As a professional manufacturer with over 10,000-30,000 square meters of factory space and years of experience in precision gear manufacturing, Henan San Kuang Machinery Technology Co., Ltd. proudly presents our high-quality 20CrMnTi Ring Gear (both internal and external configurations). This gear is engineered to deliver exceptional durability, precision, and performance in demanding power transmission applications. With a hardness range of HRC 58-62 and precision rating of AGMA Q10, our ring gear ensures reliable operation and long service life even under heavy loads and high speeds.
The 20CrMnTi alloy steel provides excellent core toughness and wear resistance after carburizing and quenching heat treatment. Our advanced manufacturing processes and strict quality control guarantee consistent tooth geometry, minimal runout, and smooth meshing. Whether you need internal ring gears for planetary gear systems or external ring gears for large drives, we offer customizable solutions to meet your specific requirements. Our products are widely exported to North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania and many other regions, trusted by clients in heavy machinery, automotive, mining, and industrial equipment sectors.

Product Advantages & Benefits
Superior Wear Resistance: The HRC 58-62 hardness combined with carburized case provides excellent resistance to abrasive wear and pitting, extending gear life significantly.
High Load Capacity: 20CrMnTi alloy offers high core strength, enabling the gear to transmit large torques without deformation.
Precise AGMA Q10 Accuracy: Our gears are manufactured on advanced CNC gear hobbing and shaping machines, ensuring tooth profile, lead, and pitch errors within tight tolerances. This results in smooth, quiet operation and reduced vibration.
Versatile Dual Configuration: Available in both internal and external gear designs, suitable for planetary gear sets, ring drives, and various transmission systems. The same high quality applies to both types.
Customizable Geometry: We can tailor tooth modifications (tip relief, crowning) to optimize contact pattern and noise performance according to your application.
Rigorous Quality Control: Every gear undergoes hardness testing (Rockwell), gear measuring center inspection, magnetic particle flaw detection, and dimensional verification to ensure consistency.
Typical Applications
Planetary gearboxes in construction machinery (excavators, bulldozers)
Wind turbine yaw and pitch drives
Heavy-duty truck and mining vehicle transmissions
Industrial gear reducers for steel mills and cement plants
Marine propulsion systems and offshore equipment

Frequently Asked Questions (FAQ)
Q1: What is the typical lead time for custom ring gears?
A: Lead time depends on complexity and quantity. Typically, it ranges from 30 to 60 days for standard customization. We can expedite for urgent orders upon request.Q2: Can you provide gears with different hardness requirements?
A: Yes, the hardness HRC 58-62 is our standard for 20CrMnTi, but we can adjust the heat treatment process to meet other hardness ranges if required, subject to technical feasibility.Q3: Do you offer samples before mass production?
A: Yes, sample orders are welcome. We can produce a prototype or first article for your evaluation. Sample cost and shipping terms can be discussed.Q4: What is the minimum order quantity (MOQ)?
A: For standard ring gears, MOQ is usually 10 pieces. For custom designs, MOQ may vary; please contact us for details.Q5: How do you ensure gear quality meets AGMA Q10?
A: We use CNC gear measuring machines (MM/MR) to inspect tooth parameters. Each gear is tested for hardness, runout, and tooth contact. Our quality system follows ISO9001 procedures.Q6: Can you supply both internal and external ring gears in one order?
A: Absolutely. We can manufacture matched sets of internal and external gears to ensure proper meshing and backlash control.Q7: Do you provide technical drawing support for custom designs?
A: Yes, our engineering team can assist in gear design and provide 2D/3D drawings. We recommend customers provide their specifications for optimal design.Q8: What packing and shipping options are available?
A: Gears are packed in wooden crates with anti-rust oil and foam protection. We ship via sea, air, or express as per your request, from Shanghai, Qingdao, Tianjin, or Lianyungang ports.
