Henan San Kuang Machinery Technology Co., Ltd. is a professional manufacturer specializing in non-standard precision gear production. With our state-of-the-art grinding facility and a dedicated team of 51-100 skilled employees, we deliver precision grinding services that guarantee tolerances as tight as 0.02 mm, fully compliant with international standards. Whether you need a single prototype or mass production, our factory, spanning 10,000-30,000 square meters in Luoyang, Henan, China, ensures every gear meets your exact specifications. Our annual export value of US$2.5-5 million across North America, South America, Europe, Asia, and Africa reflects the trust global clients place in our quality and service.
We understand that standard gears don’t always fit unique applications. That’s why we specialize in non-standard precision gears — from custom tooth profiles, unusual modules, to specialized materials. Our precision grinding process achieves a tolerance of 0.02 mm, ensuring smooth operation, low noise, and extended service life for your equipment.

Frequently Asked Questions (FAQ)
-
What does “non-standard precision gear” mean?
Non-standard gears are custom-designed gears that do not conform to standard module, tooth count, or profile specifications. They are manufactured according to customer drawings or specific application requirements. Our service covers any unique gear you need. -
Can you achieve a tolerance tighter than 0.02 mm?
Yes, for special applications we can achieve tighter tolerances (e.g., 0.01 mm) after evaluation. Please provide your design specifications and we will advise accordingly. -
What materials do you work with?
We commonly use carbon steel (45#), alloy steel (40Cr, 20CrMnTi, 42CrMo), stainless steel (304, 316), and other materials as per your request. We also offer material recommendations based on your operating conditions. -
What is the maximum gear size you can produce?
Our standard maximum outside diameter is 1,200 mm. For larger gears (up to 2,000 mm or more), we can discuss custom solutions with extended lead times. -
Do you provide heat treatment services?
Yes, we offer a full range of heat treatments including carburizing, quenching, tempering, and nitriding to achieve the required hardness and durability. -
How do you ensure quality control?
We perform 100% inspection using CMM, gear measuring centers, hardness testers, and run-out testers. A detailed inspection report is provided with every shipment upon request. -
What are your typical lead times?
Lead time depends on complexity and quantity. For prototypes, it usually takes 15-25 working days. For production orders, 30-45 working days. Express service is available for urgent projects. -
Can you ship to my country?
Absolutely. We ship globally via major ports: Shanghai, Lianyungang, Qingdao, Tianjin. Our logistics team handles all export documentation and ensures safe packaging.
