As a professional manufacturer from Henan San Kuang Machinery Technology Co., Ltd., we are proud to present our Bevel Gear Set AISI 4140 Quenched and Tempered Module 3 20:20 Teeth 1:1 Ratio. This precision-engineered gear set is designed for reliable power transmission in demanding industrial applications. Combining high-strength AISI 4140 alloy steel with quenched and tempered heat treatment, our bevel gears deliver exceptional durability, wear resistance, and consistent performance. With a 1:1 ratio and Module 3 tooth profile, this gear set offers smooth meshing and efficient torque transfer, making it an ideal choice for gearboxes, differential drives, and various mechanical systems. Backed by our 10,000-30,000 m² factory and experienced team, we ensure strict quality control and on-time delivery worldwide.
Key Product Features & Technical Specifications
- Material Excellence: Made from AISI 4140 chromium-molybdenum alloy steel, known for its high tensile strength, toughness, and fatigue resistance. Ideal for heavy-load applications.
- Heat Treatment: Quenched and tempered to achieve a hardness range of 28-32 HRC (customizable upon request), providing an optimal balance between hardness and ductility.
- Precision Cut Teeth: Each gear tooth is hobbed or milled to exact specifications, ensuring DIN 6-7 grade accuracy for low noise, minimal vibration, and efficient power transmission.
- 1:1 Ratio & Module 3: The 20:20 teeth configuration gives a direct 1:1 speed ratio, commonly used for right-angle drives. Module 3 offers a robust tooth profile suitable for moderate to high torque.
- Versatile Compatibility: This bevel gear set can be used with standard shafts and housings; optionally we can provide customized bore sizes, keyways, and surface treatments to fit your specific application.
- Surface Options: Available with black oxide, phosphating, or simple oiled finish to resist corrosion and extend service life.
- 100% Inspection: Each gear set undergoes dimensional check, hardness test, and meshing test before shipping, ensuring reliable performance.

Beyond the standard specifications, our bevel gear set is engineered to deliver tangible benefits to your application. The high core toughness from the quenched and tempered process ensures the gears can withstand shock loads and cyclic stresses without cracking. The precision tooth geometry reduces backlash and operating noise, which is critical in applications like machine tools, packaging equipment, and agricultural machinery. Additionally, the 1:1 ratio allows for simple design integration when you need to change the direction of rotation without altering speed or torque. Custom modifications such as special bore diameters, keyway dimensions, or alternative materials are available to meet unique project requirements. Our engineering team can also advise on optimal lubrication and mounting practices to maximize gear life.

Frequently Asked Questions (FAQ)
-
What is the typical lead time for this bevel gear set?
For standard stock items, lead time is approximately 15–20 working days. Custom orders may require 25–35 days depending on complexity. We will confirm at the time of order. -
Can you provide a different hardness level than 28–32 HRC?
Yes, the hardness can be adjusted by modifying the tempering process. Please specify your required hardness range, and we will evaluate feasibility. -
Is the gear set supplied with keyways and bores finished to my dimensions?
We can supply the gears with finished bores and keyways according to your drawings. If no drawing is provided, we will supply with standard bore (e.g., 25mm) and keyway, or leave them as blanks for you to machine. -
Do you offer certificates of material or heat treatment?
Yes, we can provide material test certificates (MTC) and heat treatment reports upon request. Please mention this requirement when placing the order. -
What is the maximum torque this gear set can handle?
Torque capacity depends on operating conditions, lubrication, and mounting. For typical industrial use with proper lubrication, this Module 3 1:1 set can handle up to approximately 150–250 Nm (estimated). We recommend contacting our engineers for a detailed calculation based on your application. -
Can you produce bevel gears with a different module or tooth count?
Absolutely. We specialize in custom gear manufacturing. You can provide your specifications (module, teeth, pressure angle, etc.), and we will produce accordingly. Minimum order quantity may apply. -
How are the gears packaged for export?
Each gear set is individually wrapped with anti-rust paper and placed in a strong wooden box or carton with cushioning. Bulk orders can be palletized or crated to ensure safe transport. -
Do you provide samples before mass production?
Yes, we can produce pre-production samples for your approval. Sample cost is negotiable and will be credited back in the mass production order.
