Products Description

steel spiral bevel gears
Spiral bevel gears are among the most critical components in transmission systems, primarily used to achieve power transfer between intersecting shafts. With 20 years of manufacturing expertise, our factory produces spiral bevel gears characterized by superior load-bearing capacity, smooth transmission efficiency, and minimal operational noise. These products are widely utilized in automotive, construction machinery, mining equipment, and industrial automation sectors.
Technical Highlights
Hardness Gradient:
Through precise carburizing, we ensure high surface wear resistance while maintaining core toughness to prevent brittle fracture under impact loads.
Distortion Control:
With 15 years of export experience, we strictly predict heat treatment distortion and compensate through finishing (like grinding), ensuring accuracy up to DIN 5-8.
Precision Verification:
Every year, we conduct third-party calibration of our metallographic analyzers and hardness testers to ensure that every Material Test Report (MTR) provided to our clients is authentic and reliable.
