20CrMnTi Alloy Steel Spiral Bevel Gear with ISO 5-6 Grade Accuracy and HRC 55-62 Hardness for Right-Angle Transmission

20CrMnTi Spiral Bevel Gear | Integral Carburized High-Precision Right-Angle Transmission Component

The 20CrMnTi Spiral Bevel Gear shown above features a compact, precision-machined structure with optimized spiral tooth geometry. The gear teeth exhibit a smooth, uniform helix profile and high surface finish, reflecting advanced machining and grinding processes. The integrated hub design enhances structural rigidity while ensuring stable mounting and torque transmission.

Designed for right-angle power transmission systems, this spiral bevel gear delivers smooth engagement, reduced vibration, and reliable performance in industrial applications requiring durability and precision.

Key Material – 20CrMnTi Alloy Steel

20CrMnTi is a premium carburizing alloy steel widely used in high-performance transmission components due to its excellent balance of hardness and toughness.

Material Advantages:

• Excellent carburizing capability

• High surface hardness after heat treatment

• Strong core toughness

• Outstanding wear and fatigue resistance

• Stable dimensional control after quenching

After integral carburizing and quenching treatment, the gear surface hardness reaches HRC 55–62, significantly improving resistance to pitting, scuffing, and tooth wear while maintaining a tough internal structure.

Performance Advantages

Compared with conventional bevel gears, this spiral bevel gear offers:

• Higher contact ratio

• Improved load distribution

• Reduced mechanical shock

• Enhanced transmission efficiency

• Longer operational lifespan

Its compact structure and precision bore design make it especially suitable for industrial gearboxes and right-angle drive assemblies.
