The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-FNS-C2-H-0 (R200182304) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and precision. This product is part of the Ball Rail Systems and is crafted from Resist NRII, a corrosion-resistant steel compliant with DIN EN standards, ensuring durability and longevity even in harsh environments. The runner block boasts a size 20 profile with an FNS format, indicating a flanged width, normal length, and standard height. With an accuracy class of H for high precision and a preload class C indicating medium preload, this runner block delivers exceptional performance without the inclusion of a ball chain. It lacks initial lubrication and preservation, allowing users to apply their choice of lubricants according to specific application needs. The product also features a straight lube connection that is loosely attached for ease of maintenance. The dynamic characteristics of the B.RUNN. BLOCK NRII are outstanding due to its optimized entry-zone geometry and the use of numerous balls which reduce the variation in elastic deflection significantly. This design innovation contributes to increased travel accuracy by up to six times compared to conventional systems. Additionally, it supports long-term lubrication spanning several years. This Bosch Rexroth ball runner block has been engineered for applications demanding high rigidity and maximum precision. Its interchangeable design permits compatibility with all SNS Ball Guide Rails across various sizes, enhancing its versatility in different setups. Moreover, the product's dynamic load capacity C and torsional moment load capacities are determined following DIN ISO standards based on a 100 km travel criterion. The ball runner block's dimensions include an overall length of . mm and it can operate within ambient temperatures ranging from min ... max °C for short periods. In summary, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-FNS-C2-H-0 (R200182304) represents an advanced solution for linear motion systems that demand high precision, corrosion resistance, and dynamic performance across various industrial applications.
