Whether you're building a new planetary system or replacing worn parts, this internal gear delivers the performance and durability professionals count on.
The Type 18 internal gear is a critical part of the planetary gearbox assembly, working in perfect sync with sun gears and planet gears to transmit high torque with minimal backlash. Manufactured from forged alloy steel and processed through carburizing, quenching, and precision grinding, this gear is ideal for ZL series loaders and other mainstream brands.
Pop this into your gearbox, and you’ll notice smoother rotation and way less vibration—trust us.
Material Strength: High-strength alloy steel with deep carburizing and quenching, hardness up to HRC 58–62.
Precision Fit: Machined using advanced CNC and gear hobbing systems to ensure perfect internal meshing.
High Load Capacity: Designed to handle repeated stress under full load conditions.
Reliable Quality Control: Every gear goes through crack inspection, quench depth testing, and metallographic analysis.
Let’s be real, this gear don’t just fit, it performs like a champ.
This 18-type internal gear is widely used in the planetary reduction systems of wheel loaders, especially those operating in construction, mining, and agricultural sectors. It supports OEM assembly, aftermarket repair, and custom gearbox development for brands across Asia, the Middle East, and South America.
With over 39 years of production experience, 310+ skilled employees, and 500+ gear machining units, we offer a vertically integrated manufacturing system that ensures tight quality control, quick delivery, and cost-effective customization.
We’re not just a gear factory—we’re your long-term solution partner in heavy equipment transmission systems.
