Slewing High Torque Planetary Gearbox

SGR N series planetary gearboxes are widely used in industrial and heavy duty applications. The planetary gearbox features compact size, low noise, excellent reliability and long service life. Linear or rectangular shaft configurations are available with male and female threads. The SGR outer shaft option (splined or cylindrical) can withstand high radial or axial loads on the output shaft. As a leading planetary gearbox manufacturer in China, planetary gearboxes are manufactured in a modular design, integrated according to customer requirements. Regarding the key components, SGR used qualified spare parts such as nodular cast iron body material, which can improve the rigidity and anti-knock performance of the gearbox. The low-speed shaft is equipped with a heavy-duty bearing that can withstand large radial loads due to proportional torque distribution. Each gear is hardened to ensure high reliability and long service life. SGR planetary gearbox has 16 models for different torque range, each model has 1-5 stages to achieve different gear ratios, in addition, SGR planetary gearbox has a wide range of high-speed designs: spur with key, hydraulic motor, electric motor. Multi-position installation, various types of fastening.
