Rolling failure modes are the following

(1) fatigue pitting the rolling elements and raceway rings in contact stress in the pulsation cycle under stress or when the number of stress cycles after more than a certain value, there will be a contact surface contact fatigue pitting. Pitting the bearing vibration and noise during operation, rotary precision and reduce the operating temperature increases, the bearing loss of normal working capacity. Pitting contact fatigue is the main failure mode of rolling bearings.
(2) plastic deformation under excessive static load or impact load effect, ring raceway or rolling elements may be plastically deformed raceway pits or rolling elements appear to be compressed, so that running accuracy decreased, vibrate and noise, leading to bearing not work properly.
(3) wear under poor lubrication, sealing unreliable and dusty conditions, the rolling elements or raceway rings prone to abrasive wear, there will be hot glued wear at high speed, resulting in rolling element bearings will overheat tempering.
Further, since the rolling bearing fit, installation, removal and use of improper maintenance, can also cause rupture element bearings and other forms of failure, we should also take appropriate measures to prevent it.
