The Bosch Rexroth B.RUNN. BLOCK NRII KWD-015-FNS-C2-H-0 (R200112304) is a high-precision, corrosion-resistant ball runner block designed for demanding linear motion applications. This model features a size 15 runner block body made of Resist NRII material, which ensures durability and resistance to corrosive substances such as water-based media, acidic materials, alkali, or saline solutions. The FNS format indicates a flanged width with normal length and standard height. With an accuracy class of H for high precision and a medium preload class C, the runner block demonstrates excellent dynamic characteristics and rigidity, making it suitable for applications requiring maximum precision over long periods. It does not include a ball chain or initial lubrication and comes without preservation or attachment elements on the left front reference edge or the right front reference edge. This ball runner block is interchangeable with guide rails of every accuracy level, offering flexibility in system design. It supports a minimum quantity lubrication system with an integrated reservoir for oil lubrication and boasts an optimized entry zone geometry that enhances travel accuracy by reducing elastic deflection variation. The product is part of Bosch Rexroth's Ball Rail Systems designed to handle high load ratings in all four main loading directions while maintaining low friction due to its four rows of balls with point contact. Seals like the standard SS seal prevent contaminants from entering the block mechanism, preserving its service life even in harsh environments. Overall, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-015-FNS-C2-H-0 is ideal for use in environments with high humidity and temperature conditions such as clean rooms, circuit board manufacturing, cleaning plants, electroplating lines, vapor degreasing plants, refrigeration systems, and general packaging industry applications where corrosion resistance and precision are paramount.
