What are the materials, advantages, disadvantages and applications of graphite oil groove bronze bushings?

The graphite oil groove bronze sleeve is a composite lubricating copper sleeve that combines graphite and oil groove designs. It has both self-lubricating performance and the advantages of traditional lubricants.

Material：

Graphite embedding: Embed graphite blocks or graphite particles on the inner surface of the copper sleeve to form evenly distributed graphite lubrication points.

Oil groove design: An oil groove is designed on the inner surface of the copper sleeve to store and transport lubricating oil, so that the lubricating oil and graphite can work together on the friction surface.

Copper matrix: Generally, high-strength, wear-resistant copper alloys (such as tin bronze, aluminum bronze, etc.) are used as the matrix material to provide good mechanical properties.

Graphite insert: The embedded graphite material has excellent self-lubricating properties and can maintain stable lubrication effect under high temperature and high load.

advantage:

Dual lubrication: combines the advantages of graphite self-lubrication and oil tank lubrication to provide longer and more stable lubrication.

High temperature resistance: Graphite can still maintain good lubrication properties at high temperatures and is suitable for high temperature working conditions.

Excellent friction reducing performance: graphite and lubricating oil work together to significantly reduce the friction coefficient and reduce wear.

Low maintenance costs: Graphite provides a self-lubricating effect, reducing dependence on external lubricants, reducing maintenance frequency and costs.

disadvantage：

High manufacturing costs: The composite design and manufacturing process are complex and the cost is relatively high.

Limited scope of application: It is mainly suitable for specific working conditions such as high temperature, high load, low speed, etc., and is not suitable for all application environments.

application：

Reduce friction: Provide stable lubrication effect, significantly reduce friction coefficient and wear.

Extend service life: reduce wear and improve the service life and reliability of mechanical parts.

Improve performance: maintain good lubrication effect under high temperature and high load conditions, and improve equipment operating performance.

High temperature working conditions: suitable for bearings and sliding parts in high temperature environments such as metallurgy and glass manufacturing.

Heavy-duty equipment: mechanical components used in high-load, low-speed operation such as engineering machinery and mining equipment.

Equipment that is difficult to maintain: Suitable for use in equipment that is difficult to maintain or lubricate regularly, such as marine equipment and mechanical equipment in remote areas.

Chemical equipment: Used for corrosion-resistant and high-temperature-resistant chemical equipment components to provide stable lubrication and corrosion resistance.

The graphite oil groove bronze sleeve combines graphite and oil groove design to provide excellent lubrication performance and high temperature resistance. It performs well under specific working conditions and is an ideal choice in high temperature and high load environments.
