The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-SNS-C0-N-0 (R201129406) is a ball runner block designed for precision and corrosion resistance in challenging environments. This runner block is made from Resist NRII, a corrosion-resistant material that ensures durability and consistent performance. It features a slimline width, normal length, and standard height (SNS format), making it suitable for applications with limited space in the transverse direction. The runner block body and all steel components are crafted from corrosion-resistant steel as per DIN standards. With a preload class C0, this model is preload-free, ensuring smooth motion without initial tension in the system. It also falls under accuracy class N, signifying standard precision levels. The inclusion of a ball chain contributes to reduced noise levels and improved travel behavior, enhancing the overall user experience. This model is designed without preservation or initial lubrication and does not include attachment elements on either front reference edge. However, it does come with a straight lube connection loosely attached for easy maintenance. The runner block boasts an overall length of 52 mm and offers the flexibility to combine with guide rails of varying accuracies. The B.RUNN. BLOCK NRII KWD-025-SNS-C0-N-0 is capable of long-term lubrication over several years and features significantly reduced frictional oscillations with low friction force levels, especially under external load conditions. Its patented entry zone increases travel accuracy by up to six times compared to standard models. Additional characteristics include a dynamic load capacity C determined by DIN ISO standards for 100 km travel distance (with values adjustable based on actual stipulation), compatibility with five common sizes of SNS ball guide rails, and metal thread lube fittings on all sides for convenient access. Attachments can be mounted from above the runner block, which supports high load ratings in all four main loading directions. Integrated all-around sealing provides protection against contaminants while maintaining excellent dynamic characteristics essential for various applications. The Bosch Rexroth ball runner block ensures minimal variation in elastic deflection due to its optimized entry zone geometry and high number of balls, leading to superior performance in linear motion systems.
