NSK bearing life and failure

Bearing life and failure: Life Category: fatigue life and wear life, the failure life, life.
Fatigue life: the bearing material moving parts reaches the limit, caused by the NSK bearings failure before the cumulative time.
1) Rated load: life expectancy of 10,000 rpm, the bearings can withstand the load.
2) equivalent dynamic load: NSK Bearings and actual load operating conditions to determine the dynamic load the converted assumed load.
Wear life: bearings due to normal wear, clearance increases to the total working hours before the specified limits. Today NSK Bearings industrial level should wear life, but in fact the traction motor otherwise.
3, Fault life: Bearing failure, loss of ability to work before the cumulative working time.
Life: life refers to the formulation of the three, in theory, it refers to the fatigue life of the bearing, NSK Bearings wear life under normal use conditions, the condition is not normal, no manufacturing defects, on behalf of the fault life.
