The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SNS-C0-N-0 (R201189404) is a high-precision ball runner block designed for linear motion applications. This product is part of the Ball Rail Systems and features a Resist NRII construction, which is corrosion-resistant and suitable for a variety of challenging environments. The runner block has a slimline width (SNS format), standard length, and height, ensuring compatibility with restricted spaces in transverse directions. The B.RUNN. BLOCK NRII is made with all steel components conforming to DIN EN standards, ensuring durability and resistance to corrosive substances. It comes preload-free (preload class C) with standard accuracy (accuracy class N) and does not include a ball chain or initial lubrication, allowing for customization based on application requirements. This model boasts an overall length of 52.4 mm and can be used interchangeably with guide rails of every accuracy level. Its design facilitates long-term lubrication over several years, which can significantly reduce maintenance frequency. Additionally, the patented entry zone enhances travel accuracy by up to six times compared to standard systems. The Bosch Rexroth ball runner block offers excellent dynamic characteristics due to its optimized entry-zone geometry and high ball count that minimize variation in elastic deflection. It also comes equipped with an integrated all-around sealing system for additional protection against contaminants. With a static load rating C0 of 8600 N and dynamic load capacity C of 12900 N, this product ensures reliable performance under various loading conditions. The maximum permissible linear speed is 5 m/s, while the permissible ambient temperature ranges from -30°C to +100°C for short periods. Overall, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SNS-C0-N-0 offers robust performance for linear motion systems requiring corrosion resistance, precision, and durability in challenging industrial environments.
