Bronze bushing is a special type of wrapped bronze bearing with oil holes. It is a hollow cylindrical component, typically split into two parts, and may have one, two, or even no flange. These bushings are used for axis elongation and are designed to withstand friction forces during rotation. They are widely applied in various machinery, including lightweight, heavy, and super-heavy equipment.
Bimetal bushing is made by backing low carbon steel with CuPb10Sn10 or CuSn6Zn6Pb3 bronze powder through sintering. This type of bushing offers the highest load capacity among bimetal bearings and is commonly used in applications such as balance suspensions for heavy-duty trucks, track rollers for bulldozers, and automotive chassis components.
This is a high-load and low-speed bushing with broad application possibilities.
