Wtth the world’s best gear design and analysis technologies, SDG has been researching the optimized gear solutions for more than ten years in the USA. Including heavy industries, air crafts, automobiles, and even ultra-high precision fields, SDG has been helping solving gear problems and improving the performance. As a new name, SDG, we are equipped with state-of-the-art machineries, assembly lines, and the best crews, we stepped forward to become a “gear company with total services”.
