The Bosch Rexroth B.RUNN. BLOCK NRII KWD-015-SNS-C0-H-0 (R201119304) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications demanding both accuracy and durability. This product is part of the Ball Rail Systems and features a slimline width, normal length, and standard height, conforming to the SNS format. It is constructed from Resist NRII material, ensuring resistance against corrosive agents such as water-based media, diluted acids, alkaline solutions, and saline environments. The runner block boasts a high accuracy class H and is preload-free with a preload class C. It does not include a ball chain or initial lubrication, allowing for customization based on the user's lubrication preferences. The body of the runner block and all steel components are made of corrosion-resistant steel according to DIN EN standards. With an overall length of 63 mm, this model ensures interchangeability with guide rails of varying accuracies. It is designed for long-term lubrication over several years and offers reduced frictional oscillations with a low friction force level under external loads. The patented entry zone improves travel accuracy significantly by up to six times. This model supports dynamic load capacity and load moments based on 100 km travel as per DIN ISO standards. It features lube fittings with metal threads on all sides for easy maintenance and an integrated minimum quantity lubrication system with an oil reservoir. The optimized entry zone geometry along with numerous balls reduces variation in elastic deflection while maintaining excellent dynamic characteristics. The B.RUNN. BLOCK NRII KWD-015-SNS-C0-H-0 includes an integrated all-around sealing system that protects against contaminants while maintaining low friction levels. Its design allows attachments to be mounted from above for ease of installation. Suitable for various industrial applications where space is restricted in the transverse direction, this Bosch Rexroth ball runner block ensures reliable performance even in extreme conditions without additional corrosion protection, making it suitable for clean rooms and general printed circuit board manufacturing among other uses.
