Features

• Maintains proper crankshaft positioning within the engine block
• Handles continuous rotational loads and pressure forces
• Operates effectively in limited lubrication environments
• Used during engine service and rebuild work

Construction

• Engineered using high-strength alloy materials to withstand stress
• Rollers are designed for resistance to pitting and surface fatigue
• Similar bearings may include plated or coated components for protection

Notes

Inspect crankshaft journals, bearing seats, and lubrication conditions during installation.
