Threaded Adjusting Ring M135
The Threaded Adjusting Ring M135 is designed to set precise bearing preload and maintain correct gear alignment inside the differential.
Manufactured from hardened, wear-resistant steel, this adjusting ring ensures stable positioning of differential components under heavy load and continuous operation. Its fine, accurately machined threads allow controlled adjustment, helping technicians achieve the correct backlash and preload settings. The robust construction prevents deformation, ensuring long-term accuracy even in demanding commercial usage.
By keeping gears and bearings correctly aligned, the adjusting ring reduces noise, minimizes wear, and enhances overall drivetrain efficiency. It plays a vital role in ensuring smooth power transfer, reliable differential operation, and extended service life in commercial diesel vehicles.
Key Features
- Precision-threaded adjusting ring (M135 size)
