ANALYSIS OF ENDURANCE LIFETIME FOR
SMALL BEARING BALLS
In order to determine the lifetime of bearing balls we need to proceed
to their fatigue test. The machine for fatigue testing has a special construction,
with several spaces for simultaneous tests. The contact between the ball to test
and the plate is plane. During the test, the machine’s number of revolutions and
the loading force are constant. An important parameter during testing is
represented by the environment conditions (with or without lubrication).
