The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-FNS-C1-P-0 (R200181204) is a high-precision ball runner block designed for use in linear motion applications requiring corrosion resistance and precision movement. This runner block is constructed with Resist NRII, a material known for its corrosion-resistant properties, making it ideal for environments with water-based media, acidic materials, alkali or saline solutions, and high humidity levels above 100%, including clean rooms and PCB manufacturing. It features a size 20 profile with an FNS format, indicating a flange width, normal length, and standard height. The runner block body and all steel components are made of corrosion-resistant steel as per DIN EN standards. The low preload class C ensures smooth motion with low resistance, while the precision accuracy class P guarantees exact movements required for applications that demand high rigidity and long-term lubrication over several years. This model does not include a ball chain or initial lubrication and comes without attachment elements on the left or right front reference edges. It has a straight lube connection loosely attached for ease of maintenance. The overall length of the runner block is meticulously crafted to ensure interchangeability with guide rails of every accuracy level. The Bosch Rexroth ball runner block boasts excellent dynamic characteristics due to its optimized entry-zone geometry and high number of balls which minimize variation in elastic deflection. It is suitable for all SNS ball guide rails and comes in five common sizes. The product also features lube fittings with metal threads on all sides for easy maintenance, ensuring consistent performance even under varying load directions. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-FNS-C1-P-0 (R200181204) offers exceptional durability and precision for demanding linear motion applications within industries that face exposure to corrosive environments or require clean room compatibility.
