What is main cap bearings?

Main cap bearings are a type of engine bearing that are located between the engine block and crankshaft. They provide support, reduce friction and wear, and maintain the proper alignment between the crankshaft and engine block. Main cap bearings are typically made of a durable material like steel and coated in a layer of bearing alloy, which is designed to withstand the high heat and pressure generated by the engine. They come in a variety of sizes and styles to accommodate different types of engines and can be replaced as needed during engine maintenance or repair. Proper maintenance and replacement of main cap bearings is essential to ensure the longevity and performance of an engine.
