Machine equipment bearing shell

We specialize in producing various copper lead alloy, aluminum tin alloy, Babbitt alloy materials for bearing shells, shaft sleeves, and thrust plates. In addition to producing products with specifications for the main engine, we also design and produce various non-standard bearing shells, shaft sleeves, thrust plates, and refurbish and produce various large marine main engine bearing shells for customers. We will provide our customers with excellent product quality and reasonable prices in a timely manner. Welcome to contact and negotiate.

A bearing shell is the part of a sliding bearing that comes into contact with the journal. It is a semi cylindrical surface in the shape of a tile, very smooth, and is generally made of wear-resistant materials such as bronze and anti friction alloys. In special cases, it can be made of wood, engineering plastics, or rubber.

There are two types of bushings: integral and split. Integral bushings are usually referred to as bushings. There are two types of integral bearing shells: those without oil grooves and those with oil grooves. The bearing shell and journal adopt a clearance fit and generally do not rotate with the shaft.

When sliding bearings work, a very thin oil film is required between the bearing shell and the shaft for lubrication. If there is direct friction between the bearing and the shaft due to poor lubrication, the friction will generate high temperatures. Although the bearing is made of a special high-temperature resistant alloy material, the high temperature generated by direct friction is still enough to burn it out. The bearing shell may also burn out due to factors such as excessive load, high temperature, impurities in the lubricating oil, or abnormal viscosity. After burning the tile, the sliding bearing was damaged.
