The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-FNS-C0-H-0 (R200129304) is a high-precision ball runner block designed for linear motion systems requiring corrosion resistance and accuracy. This model is part of the Ball Rail Systems product line and features a Resist NRII construction, which is made of corrosion-resistant steel compliant with DIN EN standards, making it suitable for environments with high humidity or exposure to corrosive media such as water-based solutions, acidic materials, alkalis, or saline solutions. The runner block has a format FNS, indicating a flanged width, normal length, and standard height. It boasts an accuracy class H for high precision and is preload-free (preload class C), ensuring smooth motion without unnecessary tension in the system. The product does not include a ball chain, initial lubrication, preservation, or attachment elements on the left or right front reference edges. With an overall length of 70 mm and the ability to combine with any guide rails within its accuracy class interchangeably, this runner block meets diverse application requirements. It is engineered to provide long-term lubrication over several years while maintaining maximum precision. The patented entry zone increases travel accuracy up to six times compared to conventional designs. The B.RUNN. BLOCK NRII KWD-025-FNS-C0-H-0 can handle high rigidity demands and offers excellent dynamic characteristics due to the optimized entry-zone geometry and a high number of balls that minimize variation in elastic deflection. It supports minimum quantity lubrication systems with integrated reservoirs for oil lubrication and provides high load ratings in all four main loading directions. This product is suitable for clean room applications as well as general printed circuit board manufacturing due to its clean construction without additional corrosion protection needed. It's also ideal for packaging industry applications where precise linear movement is crucial.
