ZM INDUSTRY CO., LTD
ZM INDUSTRY CO., LTD successfully completed the export of planetary carriers, girth gears, and pinion shafts to Durban, South Africa. The goods were shipped using 40OT open-top containers, specially selected for their ability to handle oversized, heavy industrial components securely and efficiently.
Products Description
Planetary Carrier
- The Core Link of Power Transmission
The planetary carrier (also known as carrier planetary or planet carrier gear) connects the sun gear and planet gears within a planetary gear set, ensuring stable torque transmission and balanced load distribution. It serves as the structural center of the planetary gear system, vital for high-precision machinery and heavy-duty planetary gear motors.


Girth Gear
- The Foundation of Industrial Rotation
The girth gear is the main driving gear used in mills, kilns, and rotary systems. It transfers rotational energy from the pinion shaft to the machine body, ensuring smooth, stable, and synchronized motion. Manufactured with CNC cutting and heat treatment, it offers excellent balance and long lifespan in continuous heavy-load operation.
Pinion Shaft
- The Precision Drive Source
The pinion shaft acts as the initial torque input for planetary gear and mill drive systems. Its high concentricity and hardened surface guarantee optimal gear engagement and energy efficiency. Together with the girth gear, it forms a reliable drive pair for continuous mechanical operation.
