The Bosch Rexroth MINI R.BLOCK NRII (R044479400) is a high-precision miniature ball runner block designed for seamless motion and load-bearing in compact applications. This model features a slimline width, long length, and standard height (SLS format), making it suitable for situations where space is at a premium. The runner block body is crafted from corrosion-resistant steel, ensuring durability and longevity even in challenging environments. With a preload class C, the MINI R.BLOCK NRII operates preload-free, which means it can accommodate applications requiring smooth movement without pre-tension. It falls within accuracy class N, indicating standard precision suitable for a wide range of uses. Notably, this model does not include a ball chain but comes with initial lubrication while foregoing preservation measures. The MINI R.BLOCK NRII boasts relubrication openings that facilitate maintenance and ensure consistent performance over time. The overall length of the runner block is optimized for its size category, and it's designed to be interchangeable with guide rails across all accuracy classes (P, H, and N), enhancing flexibility in use. The runner block operates quietly thanks to its well-designed ball return and guideway system. Additionally, ball retention features simplify replacement processes. This model can withstand dynamic load capacities as calculated according to DIN standards and can operate within an ambient temperature range from -10°C to +100°C. For applications requiring precise linear motion with minimal space usage, the Bosch Rexroth MINI R.BLOCK NRII offers reliability and adaptability. Its high-quality materials and engineering make it an ideal choice for various miniature profiled rail systems where corrosion resistance and maintenance ease are priorities.
