The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-FNS-C2-H-0 (R200122304) is a high-precision ball runner block designed for linear motion applications requiring rigidity, accuracy, and corrosion resistance. This model is part of the Ball Rail Systems product group, specifically crafted from Resist NRII material, which is a corrosion-resistant steel compliant with DIN EN standards. The ball runner block boasts a size 25 profile and an FNS format, indicating a flange width, normal length, and standard height. It comes with a medium preload (Preload class C) and high accuracy (Accuracy class H), ensuring reliable performance in precise applications. The runner block body has an overall length of 100 mm and does not include a ball chain or initial lubrication, allowing for customization based on specific application requirements. It operates efficiently within an ambient temperature range of -10°C to 100°C and can withstand dynamic load capacities as per DIN ISO standards. This model is interchangeable with guide rails to facilitate versatile use across various industries. It features lube fittings with metal threads on all sides for easy maintenance and long-term lubrication options spanning several years. The patented entry zone enhances travel accuracy significantly—up to six times—while the optimized geometry and high number of balls reduce variation in elastic deflection. Designed without seals as standard but compatible with various seal types such as SS (Standard Seal), LS (Low-friction Seal), DS (Double-lip Seal), front seals, FKM seals, and cover plate wipers available for separate purchase, this runner block can adapt to different environmental conditions while preventing contaminants from affecting its service life. Overall, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-FNS-C2-H-0 is engineered for applications requiring maximum precision and durability in challenging environments where corrosion resistance and long-term reliability are paramount.
