The Bosch Rexroth B.RUNN. BLOCK NRII KWD-015-FNS-C1-N-0 (R200111404) is a ball runner block designed for precision linear movement and rigidity in various applications. This component is part of the Ball Rail Systems and is specifically crafted from Resist NRII, a corrosion-resistant material suitable for harsh environments. It features a size 15 flange width, normal length, and standard height. The runner block body and all steel components are made of corrosion-resistant steel according to DIN EN standards. This model offers a low preload with its C1 preload class, ensuring smooth movement with minimal friction. The accuracy class N indicates that it adheres to standard precision requirements. Notably, this runner block does not come with a ball chain, initial lubrication, preservation, or attachment elements on either front edge. The B.RUNN. BLOCK has an overall length of 63 mm and boasts an interchangeable design that allows compatibility with guide rails across all accuracy classes. It's engineered for high rigidity demands and supports long-term lubrication over several years while providing maximum precision. Additional features include patented entry zone technology that improves travel accuracy up to six times compared to standard systems, making it ideal for applications requiring exceptional dynamic characteristics. The runner block can be used on all SNS ball guide rails and comes in five common sizes with lube fittings equipped with metal threads on every side. It has excellent load ratings in all four main loading directions due to its design which includes four rows of balls providing point contact. The product also incorporates a minimum quantity lubrication system with an integrated reservoir for oil lubrication and optimized entry-zone geometry which reduces variation in elastic deflection. The Bosch Rexroth ball runner block is suitable for applications where high rigidity and precision are paramount, such as in clean rooms or general printed circuit board manufacturing due to its resistance against water-based media, acidic materials, alkali or saline solutions at relative humidities above 70% and temperatures exceeding 100°C.
