The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-FNS-C1-N-0 (R20018140) is a high-precision ball runner block designed for linear motion applications that demand both corrosion resistance and precision. This runner block is part of the Bosch Rexroth ball rail system and is made from Resist NRII, a corrosion-resistant steel that conforms to DIN EN standards, ensuring durability and longevity in challenging environments. This model features a size 20 runner block with an FNS format, which includes a width flange, normal length, and standard height. It has a low preload class C and standard accuracy class N. The product does not include a ball chain, preservation, or initial lubrication. Furthermore, it lacks attachment elements on the left and right front reference edges. The runner block body comes in the standard version with an overall length of 63 mm. It boasts interchangeability attributes, allowing it to combine with guide rails of every accuracy level seamlessly. The patented entry zone of this runner block enhances travel accuracy up to six times compared to conventional systems. Designed for high rigidity requirements, this product supports long-term lubrication over several years while maintaining maximum precision. The dynamic characteristics are excellent due to optimized entry zone geometry and a high number of balls which minimize variation in elastic deflection. The dynamic load capacity (C) follows DIN ISO standards based on 100 km travel; however, the values can be adjusted for comparison if only 50 km travel is stipulated by multiplying by 1.26. The permissible ambient temperature range for this product spans from -30°C up to +100°C for short periods. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-FNS-C1-N-0 is an adaptable and robust component suitable for various linear motion applications where corrosion resistance and precision are paramount. Its design allows for easy integration into existing systems while providing reliable performance under varying environmental conditions.
