Shaft Lip Type Seal / Crankshaft RR
The Shaft Lip Type Seal / Crankshaft RR is a high-performance sealing component designed to prevent oil leakage at the rear end of the crankshaft. It ensures a tight, reliable seal under continuous rotation, high engine speeds, and varying temperature conditions, making it essential for heavy-duty commercial vehicle engines.
Constructed from premium heat- and oil-resistant elastomers, the seal features a precision-formed lip that maintains strong contact with the crankshaft surface while reducing friction. Its reinforced design helps maintain consistent sealing pressure, preventing oil loss and contamination of the clutch housing area.
This rear crankshaft seal supports long-term engine reliability by maintaining proper lubrication, minimizing oil consumption, and protecting internal engine components from wear and overheating.
Key Features
- High-temperature, oil-resistant elastomer construction
- Precision-designed sealing lip for reliable leak prevention
- Reduces friction while maintaining strong shaft contact
- Prevents oil contamination in the clutch housing
- Long-lasting performance under high-speed rotation
- Ideal for heavy commercial engine applications
