The bearing shell is the contact part between the sliding bearing and the journal. The shape is a tile shaped semicircular cylindrical surface, 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 kinds of bearing shells: integral and split. Integral bearing shells are usually called bearing sleeves. The integral bearing bush can be divided into two types: without oil groove and with oil groove. The bearing bush and journal adopt clearance fit and generally do not rotate with the shaft.
The material of bearing bush is characterized by small friction coefficient, sufficient fatigue strength, good running in performance and good corrosion resistance. Common bearing materials include bearing alloy (Babbitt alloy), copper alloy, powder metallurgy, gray cast iron and wear-resistant cast iron.
The materials of non lubricated bearing bush mainly include polymer, carbon graphite and special ceramics.
