What is rod bearings?

Rod bearings are a critical component of an internal combustion engine. They are located between the crankshaft and connecting rods and they support the weight of the crankshaft while allowing it to spin freely.

Rod bearings consist of a metal shell and a lining made of a soft bearing material, such as bronze or aluminum. The bearing material is designed to absorb and distribute the force of the crankshaft as it rotates, reducing friction and wear.

Over time, rod bearings can wear out due to excessive heat, lack of lubrication, or normal wear and tear. This can cause a knocking or rattling noise in the engine and can ultimately lead to engine failure if not addressed.

Regular maintenance, including oil changes and inspections of the bearings, can help prolong the life of the bearings and the engine as a whole. Some modern engines use more advanced materials for their bearings, such as ceramic or polymer coatings, to improve durability and reduce friction.
