The Bosch Rexroth B.RUNN. BLOCK NRII KWD-015-FNS-C1-H-0 (R200111304) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and precision. This model is part of Bosch Rexroth's Ball Rail Systems, constructed from Resist NRII material, which makes it suitable for environments with water-based media, diluted acids, alkalis, saline solutions, and high humidity levels above 70% as well as temperatures exceeding 100°C. With its FNS format (flange width, normal length, standard height), the runner block body and all steel components are made of corrosion-resistant steel per DIN EN standards. It features a low preload class C and a high accuracy class H but comes without a ball chain or initial lubrication. The product has no attachment elements on either front reference edge and includes a straight lube connection loosely attached. Designed to meet rigorous rigidity requirements, this runner block can facilitate long-term lubrication over several years while maintaining maximum precision. Its patented entry zone increases travel accuracy up to six times and it can be used with all SNS ball guide rails. Available in five common sizes, the runner block ensures high load ratings in all four main directions of loading due to its excellent dynamic characteristics. The model also includes an integrated minimum quantity lubrication system with an oil reservoir for optimized performance. The optimized entry-zone geometry along with a high number of balls reduces variation in elastic deflection. The overall length of the runner block is specified as . mm, while the height is . mm when combined with the guide rail. For specific environmental conditions such as temperature ranges from min ... max °C (admissible for short periods), users are advised to consult Bosch Rexroth for guidance. The dynamic load capacity C and dynamic torsional moment load capacity Mt are determined based on a 100 km travel per DIN ISO standards; however, users can multiply these values by 1.26 for comparison when only 50 km travel is stipulated. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-015-FNS-C1-H-0 offers exceptional durability and precision for demanding linear motion applications where corrosion resistance and long-term reliability are critical factors.
