Function and Benefits
The main bearing shell supports the crankshaft as it spins within the engine block. As a result, it:
- Provides a stable, low-friction surface for smooth crankshaft operation.
- Absorbs and distributes the forces created during combustion.
- Prevents direct metal-to-metal contact that can lead to severe engine damage.
- Maintains proper oil clearance for consistent lubrication.
These functions ensure your engine runs reliably and quietly, while also extending the lifespan of its moving parts.
