| High Light | 20CrMnTi Alloy Steel Spiral Bevel Gear Set ，ISO 4-6 Grade Accuracy Bevel Gear Set ，Heavy-Duty Transmission Right-Angle Gear Set | ||
Our high-precision 20CrMnTi spiral bevel gear set is engineered for efficient and stable right-angle power transmission. Designed for heavy-duty industrial applications, this gear set delivers high torque capacity, smooth meshing performance, and long service life under demanding working conditions.
Manufactured with advanced CNC gear cutting and precision grinding technology, the gear set ensures excellent tooth contact pattern, low noise operation, and superior transmission efficiency.
20CrMnTi is a widely used low-carbon alloy carburizing steel known for:
Excellent hardenability
High core toughness
Superior surface wear resistance after carburizing
Stable dimensional performance after heat treatment
After carburizing and quenching, the surface hardness can reach HRC 58–62, significantly enhancing wear resistance and fatigue strength while maintaining a tough core structure.
✔ High load-bearing capacity
✔ Optimized spiral tooth geometry for smooth engagement
✔ Low vibration and reduced noise
✔ Precision ground tooth surface (DIN 6–8 available)
✔ Excellent pitting and bending fatigue resistance
✔ Customizable gear ratio and module
To ensure consistent quality and accuracy, our spiral bevel gear sets are produced through strict process control:
Material inspection (chemical & mechanical verification)
CNC gear cutting (Gleason / Klingelnberg compatible profiles)
Carburizing heat treatment
Gear tooth grinding
Tooth contact pattern inspection
Final dimensional and runout inspection
Each gear set undergoes comprehensive quality checks to guarantee performance reliability in high-load transmission systems.
This heavy-duty spiral bevel gear set is widely used in:
Industrial reducers and gearboxes
CNC power tool turrets
Robotics transmission systems
Agricultural machinery
Construction equipment
Packaging and automation equipment
