Product Description

High Torque External Gear Ratio 28:1 Planetary Gear Boxes

Planetary gearbox is a kind of reducer with wide versatility. The inner gear adopts low carbon alloy steel carburizing quenching and grinding or nitriding process. Planetary gearbox has the characteristics of small structure size, large output torque, high speed ratio, high efficiency, safe and reliable performance, etc. The inner gear of the planetary gearbox can be divided into spur gear and helical gear. Customers can choose the right precision reducer according to the needs of the application.
