Bearing Friction Calculation - Bearing Vibration Frequency

Bearing Friction. Rolling element bearings, such as ball bearings and roller bearings, are used in equipment primarily because they support the loads inherent to the machine’s function at a much lower friction level than any oil film bearing, such as bronze or Babbitt.This reduces the power required to drive the equipment, lowering the initial cost of the prime mover and the …
