Introduction
Camshaft bearings are crucial components in internal combustion engines, playing a vital role in the precise timing and smooth operation of the valvetrain. These bearings support the camshaft, which controls the opening and closing of the engine's intake and exhaust valves. Ensuring the longevity and optimal performance of camshaft bearings is essential for the overall efficiency and lifespan of the engine.
Understanding Camshaft Bearings
Camshaft bearings are typically cylindrical in shape and made of durable materials such as steel, aluminum, or copper alloys. They have an inner surface that fits around the camshaft and an outer surface that is housed in the engine block or cylinder head. The bearings provide support for the camshaft, reducing friction and allowing it to rotate smoothly.
