Radial Seal Input Thru Shaft
It maintains a tight and consistent seal around the rotating shaft, ensuring stable lubrication inside the transmission and preventing dust, moisture, and dirt from entering. Made from premium elastomer with a reinforced metal structure, the seal delivers excellent resistance to heat, pressure, and continuous rotational movement. Its optimized lip design ensures long-lasting performance even under harsh operating conditions.
By maintaining proper sealing, the input thru shaft seal helps extend transmission life, improve efficiency, and reduce maintenance requirements. It ensures smooth gear shifting and consistent drivetrain performance in heavy-duty commercial vehicles.
Key Features
- High-quality radial seal for gearbox input shaft
- Prevents oil leakage and blocks contaminants
- Heat-resistant and wear-resistant elastomer construction
- Ensures stable lubrication and smooth transmission operation
- Designed for long service life under heavy-duty conditions
