Collection: Main Bearings
Main bearings are crucial components located between the engine crankshaft & the engine block. Their primary function is to support the crankshaft & reduce friction between the rotating crankshaft & the engine block. Main bearings are typically made of a durable & wear-resistant material, such as steel-backed aluminum alloy or tri-metal construction, to withstand the high loads & forces experienced during engine operation. They are designed to provide a smooth & low-friction surface for the crankshaft to rotate on, ensuring proper lubrication & preventing excessive wear & damage. Main bearings are available in various sizes & designs to fit specific engine applications. Upgrading to performance main bearings can provide enhanced durability & reliability, especially in high-performance or heavy-duty engines. Regular inspection & maintenance of main bearings are essential to check for signs of wear, damage, or loss of clearance, as worn or damaged main bearings can lead to catastrophic engine failure. Proper lubrication & oil quality are crucial for the optimal performance & longevity of main bearings, as they rely on a continuous supply of clean & high-quality engine oil to reduce friction & dissipate heat.
