Henan San Kuang Machinery Technology Co., Ltd. proudly presents our Case-Hardened Toothed Ring Gear 20CrMnTi for Mining Equipment. As a professional manufacturer established in 2014 with a 10,000-30,000 m² factory and an annual export value of US$2.5-5 million, we specialize in producing high-durability ring gears designed for the most demanding mining environments. Our ring gears are engineered from 20CrMnTi alloy steel and undergo a precise case-hardening process, delivering exceptional wear resistance and torque transmission. This product is the reliable core component for your mining machinery, ensuring long service life and reduced downtime.
The 20CrMnTi material is specifically chosen for its excellent balance of toughness and surface hardness after carburizing. The tooth profile is cut with high precision, and each gear is heat-treated to achieve a case depth of 1.5-2.5 mm with a surface hardness of HRC 58-62. The core remains tough to absorb shock loads. Below are key technical specifications:
| Parameter | Value |
| Material | 20CrMnTi (equivalent to 20CrMnTiH) |
| Hardness (case) | HRC 58-62 |
| Core hardness | HRC 30-40 |
| Case depth | 1.5-2.5 mm (customizable) |
| Module range | 8 – 20 (or as per drawing) |
| Max outer diameter | Up to 3000 mm |
| Precision grade | ISO 8-9 (higher available) |
| Tooth profile | Involute (standard or modified) |
Key Features & Benefits:
- Superior wear resistance: The case-hardened layer withstands abrasive particles and heavy loads common in mining, extending gear life by 30-50% compared to untreated gears.
- High impact toughness: The 20CrMnTi core provides excellent ductility, preventing tooth breakage under sudden shock loads.
- Customizable dimensions: We offer flexible tooth count, module, and inner/outer diameter to match your specific equipment (e.g., ball mills, crushers, bucket wheel excavators).
- Precise machining: CNC gear hobbing and grinding ensure consistent tooth spacing and low noise operation.
- Heat treatment control: We use advanced carburizing furnaces with precise temperature and carbon potential control, ensuring uniform case depth and hardness.
- Quality assurance: Each gear undergoes hardness testing, magnetic particle inspection, and dimensional verification before shipment.
The ring gear is typically used in large mining equipment such as rotary kilns, grinding mills, and conveyor drives. Its robust design reduces maintenance frequency and improves overall equipment efficiency. For example, a mining company using our ring gears reported a 20% increase in uptime after replacing their original gears. With our factory's 51-100 skilled employees and fully equipped production lines, we can deliver consistent quality batch after batch.
Our company is committed to excellence. We hold multiple management system certifications including ISO9001, ISO14000, OHSAS18001, SA8000 and others (such as TL900, QS9000, ISO16949) which reflect our dedication to quality, environment, and social responsibility. Our products are exported to North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East. We operate from our base in Luoyang, Henan, China, with convenient access to ports of Shanghai, Lianyungang, Qingdao, and Tianjin.
We invite you to experience the durability and performance of our case-hardened toothed ring gear. Whether you need a standard design or a fully customized solution, our engineering team is ready to assist. Contact us today for a quote or technical consultation. Let us be your trusted partner in mining equipment components.
Frequently Asked Questions
-
What is the typical lead time for a custom ring gear?
For standard sizes, lead time is 30-45 days after drawing approval. For complex custom designs, it may extend to 60 days. We can expedite urgent orders upon request. -
Can you provide ring gears with different hardness levels?
Yes, we can adjust the case depth and core hardness to meet your specific application requirements. Please provide your load and wear conditions. -
What is the minimum order quantity (MOQ)?
Our MOQ is 1 piece for custom orders, but volume discounts are available for batch orders. -
Do you offer heat treatment certification?
Yes, we provide hardness test reports, case depth measurement records, and metallurgical analysis upon request. -
How do you ensure the gear fits my existing equipment?
We work from customer-supplied drawings or we can reverse-engineer your worn gear. We recommend providing key dimensions: outer diameter, inner diameter, tooth count, module, and face width. -
What surface treatments are available for corrosion protection?
Standard options include black oxide, phosphating, and anti-rust oil coating. Special coatings like zinc plating or Dacromet are available at extra cost. -
Can you produce ring gears with non-standard tooth profiles?
Yes, we can manufacture modified involute profiles, cycloidal, or other special profiles as per your design. -
Do you export to my country?
We export globally. Our main markets include North America, South America, Europe, Southeast Asia, Africa, and Oceania. We have experience with export documentation and logistics.
