The Bosch Rexroth B.RUNN. BLOCK NRII KWD-030-FNS-C1-P-0 (R200171204) 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 and is characterized by its Resist NRII construction, making it suitable for use in harsh environments where exposure to water-based media, acidic materials, alkali, saline solutions, or high humidity may occur. The runner block body, along with all steel components, is made from corrosion-resistant steel compliant with DIN EN standards. The B.RUNN. BLOCK NRII KWD-030-FNS-C1-P-0 features an FNS size format which indicates a flanged width, normal length, and standard height. It has a low preload of class C and an accuracy class P for precision applications. Notably, this model does not include a ball chain or initial lubrication and comes without preservation or attachment elements. This runner block offers excellent dynamic characteristics due to the optimized entry-zone geometry and the high number of balls which minimize variation in elastic deflection. It is also equipped with lube fittings that have metal threads on all sides for long-term lubrication capabilities over several years. The product has been engineered to provide the same high load ratings in all four main directions of loading and can be used on all SNS Ball Guide Rails. Additionally, its patented entry zone increases travel accuracy up to six times compared to standard systems. With an overall length of 73 mm and a height of 24 mm when paired with a guide rail, the B.RUNN. BLOCK NRII KWD-030-FNS-C1-P-0 ensures maximum rigidity requirements are met while offering interchangeability across various accuracy classes of guide rails. In summary, this Bosch Rexroth ball runner block is well-suited for applications demanding maximum precision and durability against corrosive elements while maintaining excellent dynamic performance and load capacity across multiple orientations.
