A big end bearing, also known as a connecting rod bearing, is a crucial component in a car's engine. It plays a significant role in connecting the engine's crankshaft to the connecting rod. The big end bearing is situated between the crankshaft's journal and the connecting rod's bottom end. Its primary function is to support the rotational movement of the crankshaft and allow the connecting rod to move smoothly, thereby converting linear piston motion into rotary motion.

This bearing works under extreme conditions, withstanding high loads and friction caused by the reciprocating motion of the pistons. It is usually made of durable materials like steel or aluminum alloy, and it is designed with a layer of lubricant, such as engine oil, to reduce the friction between the surfaces of the bearing and the journal. The big end bearing plays a crucial role in ensuring proper engine performance and preventing excessive wear and damage to the engine components.
