The Bosch Rexroth B.RUN. BLOCK NRFG KWD-025-FNS-C1-H-0 (R200121314) is a high-precision ball runner block designed for superior performance in various applications, particularly in the packaging and food industry subsectors. This runner block boasts an accuracy class H for high accuracy and a preload class C indicating low preload, enhancing its precision and reliability in operation. It is constructed with corrosion-resistant steel compliant with DIN standards, ensuring durability and longevity even in challenging environments. With a size N tolerance profiled rail system, this ball runner block facilitates smooth, quiet movement and optimized load distribution thanks to its optimized entry-zone geometry and a high number of balls which minimize variation in elastic deflection. The dynamic load capacity C and dynamic torsional moment load capacity Mt are determined based on a 100,000 m travel as per DIN ISO standards, providing users with reliable data for assessing performance suitability. This model does not include a ball chain or initial lubrication, allowing for customization based on specific application needs. Its design permits long-term lubrication over several years, reducing maintenance requirements. The lube fittings feature metal threads on all sides for secure attachment. The Bosch Rexroth B.RUN. BLOCK NRFG KWD-025-FNS-C1-H-0 is characterized by its limitless interchangeability within each accuracy class across all Ball Rail Systems and Ball Runner Block versions. It offers maximum system rigidity due to its pre-tensioned O-arrangement and has an end-face fastening thread for various attachments. Its integrated all-around sealing protects against contaminants, while the additional mounting screw holes at the center of the block improve rigidity under liftoff and side loading conditions. Overall, this product provides exceptional dynamic characteristics, high load ratings in all four main directions of loading, and can be used on all SNS ball guide rails. Its design allows attachments to be mounted from both above and below the runner block, offering versatility in integration into different systems.
