The High-Hardness 20-Tooth Spiral Bevel Gear Set (Module 2) is engineered for precision right-angle transmission systems requiring superior wear resistance, high torque capacity, and stable long-term performance. Designed with optimized spiral tooth geometry and manufactured using high-quality carburizing alloy steel, this gear set ensures smooth power transfer and reduced operational noise in industrial gearbox applications.
With controlled heat treatment and precision grinding processes, the gear set achieves high surface hardness while maintaining a tough core structure—making it suitable for heavy-duty and continuous-load environments.
Premium 20CrMnTi Alloy Steel: This gear set is forged from 20CrMnTi, a specialized alloy known for its exceptional hardenability and impact toughness.
Advanced Carburizing & Quenching: Through rigorous heat treatment, the gears achieve a surface hardness of HRC 55-62, while the core remains resilient to absorb heavy shocks and prevent tooth breakage.
Spiral Tooth Geometry: The curved teeth engage gradually rather than all at once, which minimizes vibration and allows for smooth high-speed rotation.
Precision-Cut Spline Shaft: The pinion is integrated with an external spline shaft, allowing for direct and secure coupling with drive motors or transmission systems.
Lapped & Matched Pairs: Every set is factory-lapped as a pair to ensure a perfect tooth contact pattern, guaranteeing maximum mechanical efficiency and a long service life.
Heavy-Duty Power Tools: Professional-grade angle grinders and industrial cutters.
Automotive Differentials: Small to medium vehicle drivetrains and steering gearboxes.
Industrial Machinery: Right-angle speed reducers, conveyor drive units, and printing presses.
Agriculture & Forestry: Gearbox components for harvesters, tractors, and wood processing equipment.
