Our advanced capabilities enable a wide range of specialized grinding and machining processes:
Leveraging 23 years of high-precision gear manufacturing experience, Kean specializes in high-volume custom gear solutions. Backed by globally leading equipment, over 30 patented technologies, and a scalable production capacity exceeding 35,000 non-standard parts annually, we provide clients with high-precision, cost-effective custom gears that meet the most stringent transmission requirements.
Our core business involves customization based on customer-provided drawings and reverse engineering from physical samples. If you need custom gears or gear sets, Kean's engineers offer the necessary expertise to propose solutions that meet or exceed your exact specifications.
All our gear products come with a 3-year warranty, and we offer free replacement for any quality issues not caused by gear design. Our commitment to reliable quality is guaranteed by certifications including GB/T19001-2016, ISO9001:2015, AS9100D, and Classification Society approvals.
Kean manufactures straight and spiral bevel gears, spur and helical cylindrical gears, internal gears, gear shafts and splined shafts for customer‑specific transmission requirements.
Yes. Kean manufactures custom gears and gear components to customer‑supplied drawings, 3D models, technical specifications, and agreed inspection requirements.
Yes. Customers may provide an authorized physical sample, along with available operating or application information, for a preliminary engineering review. We will confirm project feasibility and any additional technical information required for quotation on a case‑by‑case basis.
For a custom gear quotation, customers are encouraged to provide a drawing, 3D model, or authorized physical sample, together with as much information as possible on gear type, material, heat treatment, required accuracy, quantity, inspection requirements, and application. After engineering review, Kean may request additional technical information as needed.
Kean's current inspection capabilities include gear measurement, coordinate measuring machine (CMM) inspection, material and mechanical testing, ultrasonic testing (UT), magnetic particle testing (MT), and grinding burn inspection. The inspection scope and required documentation are determined according to the requirements of each project.
