Zinc-based alloy bearings use zinc as their primary component, with other alloying elements (such as aluminum, copper, and magnesium) added to improve their mechanical properties and wear resistance. Commonly used zinc alloy grades include ZA8, ZA12, ZA27, ZA27-2, and ZA303.
 

Characteristics
Wear Resistance: Zinc-based alloy bearings exhibit excellent wear resistance, maintaining stable performance during prolonged operation and effectively extending equipment lifespan.
Corrosion Resistance: This material demonstrates superior corrosion resistance, maintaining a stable operating state even in humid or corrosive environments.
High-Temperature Stability: Under high-temperature conditions, zinc-based alloy bearings still maintain good mechanical properties, ensuring normal equipment operation.
Damping Characteristics: Zinc-based alloy bearings have high damping characteristics, which help reduce vibration and noise, improving the smooth operation of equipment.
Low Density and Light Weight: Zinc alloys have a low density, resulting in relatively lightweight bearings, making installation and maintenance easier.
 

Applications
Zinc-based alloy bearings are widely used in various mechanical equipment, such as automobiles, construction machinery, ships, chemical equipment, and marine equipment. In high-load, high-speed operating environments, they provide stable support and lubrication, ensuring smooth equipment operation. Due to their excellent performance, zinc-based alloy bearings have gradually replaced some babbitt and bronze bearings, becoming an indispensable key component in modern industry.
 

Importance
As a key component in mechanical equipment, the performance of zinc-based alloy bearings directly affects the overall operating efficiency and lifespan of the equipment. High-quality zinc-based alloy bearings can significantly improve equipment stability and reliability, reduce maintenance costs, and increase production efficiency.
