Ningbo Planetary Gearbox Factory (NBPG) was founded in 1988 as a professional planetary gearbox manufacturer. Our NB3 series planetary gearbox, NB4 series traveling gearbox, NB7 series slewing drive, NB6 series wheel drive planetary gearbox has developed into 10,000 kinds of specifications, with gear ratio range of 3.3 ~ 9000 and output torque range of 500 ~ 450000N.m. More than 90% of our gear units are exported to the USA, Europe, Australia, South America, the Middle East and Southeast Asia. As a manufacturer with 25 years of production experience, we provide planetary gearboxes that have the entirely consistent dimensions with those made by famous manufacturers in Europe and the US so as to enable interchangeable use, including:
