Product Structure and Features
Base Material: Typically rolled from high-tin bronze strip (such as CuSn8P), providing excellent mechanical properties and wear resistance.
Lubrication: Solid graphite lubricant is embedded in the bearing structure, creating a self-lubricating system that can operate in oil-free or low-oil conditions.
Typical Manufacturing: Manufactured through rolling, shaping, and impregnation processes, these bearings may feature thrust flanges or oil grooves and holes.
Performance Advantages
Self-lubricating: Graphite lubricant forms a transfer film during friction, reducing the coefficient of friction.
Wear Resistance: The bronze matrix + graphite composite structure provides excellent wear resistance and longevity.
Wide Operating Temperature Range: Generally operates in environments ranging from -40°C to +200°C.
Corrosion Resistance: Bronze has a certain degree of corrosion resistance.
Application Feature
Automotive parts: Brake caliper guide pins, chassis joints
Industrial machinery: Injection molding machine template slides, conveyor line support bases
Construction machinery: Excavator pin bushings, crane spherical plain bearings
Agricultural equipment: Tractor suspension linkages, harvester rotating parts
