High-Precision Crown Wheel & Pinion Gears (Spiral Bevel Sets)

Performance & Racing Differentials

Under severe transportation missions and high-load off-road operating conditions, the drivetrain system endures immense torque pressure. The heavy-duty axle gears we manufacture for you are not just replacements—they are industrial-grade, optimized core drivetrain components. Forged from high-purity alloy steel, every gear set features a precision-engineered tooth geometry optimization design. This ensures that power transmission remains smooth and reliable even under extreme torque, effectively preventing premature wear and tooth breakage.

We offer free technical evaluations and RFQ consultations. Please send your gear specification drawings via email or WhatsApp, and our engineering team will provide a comprehensive quote and technical support within 24 hours.

Key Technical Metrics

Our Engineering & Manufacturing Advantages

Premium Material Selection

Utilizes high-quality alloy steel (such as 20CrMnTi), achieving a perfect balance between tensile strength and toughness.

High-Load Tooth Geometry Design

Optimizes contact pattern design to ensure even distribution of torque loads and prevent localized tooth breakage.

Heat Treatment Process

Adopts automatically controlled closed-loop carburizing and quenching to guarantee superior surface hardness (HRC 58-62) while preserving core toughness.

Micron-Level Inspection

Every product set passes Coordinate Measuring Machine (CMM) testing to fully satisfy DIN/ISO industry accuracy standards.

Fatigue Resistance Performance

Finished with precision polishing to achieve a lower friction coefficient, reducing metal stress fatigue under high temperatures.

Fitting Flexibility

Supports OEM replacements for mainstream vehicle models, while offering custom gear ratio solutions tailored to specific operating conditions.
