WEAR AND TEAR OF FATIGUE-TESTED
BEARING BALLS
The bearing balls with the 12.7 mm diameter equipping radial bearings
were tested for the fatigue endurance stress. The test was performed on a
specialised machine, which creates a constant force during testing, at a number
of revolutions that is also constant. By weighing and dimensional
measurements we find a mass loss after the fatigue test, and implicitly the
diameter became smaller due to wear and tear.
