key aspects of RG7 bronze bushings:

  1. Composition: RG7 bronze typically contains a high percentage of copper, with tin and other elements like zinc, lead, and phosphorus. The specific composition can vary, but the primary constituents remain copper and tin.
  2. Properties: This alloy is known for its high wear resistance, good sliding properties, and excellent resistance to corrosion. The presence of lead in the alloy improves its machinability and wear resistance, while the tin enhances the mechanical properties and corrosion resistance.
  3. Self-Lubricating: RG7 bronze often has self-lubricating properties, meaning it can operate with minimal additional lubrication. This is particularly beneficial in environments where regular maintenance and lubrication are difficult.
  4. Applications: Due to its durability and resistance to wear and corrosion, RG7 bronze bushings are used in various industrial applications. They are particularly suited for heavy load applications and can be found in machinery in the steel, marine, agricultural, and earth-moving industries.
  5. Customization: RG7 bronze bushings can be custom-sized to fit specific requirements, making them versatile for different machinery and equipment.
  6. High-Temperature Performance: These bushings can perform well in high-temperature environments, making them suitable for applications where heat resistance is crucial.

RG7 bronze bushings are a reliable choice for applications requiring durable, corrosion-resistant, and self-lubricating bearings, especially in harsh industrial environments.
