The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-FNS-C0-N-0 (R200189404) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and precision. This model, made from Resist NRII material, offers robust performance with all its steel components conforming to DIN EN standards for corrosion-resistant steel. It features a size 20 profile with an FNS format, which denotes a flange width, normal length, and standard height. The runner block operates preload-free (preloading class C) and adheres to the standard accuracy class N. It does not include a ball chain, initial lubrication, preservation, or attachment elements on the left or right front reference edges. The runner block body comes in a standard version with an overall length of 63 mm. This particular model is characterized by its ability to offer high rigidity for demanding applications and supports long-term lubrication over several years for maximum operational efficiency. It boasts patented entry zone technology that significantly enhances travel accuracy by up to six times compared to traditional systems. Designed for interchangeability, this ball runner block can be used with all SNS ball guide rails and is available in five common sizes. The dynamic characteristics of this component are exceptional due to its optimized entry-zone geometry and the high number of balls which minimize variation in elastic deflection. Additional features include lube fittings with metal threads on all sides, high load ratings in all four main loading directions, and a minimum quantity lubrication system integrated into the design. The product operates within a permissible ambient temperature range of -10°C to +100°C for short periods. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-FNS-C0-N-0 (R200189404) is an advanced ball runner block designed for applications where corrosion resistance and precision are paramount. Its construction ensures long-lasting durability and consistent performance in various industrial environments.
