Series bi-metal bushings are a type of plain bearing that consists of two different metals, usually steel and bronze, that are bonded together. The steel backing provides strength and rigidity, while the bronze layer provides wear resistance and self-lubrication properties.
The bi-metal construction of these bushings allows for a combination of strength and wear resistance, making them ideal for high-load and high-impact applications. The steel backing provides excellent load-carrying capacity, while the bronze layer provides excellent wear resistance and self-lubrication properties.
Series bi-metal bushings are commonly used in applications such as automotive engines, construction equipment, and industrial machinery. They offer several advantages, including reduced friction and wear, longer service life, and improved performance in harsh and dirty environments.
However,
series bi-metal bushings can be more expensive than other types of bearings due to their advanced materials and manufacturing process. They can also be prone to galvanic corrosion, which can occur when two dissimilar metals are in contact with the presence of an electrolyte, such as water or moisture. Proper maintenance and inspection are necessary to prevent corrosion and ensure the optimal performance of these bushings.
