Bronze bushings are mechanical components made from various copper alloys, primarily used to reduce friction and improve equipment efficiency and lifespan. They are categorized into various types, including machine copper rollers, copper bearings, and further classified based on lubrication methods: self-lubricating bronze bushings, oil-free bronze bushings, oil-requiring bronze bushings, and graphite bronze bushings.

Materials and Manufacturing
Bronze bushings are typically made from electrolytic copper, combined with various trace metal elements, and processed through high-temperature sintering and pressure centrifugal casting. This manufacturing process results in bushings with high hardness, excellent wear resistance, and superior casting and machining properties.

Characteristics and Advantages
1. High Hardness and Wear Resistance: Bronze bushings, after special processing, possess high hardness and wear resistance, capable of withstanding significant mechanical loads and frictional wear.
2. Excellent Lubrication Performance: Even without lubricants or with water-based lubricants, bronze bushings maintain good slidability and self-lubricating properties, reducing friction and wear, and improving equipment efficiency.
3. Corrosion Resistance: Bronze bushings exhibit excellent corrosion resistance to air, freshwater, and dilute sulfuric acid, maintaining stable performance in harsh environments.
4. Easy Machining and Connection: Bronze bushings are easy to machine and connect, saving materials and overall costs while ensuring stable and reliable installation.

Application Areas
Bronze bushings are widely used in various light, large, and heavy machinery, as well as electrical engineering, automotive industry, metallurgy, chemical industry, and construction engineering. Specifically:

1. Mechanical Engineering: Used as bearing components in machinery to reduce friction and wear.
2. Electrical Engineering: Used as insulating sleeves for wires and cables, protecting them from external environmental influences.
3. Automotive Industry: Used in critical components such as crankshafts and connecting rods in automobile engines, improving engine performance and lifespan.
4. Metallurgical Industry: Used in furnaces and containers in metallurgical equipment, aiding in the control of heating and cooling processes.
5. Chemical Industry: Used in sealing components in chemical equipment, resisting corrosion and high temperatures.
6. Construction Engineering: Used in building water heating systems, such as sealing sleeves in pipe connections.
 

Maintenance and Care
To ensure the normal operation and extend the lifespan of bronze bushings, regular maintenance and care are necessary. This includes checking for wear and tear, timely replacement of severely worn bushings, and maintaining the cleanliness of the lubrication system and sufficient lubricant.
