friction. It falls under accuracy class H for high precision, guaranteeing accurate guidance and positioning. The overall length of the runner block is meticulously designed to accommodate specific industrial requirements. This product also features an end-face fastening thread for attachments and exhibits high rigidity in all load directions, allowing for the use of just one runner block per rail if necessary. The integrated all-around sealing system protects internal components from contaminants, while the optimized entry-zone geometry paired with a high number of balls reduces variation in elastic deflection during operation. Notably, this model does not include a ball chain or initial lubrication and lacks preservation measures. However, it is engineered for long-term lubrication over several years with lube fittings that have metal threads on all sides. Its interchangeability feature means it can be combined with any guide rails within each accuracy class without restrictions. The B.RUN. BLOCK NRFG KWD-035-SLS-C0-H-0 offers excellent dynamic characteristics thanks to its well-designed ball return system and guideway that ensures smooth and quiet running. Attachments can be conveniently mounted from above onto the ball runner block, enhancing ease of use and maintenance. In summary, this Bosch Rexroth ball runner block stands out for its corrosion resistance, high precision, dynamic load capacity, torsional moment load capacity, and ease of maintenance—making it an ideal choice for sophisticated linear movement applications where precision and reliability are paramount.
