Copper alloy bushing self-lubricating solid graphite
A copper alloy bushing with a self-lubricating feature and solid graphite is a type of bearing that incorporates both copper and graphite materials to enhance its performance. The copper alloy provides strength and durability, while the solid graphite acts as a lubricant, reducing friction and wear.
Experience
This combination offers several advantages. The copper alloy base provides excellent mechanical properties, such as high load-bearing capacity and resistance to corrosion. It also allows for precise machining and fitting within various applications.
Bronze Bearing Solutions
The addition of solid graphite to the bushing creates a self-lubricating effect. Graphite has natural lubricating properties, which means that as the bushing operates, it releases small amounts of graphite particles that reduce friction between the bearing surfaces.

Self-lubricating bearings copper alloy
Copper alloy self-lubricating bearings with a groove type design provide significant advantages for a variety of applications. Self-Lubricating Feature
Self-lubricating bearings contain lubricant within the bearing material itself. This could be due to the material properties of the copper alloy, or because of lubricant-filled plugs or grooves in the bearing. The self-lubricating feature means that these bearings don’t require additional lubrication during operation, which simplifies maintenance and can significantly extend the bearing life.

Groove Type Design
In groove type bearings, a pattern of grooves is etched or machined into the bearing surface. These grooves serve a critical purpose: they hold and distribute the lubricant across the bearing surface. This optimizes lubrication, reduces friction, and enhances the bearing’s performance.

Cast bronze bearings are a specific type of copper alloy bushing. Here’s a general overview of their material composition and properties:
Material Composition:
Cast bronze bearings are primarily made of bronze, which is an alloy consisting largely of copper, usually combined with tin. However, other elements such as aluminum, lead, or nickel can also be added to create bronze alloys with specific properties.
For example, the addition of aluminum (aluminum bronze) can enhance strength and corrosion resistance, whereas the addition of lead can improve wear resistance and machinability.
Material Properties:
- High Load Capacity: Cast bronze bearings are known for their high load capacity. They can withstand heavy loads and high pressure without deforming or failing.
- Excellent Wear Resistance: The alloy composition of these bearings provides superior wear resistance, making them suitable for applications where durability is crucial.
- Low Friction: Cast bronze bearings have a low coefficient of friction, which allows for smooth operation and reduces wear and tear on machinery parts.
- Corrosion Resistance: Bronze is inherently resistant to corrosion, including in marine environments. Specific types of bronze, like aluminum bronze, offer even greater corrosion resistance.
- Heat Resistance: These bearings can withstand a wide range of temperatures without losing their structural integrity or performance.
- Machinability: Bronze bearings are relatively easy to machine, which allows for a high degree of customization in terms of size, shape, and design.
It’s worth noting that the exact composition and properties can vary depending on the specific type of bronze alloy used and the manufacturing process. Always ensure that the type of bronze used is suitable for the specific application in which the bearing will be used.
