The Bosch Rexroth B.RUNN. BLOCK NRII KWD-035-FNS-C0-H-0 (R200139304) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications requiring high rigidity and accuracy. This runner block is part of Bosch Rexroth's Ball Rail Systems and is crafted from Resist NRII material, ensuring durability in harsh environments, including those with water-based media or high humidity levels. It features size 35 dimensions with an FNS format (width - flange, length - normal, height - standard), offering a compact and robust solution for various linear motion needs. The runner block comes without a ball chain, initial lubrication, or preservation, allowing for customization based on application requirements. It boasts an accuracy class H for high precision and is preload-free with preload class C. The steel components conform to DIN EN standards for corrosion resistance. Additionally, the product has an overall length of 90 mm and can be used interchangeably with guide rails of every accuracy level. Notable capabilities include long-term lubrication potential over several years, patented entry zone technology that significantly improves travel accuracy by up to six times, and compatibility with all SNS ball guide rails. The runner block supports dynamic load capacities and moments as per DIN ISO standards and has excellent dynamic characteristics suitable for varying operational demands. This Bosch Rexroth ball runner block is ideal for applications that demand maximum precision and longevity under conditions where exposure to corrosive elements is likely. Its design ensures minimal variation in elastic deflection due to its optimized entry-zone geometry and the high number of balls used in its construction. The product also features lube fittings with metal threads on all sides for easy maintenance and lubrication management.
