500# Solid-Lubricant-Inlaid Bearing Bushing



Structure Characteristics:

     This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion. Solid lubricants within a bronze combines the strength of the bronze with the wear resistance and low friction. The application including automotive products line, water engineering, dam gate, plastic industries etc. Different bronze alloy type can be available according to the work condition.

Material Properties:

  1. Allows maintenance-free and long-life operation;

  2. Suitable for high static and dynamic loads;

  3. With low and smoothly coefficient of friction and without stick-slip effects;

  4. Suitable for dirty, corrosion, impact load and edge loading;

  5. Can be used over a large temperature range;

  6. The base material provided a good shock absorbing capacity;

  7. Suitable for reciprocating , rotating and oscillating movement with start frequency and difficulty to form oil film occasions;

  8. With low wear rate and long life service.
