About Us
Built from the Ground Up to Make Better Gears
Over decades, the product range grew from standard spur gears into a comprehensive line of precision spiral bevel gears, helical bevel gear units, gear shafts, spline shafts, gear couplings, and complete gearbox assemblies. Today, roughly 50% of output is exported directly to North American and European markets, with key end customers that include JOHN DEERE and other globally recognized equipment manufacturers.

What We Manufacture
Spiral Bevel Gears
The flagship product line. Modules M0.5–M8 in standard production, up to M12 on request. OD up to 600mm. Precision DIN6–DIN9. Material grades from brass and aluminum for light-duty automation to 20CrMo and 18CrNiMo7-6 for heavy industrial drives.
Spiral angle: 35°–45° standardHelical Bevel Gear Units
Tangential bevel tooth geometry with greater coincidence degree than spur bevel gears. Particularly suited to high-speed industrial machinery, agricultural PTO drives, and automated machine tools. Manufactured to ISO H7/H8 bore tolerances.
Helix angle: 8°–50° on requestHypoid Bevel Gears
Offset axis design for vehicle differentials, low-profile industrial drives, and applications requiring a larger pinion diameter for increased torque capacity. Gear ratio up to 25:1 per stage. Always supplied as matched ring-and-pinion pairs.
Ratio range: up to 25:1Gear Shafts & Spline Shafts
Combined gear-and-shaft components including pinion shafts and gear drive shafts in 18CrNiMo7-6 and 20CrMo. Spline profiles to ISO H7/H8/H9. Used extensively in agricultural power transmission and construction machinery drive trains.
Spline ISO H7 · H8 · H9Gear Couplings & Assemblies
42CrMo gear couplings (Q&T HB 280–320) and complete planetary gearbox assemblies (nitrided, DIN7 grade) for robotics, construction machinery, and renewable energy applications. Full assembly and test service available.
Material: 42CrMo · Q&T HB280–320Straight Bevel Gears & Custom Types
Straight bevel, miter, zero-degree bevel, and custom non-standard geometries available on drawing. Suitable for low-speed, lower-noise-requirement applications. Brass straight bevel gears are available for printing machinery and precision instrument drives.
Non-standard accepted
What Sets Our Manufacturing Apart
When you're specifying spiral bevel gears for a critical drive application, the supplier's manufacturing capability matters as much as the component specifications. Here's how our facility compares on the criteria that matter most to engineering buyers.
Own Factory — No Subcontracting
250+ dedicated CNC machining centers, gear cutting machines, heat treatment furnaces, grinding equipment, and precision test instruments — all under one management. Consistent output, traceable process records, and accountability at every step.
Comprehensive QA Documentation
Chemical composition and mechanical performance reports, 100% ultrasonic test per EN10228-3 or SA388, original heat treatment curves, and CMM dimensional reports. Your incoming QC team will have everything they need.
Reverse Engineering & OEM Capability
No drawing? Send us your failed gear. Our engineering team will measure, reconstruct the geometry, select the correct material grade, and manufacture a replacement. We accept PDF, DXF, DWG, STEP, and IGES files for drawing-based production.
Proven Export Track Record
Over 50% of production ships to North America and Europe. We handle export documentation, international packaging standards, and logistics coordination. Tier-1 equipment manufacturers have relied on our supply chain consistency for over a decade.
Quality Certifications & Standards Compliance
From Raw Material to Precision Gear — Our Full Process
Understanding how we manufacture spiral bevel gears helps engineers evaluate whether our quality system matches their specifications. Here is our standard production flow.
Raw Material
Forged / rolled alloy steel. Chemical composition verified on receipt.
Blank Turning
CNC lathe pre-machines blank to profile dimensions. Annealing applied where required.
Gear Cutting
Face-milling (Gleason) or face-hobbing spiral bevel cutting. Spiral angle 35°–45°.
Heat Treatment
Carburizing + quenching to HRC 58–62 surface, HRC 35–42 core. Full curve documentation.
Grinding & Lapping
Hard grinding and profile modification for DIN6–DIN9. Paired sets lapped to achieve optimal contact pattern.
Final Inspection & Shipping
100% CMM dimensional verification. QA documentation compiled. Packed per international export standard.
