Wrapped Bronze Bushing
Overview
Wrapped bronze bearings are manufactured from high-density copper alloy (CuSn8P) and can be customized with surface patterns such as diamond or hemispherical oil pockets, lubrication grooves, or uniformly distributed lubrication holes. After assembly and lubrication, these bearings facilitate rapid oil film formation during initial operation, reducing starting friction coefficient. They offer high density, exceptional load capacity, excellent wear resistance, and extended service life, serving as compact and cost-effective replacements for traditional cast bronze bushings. Widely used in agricultural, forestry, engineering, and construction machinery.

Key Applications
FAQs
1. Do the Bronze Bushings Need Grease?
Yes, bronze bushings require grease during installation and use.
When installing, you need to apply grease evenly to the outer surface of the bushing to reduce friction, facilitate press-in and avoid damage.
In operation, grease reduces wear, prevents corrosion, and improves sliding properties to extend bushing life.
2. What are the best Grease for Bronze Bushings?
There are the best oil for bronze bushings:
- Lithium Grease: Suitable for scenarios with operating temperatures ≤80℃, it has anti-aging properties and is the first choice for bronze bushings.
- Silicon Grease: better performance in high temperature environment (>80°C), can maintain stability and reduce volatilization.
- Graphite or White Lithium Grease: Commonly used in low to medium speed applications likeautomotive and industrial machinery, providing lubrication protection under high loads.
Note: Greases containing molybdenum disulfide (MoS2) may not be compatible with bronze materials and should be avoided.
3. What are the Bronze Bushings Used for?
- Industrial Machinery: gearboxes, pumps, bearing housings and other low-speed, high-load components.
- Automotive and Agricultural equipment: suspension systems, drive shafts, mechanical joints for tractors and harvesters.
- Marine & Food Processing: Marine components resistant to seawater corrosion, and food grade oiled bronze bushings.
- Aerospace: precision components for high temperature, high load environments such as landing gear and engine components.
