Bronze sleeve bushings or bronze bearings are hard and strong, as opposed to brass bushings, which are softer and more easily deform. Thus, bronze bushings have longer lifespans than brass bushing sleeves. They resist shock and impact, wear and corrosion.
They require an external lubricant, for example grease or oil, at installation and during operation to reduce friction and wear.
BRONZE BUSHING APPLICATIONS
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.
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.
