What are the sintered bronze bushings?

There are many types of sintered bronze bushings in the machinery industry, which are mainly classified according to their composition, manufacturing process and application environment. The following are several common sintered bronze bushings:

Standard sintered bronze bushings:

Material: Mainly made of copper and tin powder.

Application: Commonly used in light-load and medium-load bearing parts, widely used in motors, home appliances, office equipment, etc.

Oil-containing sintered bronze bushings:

Material: Lubricants such as graphite or polytetrafluoroethylene (PTFE) are added to copper-based powder.

Application: Suitable for occasions that are not easy to maintain and have self-lubricating properties, such as fans, power tools, household appliances, etc.

High-strength sintered bronze bushings:

Material: Usually contains a higher proportion of copper and other metal elements such as iron, nickel, etc. to improve mechanical strength.

Application: Used in high-load and high-speed occasions, such as the automotive industry, construction machinery, heavy equipment, etc.

High-wear-resistant sintered bronze bushings:

Material: Add wear-resistant materials such as silicon carbide, aluminum oxide, etc. to improve wear resistance.

Application: Suitable for high wear environments, such as mining equipment, agricultural machinery, textile machinery, etc.

High temperature resistant sintered bronze sleeve:

Material: Add high temperature resistant metal or non-metallic materials to improve stability in high temperature environment.

Application: Suitable for high temperature environment, such as aerospace, metallurgical equipment, etc.

Composite material sintered bronze sleeve:

Material: Use composite powder of copper and other metal or non-metallic materials.

Application: Depending on the composite material, the application field is wide, such as mechanical equipment requiring specific performance.

Porous sintered copper sleeve: With high porosity, it can store more lubricating oil, further enhance its self-lubricating properties, and is suitable for high speed and heavy load mechanical equipment.

These sintered copper sleeves have a wide range of applications in the machinery industry. Choosing the appropriate type of sintered copper sleeve can significantly improve the operating performance and service life of the equipment.
