Product Features & Technical Specifications
- Standard Compliance: Manufactured in line with DIN, ISO, and AGMA standards (as specified). All gears undergo dimensional verification and hardness testing.
- High Strength & Wear Resistance: Made from premium alloy steel (20CrMnTi, 40Cr, etc.) with carburizing and quenching heat treatment – surface hardness reaches HRC 58–62.
- Smooth & Quiet Operation: Optimized helix angle design (15°–35°) reduces vibration and noise, ideal for high-speed transmission systems.
- Precision Machining: Gear hobbing and grinding achieve accuracy grade up to DIN 6. Custom grades (DIN 7–9) available upon request.
- Flexible Customization: Modules from 1 to 20 mm, outer diameter up to 2000 mm, and various tooth profiles (involute, modified).
- Surface Treatment Options: Shot blasting, phosphating, black oxide, or anti-rust coating for extended service life.
