As a professional manufacturer based in Luoyang, Henan, Henan San Kuang Machinery Technology Co., Ltd. specializes in producing high-precision CNC machined ring gears with an accuracy of 0.01mm. Our factory, spanning 10,000–30,000 square meters, is equipped with advanced 5-axis machining centers and gear cutting machines. We offer both forged and casted annular gears, fully customizable to your specific dimensions, materials, and surface treatments. With an annual export value of US$2.5–5 million, our products are trusted across North America, Europe, Southeast Asia, and beyond.
Our precision ring gear is designed for demanding industrial applications where reliability, durability, and exact tooth profile are critical. Whether you need a single prototype or mass production, we ensure consistent quality through rigorous in-house inspection using CMM and gear measuring centers. Each gear is manufactured under strict process control, from raw material selection to final machining.
Key Features & Technical Specifications
- High Accuracy: Achievable gear precision up to DIN 6–7 grade (0.01mm runout error).
- Material Options: Carbon steel (20CrMnTi, 42CrMo), alloy steel, stainless steel, or as per your requirement.
- Manufacturing Flexibility: Both forged (for higher strength) and casted (for complex shapes) available.
- Heat Treatment: Carburizing, nitriding, induction hardening to achieve surface hardness HRC 58–62.
- Custom Dimensions: Outer diameter from 100mm up to 3000mm, module 1–20, tooth count customizable.
- Surface Finishing: Shot blasting, black oxide, phosphating, or painting upon request.
- Full Traceability: All gears marked with serial number, material heat number, and inspection report.

Frequently Asked Questions
-
What is the minimum order quantity (MOQ)?
We accept both small quantities (1–5 pcs for prototypes) and large volume production. MOQ for standard orders is negotiable. -
Can you match existing gear dimensions and tooth profile?
Yes, we can reverse-engineer from a sample or drawing. Our engineering team will verify the parameters and produce matching gears. -
What is the typical lead time?
For custom gears, lead time ranges from 25 to 45 working days depending on complexity and quantity. Rush service is available upon request. -
Do you provide heat treatment and surface coating?
Yes, we offer carburizing, nitriding, induction hardening, black oxide, phosphating, and painting. Please specify in your inquiry. -
How do you ensure 0.01mm accuracy?
We use high-precision CNC gear hobbing and grinding machines, followed by 100% inspection with a gear measuring center and CMM. Our quality control system is robust. -
Can I get a sample before mass production?
Certainly. We can produce a pre-production sample for your approval. Sample cost is charged separately and refundable upon bulk order. -
What materials do you recommend for heavy load applications?
For high strength and wear resistance, we recommend 20CrMnTi or 42CrMo with carburizing and quenching. For stainless steel needs, we can use 304 or 316. -
Do you export to my country?
We regularly export to North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East. Our logistics team can handle customs documentation for most destinations.
