What Are Bronze Bearings?
Bronze bearings are machine elements designed to reduce friction between moving parts. Made from copper alloys (primarily copper and tin), they often include additives like lead, aluminum, or zinc to enhance properties like lubricity, strength, and corrosion resistance. Their self-lubricating nature and ability to handle high loads make them ideal for demanding industrial environments.
How to Select the Right Bronze Bearing
Consider these factors:
- Load Capacity: High-load applications (e.g., crushers) require C95400HT.
- Speed: Low-speed, high-load systems benefit from leaded alloys like C93200.
- Environment: Marine/chemical industries need corrosion-resistant C93700 or C86300.
- Lubrication: Self-lubricating graphite-plugged bushings suit maintenance-free zones.
