SAE 65 bronze bushings properties, applications, and key benefits:

SAE 65 bronze bushings, also known as C90700 tin bronze bearings, offer several distinct advantages compared to other types of bronze bushings.

While different bronze alloys have their specific strengths, SAE 65 bronze bushings stand out for their combination of high strength, excellent corrosion resistance, and superior wear resistance. These properties make them particularly suitable for heavy-duty and marine applications where other bronze bushings might not perform as well. However, the choice of bushing material should always be based on the specific requirements of the application, considering factors such as load, speed, environment, and maintenance needs.

SAE 65 bronze bearings with graphite plugs

SAE 65 bronze bearings with graphite plugs offer a robust solution for high-load, low-speed applications where traditional lubrication methods are impractical. Their self-lubricating properties, combined with the mechanical strength of bronze, make them a reliable choice for demanding industrial environments.

Graphite Plugged Bearings Construction and Functionality

 

Graphite plugged bearings are constructed by embedding graphite plugs into the bronze material. The graphite acts as a solid lubricant, providing continuous lubrication without the need for external lubricants. This is particularly beneficial in applications where regular maintenance is challenging or impractical.

Graphite Plugged Bearings

These bearings are ideal for applications requiring durability, reduced friction, and minimal maintenance.

Graphite plugged bearings made from SAE 65 bronze, also known as C90700 tin bronze, combine the mechanical strength of bronze with the self-lubricating properties of graphite.

SAE 65 Bronze (C90700) Characteristics

SAE 65 bronze, or C90700 tin bronze, is a high-tin bronze alloy known for its excellent wear resistance, high strength, and good corrosion resistance. It typically contains:

  • Copper (Cu): 88.00 – 90.00%
  • Tin (Sn): 10.00 – 12.00%
  • Lead (Pb): 0.50% max
  • Zinc (Zn): 0.50% max

This material is employed across a range of applications, with common uses including gears and bearing bushings.

C90700 (SAE 65) Tin Bronze is a durable and robust alloy known for its excellent corrosion resistance, particularly in seawater, making it highly effective for wear and fatigue applications.

Advantages:

  1. Self-Lubricating: Graphite plugs provide a constant source of lubrication, reducing friction and wear.
  2. High Load Capacity: Suitable for heavy load applications due to the strength of the bronze and the lubricating properties of graphite.
  3. Corrosion Resistance: Effective in humid or mildly corrosive environments.
  4. Wide Temperature Range: Can operate effectively across a broad range of temperatures.
  5. Maintenance-Free: Reduces the need for regular maintenance and lubrication, recognized to cost savings.
