Henan San Kuang Machinery Technology Co., Ltd. is proud to offer our Precision-Machined 20CrMnTi Steel Gear Ring, Module 3, Hardness HRC 58-62, for Industrial Gearboxes. As a dedicated manufacturer with a factory spanning 10,000–30,000 square meters and exporting to markets across the globe — including North America, Europe, Southeast Asia, and Oceania — we have engineered this gear ring to meet the highest demands of heavy-duty industrial applications. Our gear ring combines exceptional material properties with advanced precision machining, delivering reliable performance and extended service life for your gearbox systems. Whether you are upgrading existing equipment or building new machinery, this gear ring is designed to optimize efficiency and reduce maintenance costs.
Key Features & Technical Specifications
- Premium Material – 20CrMnTi Alloy Steel: This low-carbon alloy steel is specifically chosen for its excellent carburizing response, high core toughness, and superior wear resistance. After heat treatment, it achieves a hard case with a tough core, ideal for gear components subjected to cyclic loading and high contact stresses.
- Precision Machined to Close Tolerances: Our gear rings are manufactured using state-of-the-art CNC gear hobbing and grinding equipment, ensuring tooth profile accuracy and consistent module dimensions. Typical achievable precision is DIN 6–7, with customization available for tighter tolerances.
- Controlled Hardness HRC 58–62: Through optimized carburizing and quenching processes, we achieve a uniform case hardness of 58–62 HRC. This hardness range provides an excellent balance between wear resistance and fatigue strength, preventing premature tooth failure.
- Module 3 Design for Medium-Load Applications: The module 3 tooth size is widely used in industrial gearboxes for moderate torque transmission. This gear ring is suitable for parallel shaft, planetary, and bevel gearbox configurations.
- Customizable Dimensions & Additional Processing: Outer diameter, inner diameter, tooth count, keyway, and surface treatments (such as blackening or phosphating) are all available based on your drawing or specifications. We also support optional shot peening for improved fatigue life.

Why Choose Our Gear Ring for Your Industrial Gearbox?
- Enhanced Durability & Life: The combination of 20CrMnTi material and controlled heat treatment significantly resists pitting, scuffing, and tooth breakage — common failure modes in gearboxes. This means fewer replacements and lower total cost of ownership.
- Quiet & Smooth Operation: Precision tooth profile and consistent module ensure meshing with minimal backlash and vibration, contributing to quieter gearbox performance even under heavy loads.
- Flexible Customization: We understand that every gearbox design is unique. Our engineering team can work with your drawings to produce gear rings with specific inner diameters, keyways, mounting holes, or special tooth modifications (e.g., tip relief, crowning).
- Rigorous Quality Control: Each gear ring undergoes dimensional inspection (profile, pitch, runout) and hardness testing (Rockwell on case and core). We also offer optional non-destructive testing (magnetic particle or ultrasonic) upon request.
- Sustainable Supply: As an established manufacturer with an annual export value of US$2.5–5 million, we maintain stable production capacity and can handle both small prototype orders and large-volume contracts. Lead times are competitive.

Frequently Asked Questions (FAQ)
Q1: Why is 20CrMnTi steel used for this gear ring?
A: 20CrMnTi is a widely recognized carburizing steel in the gear industry due to its excellent hardenability, high core toughness, and good wear resistance after heat treatment. It offers a superior balance of strength and ductility, making it ideal for gear rings subjected to high contact stresses and cyclic loading.
Q2: How do you ensure the hardness is consistent at HRC 58–62?
A: We use precise furnace control during carburizing, quenching, and tempering. Each batch is tested with a Rockwell hardness tester on both the case and core, and we maintain strict records. Process validation samples are also checked periodically.
Q3: What is the minimum order quantity (MOQ)?
A: For standard gear rings, the MOQ is typically 10 pieces. For customized designs, the MOQ may vary based on complexity and tooling requirements. Please contact us with your specific needs for a tailored solution.
Q4: What is the typical lead time?
A: Lead time depends on quantity and customization level. For standard dimensions, it is usually 15–25 working days. For complex custom orders, allow 20–35 working days. Rush orders may be available upon request.
Q5: Can you produce gear rings with non-standard tooth modifications, such as tip relief or profile crowning?
A: Yes, we can manufacture gear rings with specific tooth modifications to optimize noise, vibration, and load distribution. Please provide your design requirements, and our engineering team will advise on feasibility.
Q6: Do you offer surface treatments for corrosion resistance?
A: Yes, we offer optional surface treatments such as black oxide (blackening) and phosphating. These processes provide a protective layer against light corrosion and can also improve oil retention during lubrication.
Q7: What packaging do you use for export shipment?
A: We pack each gear ring individually with anti-rust paper, plastic film, and secure wooden crates or pallets to prevent damage during transit. Additional packaging options (e.g., vacuum packing) are available upon request.
Q8: Do you provide samples before mass production?
A: Yes, we offer sample production for approval. The sample cost is normally charged and refundable or deducted from the first bulk order. Lead time for samples is typically 10–15 working days.
