Annual output is approximately 1,500 sets per year across different product categories, excluding general accessory components.

The company’s main products include large-diameter gears, cylindrical gears, spur gears, helical gears, double helical gears, ring gears, internal gears, bevel gears, spiral bevel gears, straight bevel gears, pinion shafts, gear shafts, spline shafts, spline couplings, machine spindles, and custom precision gearboxes. It also manufactures custom high-precision industrial gears, including matched bevel gear sets, planet gears, internal ring gears, and gear shafts.

Projects are primarily manufactured to customer drawings and mutually confirmed technical and quality requirements. Where technically feasible and within the company’s available inspection capability, selected sample-based projects may also be considered after measurement and feasibility review. Appropriate manufacturability and process optimization recommendations may be provided for customer confirmation.

Manufacturing capabilities include large CNC gear cutting, gear shaping, precision gear grinding, five-axis machining, turn-mill machining, and precision finishing. The maximum gear grinding diameter is approximately 2,500 mm, and the maximum module is approximately 45.

For applicable products, DIN Grade 4 may be achievable, while selected DIN Grade 3 requirements may be evaluated on a project-specific basis. AGMA Quality 12 may also be supported where applicable. Final achievable accuracy depends on the applicable standard, gear type, size, material, structure, heat treatment, manufacturing process, and technical review.

Inspection capabilities cover tooth profile, lead, pitch, radial runout, surface roughness, material composition, hardness, mechanical properties, ultrasonic testing, phased-array ultrasonic testing, grinding-burn inspection, micro-magnetic testing, large-component dimensional inspection, dynamic balancing, and bevel-gear rolling contact inspection.

According to the company, inspection records, material documents, gear accuracy reports, hardness records, non-destructive testing documents, and final inspection reports can be provided according to customer drawings, technical agreements, and project requirements.

The company exports approximately 15 percent of its output, serving customers in Europe, North America, Asia, Australia, and other international industrial markets. Application areas include industrial gearboxes, wind power, mining equipment, metallurgical equipment, cement machinery, power generation equipment, machine tools, railway and locomotive equipment, construction machinery, feed and biofuel machinery, canning machinery, and other heavy-duty industrial transmission systems.

For example, in the canning machinery industry, custom gearbox gears and transmission components are used in can-making equipment such as can necking machines, trimming machines, and conveyors. The products operate in continuous high-speed transmission systems under repeated cyclic loads, with requirements including controlled backlash and stable gear accuracy.

Market impact and end-use demand

Demand for high precision gears is visible in several end-markets. Asia-Pacific accounted for a 51 percent share of the wind turbine gearbox market in 2024, largely driven by installations in China, according to Data Insights Reports. The railway traction motor market was valued at USD 6.467 billion in 2024 and involves high-precision traction gears, according to Market Research Future.

Within the precision gearbox segment, planetary gearboxes represented 65.3 percent of market share in 2025, according to Grand View Research. These applications depend on gear accuracy, material traceability, and controlled heat-treatment and inspection procedures.


Selection considerations for procurement teams

For industrial equipment procurement, manufacturers are often compared on three criteria: accuracy capability, inspection transparency, and flexibility for custom or non-standard orders.

The manufacturers listed above serve different segments of the market, ranging from custom manufacturing primarily to customer drawings at Jiangsu New Yinye Transmission Electromechanical Co., Ltd. to system-level gearbox supply at Nanjing High Speed & Accurate Gear Group Co., Ltd. and standardized production at Wenling Juli Gear, Shenzhen Huayuexin Precise Ware, and Hebei Kexin Gear.


Outlook

In 2026, the Chinese supply chain for high precision gears remains characterized by large installed machining capacity, an expanding range of inspection methods, and a growing share of export-oriented custom gear manufacturing.

For custom and project-based transmission requirements, the availability of manufacturers that can work primarily to customer drawings and support project-specific high-precision requirements reduces dependence on standard off-the-shelf gear products.
