Cam Bearing STD for Mack MP8 & Volvo D13 Engines Replaces 20999623 | F012077

About this Item

• Support: Our Camshaft bearings provide a stable and secure mounting point for the camshaft within the engine block. The camshaft rotates at half the speed of the crankshaft and operates the engine's valves, controlling the intake and exhaust processes. The bearings ensure that the camshaft remains properly aligned and supported during operation, even under high loads and at high engine speeds.
• Reduce Friction: The surface of our camshaft bearings is designed to reduce friction between the camshaft and the engine block. This is essential for smooth operation and to prevent excessive wear on both the camshaft and the engine block. Reduced friction also helps to improve fuel efficiency and overall engine performance.
• Dissipate Heat: During operation, the camshaft generates heat due to friction and mechanical stress. Ours help to dissipate this heat by providing a pathway for thermal energy to transfer away from the camshaft and into the engine block. Proper heat dissipation is critical for preventing overheating and ensuring the longevity of engine components.
• Alignment: Our Camshaft bearings help to maintain the correct alignment of the camshaft within the engine block. This is essential for precise timing of the engine's valve operation, which directly affects combustion efficiency and power output. Proper alignment also reduces noise and vibration during engine operation.
