Ball-Bearing Durability Evaluation Test

| Ball-Bearing Durability Evaluation Test

Evaluation of bearings operating in a water-lubricated environment by applying a load in the axial direction

Description

  • Bearing wear test
    • Fabrication of tester to simulate axial load and water lubricated environment
    • Wear test with a maximum of 670,000 rotations
    Bearing drop impact test
    • Impact test to simulate an emergency while using the ball bearing

Records

  • High load water lubrication test
    Torque change during an experiment
