As a trusted manufacturer based in Luoyang, Henan, China, Henan San Kuang Machinery Technology Co., Ltd. specializes in high-quality power transmission components. Our Integral Ring Gear with Custom Teeth 20-120 is engineered for demanding industrial applications where reliability and longevity are paramount. Crafted from 20CrMnTi alloy steel and subjected to precision quenching treatment, this gear offers exceptional wear resistance, high load-bearing capacity, and consistent performance under extreme conditions. With over 10 years of manufacturing experience, a factory spanning 10,000–30,000 square meters, and a dedicated team of 51–100 employees, we deliver customized solutions that meet the exact needs of your project.
Our integral ring gear is manufactured as a one-piece construction, eliminating weak weld joints and ensuring superior strength and dimensional stability. The 20CrMnTi material is widely recognized in the gear industry for its excellent hardenability, high toughness, and resistance to fatigue, making it ideal for heavy-duty applications such as mining equipment, construction machinery, cement mills, and wind turbines. The quenching process further enhances surface hardness while maintaining a tough core, providing an optimal balance between wear life and impact resistance.
We offer complete flexibility in tooth count, ranging from 20 to 120 teeth, and can tailor tooth profiles, pressure angles, and module sizes to your specific design requirements. Each gear undergoes rigorous quality checks at every stage — from raw material inspection to final dimensional verification — ensuring compliance with your technical specifications.
Key Features & Technical Specifications:
- Integral (one-piece) design – no welding or assembly, maximizing structural integrity.
- Material: 20CrMnTi – alloy steel with high hardenability and impact toughness.
- Heat treatment: Quenching + tempering – achieves surface hardness of HRC 58–62 (customizable).
- Tooth range: 20–120 teeth – custom profiles available (involute, cycloidal, etc.).
- Module range: customizable according to your application (typical 2–20).
- Precision grade: up to DIN 6–8 or equivalent (available upon request).
- Surface finishing: shot blasting, black oxide, or as specified.
| Parameter | Value / Customization |
| Material | 20CrMnTi (equivalent to 20CrMnTiH) |
| Number of teeth | 20 – 120 (custom) |
| Heat treatment | Quenching (oil/water) + tempering |
| Surface hardness | HRC 58–62 (adjustable) |
| Tooth profile | Involute standard (others available) |

The quenching treatment we apply is precisely controlled to achieve the desired hardness without compromising core toughness. This ensures the gear can withstand high impact loads and resist surface pitting even under continuous heavy-duty operation. Our manufacturing process includes advanced CNC gear hobbing and shaving machines, supported by in-house heat treatment facilities, guaranteeing consistent quality from batch to batch.
Customer Benefits:
- Longer service life – reduced downtime and maintenance costs.
- Customized fit – exactly matches your existing gearbox or drive system.
- Competitive pricing – direct from factory with no middlemen.
- Fast turnaround – typical lead time 30–45 days for custom orders.
- Global logistics – shipped from Shanghai, Lianyungang, Qingdao, or Tianjin ports.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ) for custom integral ring gears?
A: Our MOQ typically starts at 1 piece for custom designs, as we understand the need for prototypes and small-batch testing. For larger series production, we offer competitive pricing based on quantity.
-
Q: Can you supply gears with teeth outside the 20–120 range?
A: While our standard customization covers 20–120 teeth, we can discuss special requirements on a case-by-case basis. Please provide your detailed drawing or specifications, and our engineers will evaluate feasibility.
-
Q: How do you ensure the quality of the quenching treatment?
A: We use programmable heat treatment furnaces with precise temperature and time control. Each batch is tested for surface hardness and microstructure to ensure conformity with your specified hardness range (e.g., HRC 58–62).
-
Q: Is the gear material 20CrMnTi equivalent to any international standard?
A: Yes, 20CrMnTi is similar to grades such as 20MnCr5 (DIN) or SAE 8620 (after appropriate heat treatment). We can provide material certificates and chemical composition reports upon request.
-
Q: What is the typical lead time for a custom order?
A: For a standard custom ring gear (material, teeth, quenching), lead time is approximately 30–45 working days from final drawing approval. Urgent orders may be expedited with prior agreement.
-
Q: Do you provide drawings or do we need to supply them?
A: We prefer to work from customer-supplied 2D/3D drawings for accuracy. If you need design assistance, our engineering team can help develop the gear profile based on your application parameters (torque, RPM, axis distance, etc.).
-
Q: Can the integral ring gear be supplied with additional machining (keyways, bolt holes, etc.)?
A: Absolutely. We can integrate features such as keyways, mounting holes, or special chamfers according to your drawing. Please specify all requirements clearly in your inquiry.
-
Q: What payment and shipping methods do you accept?
A: We accept T/T, L/C, and other common terms. Shipping is done via sea freight from major Chinese ports (Shanghai, Qingdao, Tianjin, Lianyungang). We can also arrange door-to-door delivery for many destinations.
