Industry Applications

Bronze bearings are widely used across industries such as:

• Automotive: Engine components, suspension systems, and heavy-duty truck parts.
• Marine: Propeller shafts, pump bushings, and rudder bearings due to excellent corrosion resistance.
• Construction and Mining Equipment: Bearings used in loaders, excavators, and conveyor systems.
• Steel and Heavy Machinery: Applications involving high loads and continuous operations, such as rolling mills and presses.

C93200 (SAE 660) High Lead Tin Bronze

C93200, commonly known as SAE 660 bearing bronze, is widely used for bushings and bearings due to its excellent machinability, high strength, and wear resistance. It offers superior antifriction properties and does not suffer from dezincification, making it a reliable material for long-term performance in various applications.

C95400 Aluminum Bronze

Aluminum bronzes, such as C95400, are among the strongest copper-based alloys. Their aluminum content provides exceptional strength, enabling them to handle unit loads up to 50% higher than leaded tin bronzes like C93200. These alloys have excellent corrosion resistance, making them ideal for marine and high-temperature environments.

C86300 Manganese Bronze

C86300 manganese bronze combines high strength with excellent corrosion resistance. It performs well under high-speed and heavy-load conditions but requires hardened shafts and non-abrasive operating conditions. Manganese bronze is frequently used in heavy machinery, gears, and marine applications.

C92200, C92300, C92700 Leaded Tin Bronzes

Leaded tin bronzes, such as C92200, C92300, and C92700, contain lead for improved antifriction properties, though this reduces their overall strength. These alloys are known for their good conformability and ability to tolerate dirty operating environments, making them ideal for use in off-highway vehicles, earthmoving equipment, and other heavy industrial applications.

C95300, C95400, C95500 Aluminum Bronzes

These aluminum bronzes are heat-treatable, allowing for further enhancement of their strength. They are excellent used with hardened shafts, smooth surfaces, and reliable lubrication. Their high strength, excellent corrosion resistance, and performance in high-temperature environments make them suitable for demanding applications such as marine propellers and pump impellers.

Conclusion

The selection of the appropriate bearing bronze depends on factors such as load, speed, operating conditions, and required material properties. Engineers carefully evaluate these factors to ensure optimal performance in specific applications.
