Rotary Shaft Seal Pinion
The Rotary Shaft Seal Pinion prevents oil leakage from the differential pinion shaft while keeping contaminants out.
This seal is engineered with high-quality rubber and metal reinforcement to withstand rotational friction, pressure changes, and continuous exposure to gear oil. Its precision sealing lip ensures a tight, leak-free fit around the pinion shaft, maintaining proper lubrication inside the differential housing. The durable construction resists heat, wear, and deformation, ensuring long service life even under heavy-duty operating conditions.
By ensuring proper sealing, the pinion shaft seal protects gears and bearings from oil loss and contamination. This helps maintain smooth differential operation, reduces wear, and prevents costly drivetrain damage in commercial diesel vehicles.
Key Features
- High-quality pinion shaft oil seal
- Prevents gear oil leakage and contamination

FAQ
What does the pinion shaft seal do?
It prevents oil leakage from the differential pinion area and blocks contaminants from entering.
When should it be replaced?
When oil leaks appear near the pinion flange or when noise and lubrication issues arise.
