Henan San Kuang Machinery Technology Co., Ltd. – Since our establishment in 2022, we have rapidly built a reputation for delivering high-quality power transmission components. Our Hardened Alloy Steel Precision Ring Gear, 20° Pressure Angle, Outer Diameter 500mm is engineered for demanding industrial applications where reliability and durability are non-negotiable. Manufactured in our 10,000–30,000 m² facility in Luoyang, China, this ring gear combines precision machining, advanced heat treatment, and strict quality control to ensure consistent performance. Customizable dimensions, material grades, and heat treatment options allow us to meet your specific requirements – whether for heavy machinery, wind turbines, or mining equipment.
Key Features & Technical Specifications
- Premium Hardened Alloy Steel – Made from high-strength alloy steel (e.g., 40Cr, 42CrMo) that undergoes quenching, tempering, or carburizing to achieve surface hardness of HRC 50–60, ensuring excellent wear resistance and long service life.
- Precise 20° Pressure Angle – Standard 20° pressure angle design ensures smooth meshing, reduced noise, and efficient power transmission. This angle is widely used in industrial gear drives for optimal load distribution.
- Outer Diameter 500 mm (Customizable) – The 500 mm OD is a common size for medium to large applications. We can adjust the outer diameter, inner diameter, tooth count, and face width to match your design specifications.
- High Precision Machining – Controlled gear hobbing and optional grinding processes achieve precision grades ISO 1328 Grade 7–9 (higher grades available on request), minimizing backlash and transmission errors.
- Customizable Heat Treatment – Choose from quenching & tempering, carburizing, or nitriding based on your hardness and toughness requirements. Surface hardness and core ductility are optimized for impact resistance.
- Versatile Applications – Suitable for use in ring gear drives, slewing bearings, planetary gearboxes, crushers, and heavy-duty transmission systems across multiple industries.
- Rigorous Quality Control – Each ring gear is inspected for dimensional accuracy, hardness, and gear geometry using calibrated instruments. Certificates of conformance and material test reports are provided upon request.

Frequently Asked Questions
-
Q: What materials are available for this ring gear beyond the standard hardened alloy steel?
A: We can also use carburizing steel (20CrMnTi), nitriding steel (38CrMoAl), or stainless steel upon request. Material selection depends on your hardness, corrosion resistance, and budget needs. -
Q: Can you customize the inner diameter and tooth count?
A: Yes. The outer diameter of 500 mm can be maintained while adjusting the inner diameter, tooth number, and tooth profile (involute or other) according to your design. Send us your drawing or parameters for a feasibility check. -
Q: What is the typical lead time for a batch of 100 pieces?
A: For standard specifications, lead time is approximately 30–45 days after order confirmation. Custom heat treatment or higher precision grades may require 5–10 extra days. We always communicate the production schedule in advance. -
Q: Do you provide heat treatment certificates and material test reports?
A: Yes. We can supply mill certificates for the raw steel, as well as hardness test reports and dimensional inspection records. Additional non-destructive testing (e.g., magnetic particle or ultrasonic) is available at an extra charge. -
Q: Is this ring gear suitable for use in a slewing bearing?
A: Absolutely. This ring gear can be integrated into slewing bearing assemblies for excavators, cranes, or wind turbines. We can also supply the matching raceway or rollers as a complete set if needed. -
Q: How do you ensure the gear meshes quietly and with low vibration?
A: Our precision hobbing and optional grinding produce a surface finish of Ra 0.8–1.6 µm. Together with the 20° pressure angle, the gear runs smoothly. For ultra-quiet applications, we can perform gear lapping or profile modifications. -
Q: Do you offer samples before mass production?
A: Yes. We can produce sample pieces for fit and performance testing. Sample cost is negotiable and will be deducted from the final order quantity. Shipping cost is at the buyer's expense. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, the MOQ is 10 pieces. For fully customized designs, we recommend a minimum of 5 pieces to amortize tooling and setup costs. Smaller quantities are possible upon discussion.
