Planetary gear system is usually a type of epicyclic gear system used in exact and high-efficiency transmissions. Planetary gearing, using its inherent in-series shafting and cylindrical casing, is usually often named the compact option to standard pinion-and-equipment reducers. Being suited for a wide range of applications – from electric screwdrivers to bulldozer power trains – these systems are solid contenders when space and 
weight versus reduction and torque are chief issues.
We have vast experience in production planetary gearbox and gear components such as sun gear, world carrier, and ring gear in China.
We employ the most advanced devices and technology in manufacturing our gear models. Our inspection procedures comprise study of the torque and components for plastic, sintered metallic, and steel planetary gears. We offer various assembly styles for your gear reduction projects.
