Copper Bushing Bearing Factory

Our embedded self-lubricating copper sleeve bushings represent a new generation of anti-pressure solid lubrication composite materials. These bushings feature a copper sleeve as the metal matrix, with graphite embedded in an orderly arrangement on the friction surface, providing superior self-lubricating properties.

Copper bushing vs. self-lubricating bearings vs. sinter bushings

copper bushings require external lubrication, self-lubricating bearings contain solid lubricants, and sinter bushings are impregnated with oil for lubrication. Self-lubricating and sinter bushings are preferred when external lubrication is difficult or undesirable.

What Is Copper Bushing?

Copper sleeves, also known as copper bushings, are divided into many types, including machine copper rollers, copper bearings, etc. It is used in various light industries, large and heavy machinery, and is an important component of machinery.

Copper bushings are cylindrical bearings made from copper or copper alloys, which are used to reduce friction between moving parts in machinery. They are typically installed in housings with a press fit and are designed to accommodate rotational or oscillating movements. The primary function of a copper bushing is to act as a bearing surface that supports loads while facilitating smooth and efficient operation of mechanical components.


Key Features of Copper Bushings

Key Features of Copper Bushings:

  • Material Composition: Made from high-quality copper or copper alloys, which offer excellent thermal and electrical conductivity, as well as corrosion resistance.
  • Load Bearing: Capable of withstanding both radial and axial loads, ensuring the stability and longevity of mechanical assemblies.
  • Low Friction: The natural lubricity of copper and its alloys reduces friction, which in turn minimizes wear and energy consumption.
  • Wear Resistance: Copper bushings exhibit good resistance to wear, which helps to maintain the integrity of the mechanical system over time.

Materials and Properties of Copper Bushings

Copper bushings are engineered to meet the demands of various applications, and their composition and properties are key to their widespread use.

Composition of Copper Bushings

Copper bushings can be made from pure copper or a variety of copper alloys. The choice of material depends on the specific requirements of the application, including:

  • Pure Copper: Known for its excellent electrical and thermal conductivity, high ductility, and resistance to corrosion.
  • Phosphor Bronze: An alloy with tin as the main alloying element, offering high strength, good bearing properties, and resistance to wear.
  • Brass: A copper-zinc alloy that is strong, corrosion-resistant, and has good mechanical properties.
  • Copper-Lead: Used for its excellent machinability and high conformability, ideal for applications with heavy loads.

Physical and Mechanical Properties

The physical and mechanical properties of copper bushings are what make them suitable for a wide range of applications:

  • Thermal Conductivity: Copper has high thermal conductivity, which allows for efficient heat dissipation in mechanical systems.
  • Electrical Conductivity: Pure copper bushings can be used in applications where electrical conductivity is required.
  • Corrosion Resistance: Copper alloys are resistant to many forms of corrosion, making them durable in various environments.
  • Strength and Hardness: Copper bushings can be heat-treated to achieve the desired level of hardness and strength.
  • Wear Resistance: The material is known for its ability to withstand wear, reducing the need for frequent replacement.
  • Low Coefficient of Friction: Copper bushings have a naturally low coefficient of friction, which helps in reducing energy loss due to friction.
Advantages Over Other Materials

Copper bushings offer several advantages over other materials used for bushing applications:

  1. Better Lubricity: Copper and its alloys have a natural lubricity that reduces the need for additional lubrication.
  2. Compatibility with Lubricants: They work well with a variety of lubricants, enhancing performance in different environments.
  3. Recyclability: Copper is highly recyclable, contributing to a sustainable manufacturing process.
  4. Cost-Effectiveness: While copper can be more expensive than some other materials, its longevity and performance can make it a cost-effective choice in the long run.
  5. Versatility: Copper bushings can be tailored to various applications through different alloy compositions and heat treatments.
  6. Non-Ferrous Nature: Being non-ferrous, copper bushings do not contribute to galvanic corrosion when paired with steel components.
  7. Biocompatibility: In certain applications, such as medical devices, copper’s biocompatibility is a significant advantage.

In conclusion, the composition and properties of copper bushings make them a reliable and efficient choice for a variety of mechanical applications. Their advantages over other materials in terms of performance, durability, and environmental impact contribute to their continued use and development in the engineering and manufacturing industries.

Copper Bushes + Graphite Plugged

Graphite copper bushes, the surface consists of a metal substrate and a molded solid lubricant with unique self-lubricating properties embedded in the holes or grooves of the substrate. The graphite-plugged copper bushing combines the respective advantages of metal and specially formulated lubricating material, which can complement each other, i.e., it has the high load-bearing capacity of metal and the lubricating performance of wear-reducing material, breaking through the limitation of general bushings relying on oil film lubrication.

Self-lubricating Graphite Plugged Copper Bearing

Copper pipe with graphite makes solid lubrication and shaft friction through friction heat in the process of use, forming excellent conditions of oil and powder coexistence lubrication, which not only protects the shaft from wear but also makes the solid lubrication characteristics eternal. However, its hardness is twice as high as general bushings, and its wear resistance is also twice as high.

Varieties of Copper Bushings

Copper bushings come in a variety of types, each designed to fulfill particular requirements:

  1. Plain Bushings: These are the simplest type, consisting of a solid piece of copper alloy that acts as a bearing surface.
  2. Flanged Bushings: Featuring an external flange, these bushings provide additional support and positioning stability.
  3. Split Bushings: Designed to be easily fitted into housings without the need for dismantling the surrounding components.
  4. Self-Lubricating Bushings: Incorporate materials such as graphite or molybdenum disulfide for enhanced lubricity.
  5. Oil-Immersed Bushings: These bushings are designed to be used with a continuous supply of lubricating oil.
  6. Thrust Bushings: Specifically designed to handle axial or thrust loads.
  7. Spherical Bushings: Provide flexibility in multiple directions, often used in applications requiring angular misalignment compensation.

Our copper bearing products include graphite copper bushing, white graphite copper bearing, flanged copper sleeve bushing, automotive mold guide bushing, double flange shaft tile, mold guide bushing, square flange copper bushing, self-lubricating guide plate, thrust washer, joint bearing, graphite steel bushing, and non-standard customized copper bushing.
