42CrMo Alloy Steel Gear Ring, Hardened Teeth, Modulus 2-6, Precision Machined for Industrial Gearboxes
Product Spotlights
Welcome to Henan San Kuang Machinery Technology Co., Ltd. – a professional manufacturer of precision-engineered power transmission components. Our 42CrMo Alloy Steel Gear Ring is designed to meet the rigorous demands of industrial gearboxes, offering exceptional strength, durability, and precision. With hardened teeth and a modulus range of 2-6, this gear ring delivers reliable performance under heavy loads and high torque conditions. Backed by our state-of-the-art 10,000-30,000 sqm factory and ISO9001-certified quality management system, we ensure every gear ring is manufactured with strict tolerance control and superior surface finish.
Key Features & Technical Specifications
- Superior Material: 42CrMo alloy steel provides high tensile strength, excellent fatigue resistance, and good hardenability, making it ideal for heavy-duty gear applications.
- Hardened Teeth: Induction or carburizing hardening process achieves a surface hardness of HRC 50-55, ensuring long service life and wear resistance even under continuous operation.
- Modulus Range 2-6: Flexible design allows customization for various gearbox requirements. Standard modulus options include 2, 2.5, 3, 4, 5, 6, with custom sizes available upon request.
- Precision Machined: CNC hobbing, gear grinding, and shaving ensure AGMA 8-10 quality grade, with tooth profile accuracy within 0.02 mm. Backlash and runout are tightly controlled for smooth meshing.
- Versatile Applications: Suitable for industrial gearboxes in mining, cement, steel, wind power, and heavy machinery sectors.
- Customizable Dimensions: Outer diameter, bore, keyway, and face width can be tailored to your specific requirements. We produce single-piece to batch orders.

Frequently Asked Questions
-
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 piece for standard sizes, but we can accommodate small trial orders for custom specifications. -
Q: Can you provide samples for testing?
A: Yes, sample orders are available. Sample cost and shipping will be discussed based on your requirements. -
Q: How do you ensure the hardness of the teeth?
A: We use induction hardening or carburizing + quenching processes, followed by tempering. Hardness is verified with Rockwell testers on every batch. -
Q: What is the typical lead time for a custom gear ring?
A: For custom sizes (modulus, diameter, bore), lead time is 20-35 working days after drawing approval. Standard sizes are 15-20 days. -
Q: Do you export to my country?
A: We ship to all major ports including Shanghai, Lianyungang, Qingdao, and Tianjin. Our main markets cover North America, South America, Europe, Asia, Africa, and Oceania. Please confirm with our sales team for specific destinations. -
Q: Can you provide certificates of material and heat treatment?
A: Yes, we can supply mill test certificates (MTC) for 42CrMo material and heat treatment reports upon request. -
Q: What payment terms do you accept?
A: We accept T/T, L/C, and sometimes Western Union for small orders. Regular terms: 30% deposit, 70% before shipment. -
Q: Is the gear ring suitable for high-speed applications?
A: For high-speed applications, we recommend our precision ground versions with dynamic balancing. Our standard hardened gear ring is designed for medium to heavy loads at moderate speeds. Please consult our engineers for specific conditions.
