Heavy Machinery
From excavators to offshore cranes, our gears withstand 500+ daily rotation cycles without wear.
High-Temperature Environments
Ceramic-coated raceways and specialized heat treatment ensure stability in steel mills (120℃+).
Precision-Dependent Systems
Micron-level accuracy and grease-free operation make our compact series ideal for surgical robots.
Corrosive Conditions
Marine-grade seals and slewing ring gear 2000+ hour salt-spray tested gears thrive in tidal energy systems.
1. Material Integrity: Sourced from ISO-certified mills, steel undergoes vacuum degassing for 99.99% purity.
2. Precision Manufacturing: CNC grinding + 12+ tests (fatigue, vibration, sealing) per batch.
3. Lifecycle Validation: Digital twin simulations replicate 10,000+ operational hours pre-production.

1. How do I choose a product for 500-ton excavators?
Our engineers analyze load distribution, RPM, and environmental factors to recommend materials (e.g., INNO-7XT alloy) and heat treatment.
2. Can you provide P4-level gears for medical equipment?
Yes. Our compact precision series achieves <5μm runout and grease-free operation for MRI machines.
3. What certifications ensure gear quality?
Every batch complies with ISO 9001, CE, and GB/T standards. AGMA/DNV GL certifications available upon request.
4. Do you offer corrosion-resistant coatings?
Yes. Electroless nickel plating or ceramic coatings for offshore/wastewater applications.
5. How fast can you replace a failed port crane gear?
With regional hubs in EU/NA/Asia, we guarantee 72-hour delivery for emergency replacements.
