Description

In the challenging worlds of mining, construction, and drilling, equipment reliability is paramount. Our Wrapped Cast Bucket Bushings and Drill Flange Copper Graphite Bronze Bushings are engineered to deliver exceptional performance in the harshest conditions. Combining the robustness of cast iron with the self-lubricating properties of copper-graphite and the corrosion resistance of bronze, these bushings are the ideal solution for high-load, abrasive, and high-temperature applications.

Key Features & Benefits

  • Exceptional Load Capacity: The cast iron base can handle loads exceeding 200 MPa, making it suitable for the most demanding applications.
  • Self-Lubricating Performance: The copper-graphite overlay reduces friction and wear, eliminating the need for frequent lubrication and reducing downtime.
  • Corrosion Resistance: The bronze wrapping protects against corrosion, extending the service life of the bushings in harsh environments.
  • High-Temperature Stability: Operates effectively in temperatures ranging from -40°C to 300°C, ensuring reliability in extreme conditions.
  • Precision Engineering: Manufactured to tight tolerances (±0.02mm) for a perfect fit and optimal performance.
    Customizable Design: Available in a wide range of sizes and configurations, including flanged designs for secure mounting.

Applications

  • Mining Equipment: Excavator bucket pins, drill rig flanges, and crusher bearings.
  • Construction Machinery: Bulldozer track rollers, loader arm bushings, and hydraulic system components.
  • Oil & Gas Drilling: Rotary table bearings, drill string couplings, and downhole tool components.
