They are more often used in low-speed, high-load and severe-duty industrial applications and machinery for iron and steel manufacturing, food processing, injection molding, automotive machines, earth moving machinery, pumps and other industries. One of the main advantages of copper bushing is their durability and resistance to wear. The copper alloy material used in the manufacturing process provides a high level of strength and resistance to corrosion, which allows them to withstand harsh operating conditions and last for long periods of time.
Two common bronze bushing materials and their uses include:
• Oilite: Oil impregnated bronze bushings formed using powder metallurgy. Applications depend on the type of oil used and may accommodate high and low speed machinery, high and low temperature machinery, and food-grade applications.
• Copper: Most often an alloy of bronze with tin, aluminum or silicon, these alloys have high corrosive resistance, making them ideal for marine applications.
Popular designs include bronze alloy graphite oil-less bushings, flanged bronze bushings and sintered bronze bushings.
