Bronze split bearing is the contact part between sliding bearing and journal. It is a semi-circular cylindrical surface in the shape of a tile, which is very smooth. It is generally made of wear-resistant materials such as bronze and antifriction alloy. In special cases, it can be made of wood, engineering plastics or rubber.

There are two types of bearing shells: integral and split. The integral bearing bush is usually called Bushing. There are two types of integral bronze split bearing: oil groove and oil groove. The bearing bush and journal adopt clearance fit, and generally do not rotate with the shaft.
