Material & Advantages

1. High-quality alloy steel blank with surface quenching treatment, high surface hardness, resistant to impact abrasion and indentation under continuous axial thrust

2. Double-sided ultra-precision flat grinding, excellent flatness, uniform contact stress to prevent local concentrated wear

3. Strict OEM outer diameter, inner bore and thickness dimension, direct assembly without grinding modification during gearbox overhaul

4. Optimized surface oil storage texture, continuously form lubricating oil film to reduce friction heat between pressure disc and sun gear end face

5. Stable limiting effect eliminates sun gear axial play, effectively lower abnormal vibration and grinding noise of planetary gear set

6. Adapt to long-distance full-load highway logistics, mountain heavy climbing and frequent low-range heavy transport working conditions

Application Scenarios
