The Bosch Rexroth B.RUNN. BLOCK NRII KWD-030-FNS-C2-H-0 (R200172304) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and accuracy. This model features the Resist NRII construction, which makes it suitable for environments with water-based media, acidic materials, alkali or saline solutions, as well as high humidity and temperatures. The runner block body and all steel components are made of corrosion-resistant steel according to DIN EN standards, ensuring durability and reliability in challenging conditions. With a size 30 designation and an FNS format (width flange, normal length, standard height), this ball runner block is part of Bosch Rexroth's Ball Rail Systems. It offers medium preload (class C) and high accuracy (class H), without a ball chain or initial lubrication. The product also lacks preservation treatments or attachment elements, providing a straightforward design for various applications. This model boasts an optimized entry zone geometry that significantly improves travel accuracy by up to six times compared to standard designs. It can be used with all SNS ball guide rails and is available in five common sizes. For lubrication, it features metal-threaded lube fittings on all sides and supports minimum quantity lubrication systems with integrated oil reservoirs. The dynamic characteristics of this ball runner block are exceptional due to its design that allows point contact in all loading directions, reducing friction to a minimum. A patented entry zone increases travel accuracy while minimizing variation in elastic deflection. The product can handle high load ratings in all four main directions of loading. The Bosch Rexroth B.RUNN. BLOCK NRII KWD-030-FNS-C2-H-0 is ideal for applications where rigidity and precision are paramount. Its long-term lubrication capabilities ensure several years of maintenance-free operation, making it an excellent choice for clean room environments or printed circuit board manufacturing where contamination must be avoided.
