Kean gears achieve a maximum precision of GB Grade 4, complying with international standards such as ISO, DIN, and AGMA. They are widely used in demanding sectors like aerospace, rail transit, mining, metallurgy, and industrial automation. Utilizing ZEISS CMMs (Germany) and Gleason 1500GMM inspection centers (USA), every product undergoes rigorous quality verification.

We specialize in manufacturing bevel gears, cylindrical gears, transmission shafts, and internal ring gears, among others. Our capabilities cover a module range of 0.5-20, with a maximum milling diameter of 1720mm, a maximum grinding diameter of 850mm, and transmission ratios from 1:1 to 1:10, meeting large-volume, high-precision requirements.

We support a wide range of processes, including internal and external straight teeth (spur teeth), helical teeth, herringbone gears, splines, CBN grinding (minimum diameter Ø13mm, module 0.5), and carburizing/nitriding heat treatments. These capabilities allow us to meet complex geometric and extreme operating condition requirements.

Kean produces over 35,000 high-precision gears annually. Our facility is equipped with Gleason Phoenix 275G/800G CNC spiral bevel gear grinders (USA), KAPP VX55/VX59 gear grinding centers (Germany), and MAAG KS42 high-precision gear grinders (Switzerland). This ensures efficient, large-volume production to meet global customer demands.

We support orders starting from just 1 piece. For urgent orders, the delivery time can be shortened to 30 days, while standard ground gear orders typically deliver within 45-60 days. Our complete industrial chain and regional manufacturing capabilities enable quick spare parts support, ensuring seamless project progression for our clients.

All gear products come with a 3-year warranty, with free replacement for any quality issues not caused by gear design. Our commitment to reliable quality is backed by certifications including GB/T19001-2016, ISO9001:2015, AS9100D, and Classification Society Approvals.

Yes, we support PPAP (Production Part Approval Process) and other high-level quality submissions. Leveraging over 30 patented technologies and a complete Ipsen heat treatment production line (Germany), we possess capabilities for ultrasonic testing, magnetic particle testing, and gear tooth grinding burn detection, ensuring large-volume products meet client standards.

Yes, Kean specializes in large-volume custom non-standard gear manufacturing. Equipped with GROB 5-axis universal machining centers (Germany), we can efficiently produce gears based on specific customer requirements (materials, surface treatments, transmission ratios), meeting the stringent demands of industries like aerospace.

Compared to competitors from Europe and America, Kean gears offer both exceptional precision (Grade 4) and competitive pricing. Drawing on 23 years of experience and an efficient supply chain, we provide high-value, large-volume solutions for our customers.
