Operating under slide bearingcertain ideal conditions, angular contact ball bearings can get more than traditional computing life: as under light load conditions; or "rolling surface contaminants (track and rolling elements) are effectively separated by a lubricant film and restrictions

certain ideal conditions, angular contact ball bearings can be obtained over the life of the traditional calculation: as in the case of light loadPlastic bearing; or "contaminants are efficiently separated by a lubricant film rolling surface (track and rolling elements) and restrictions reduce the rolling surface damage under the surface, "such ideal conditions。 But in fact, there is the reality of various factors, the impact of angular contact ball bearing life, a simple analysis is as follows:

 

(1) poor lubrication

 

Angular contact ball bearings used oil (or grease) has a certain temperature, it will deteriorate when the temperature is too high, and thus loss of lubrication, the angular contact ball bearings due to high temperature burning。 In addition, the oil (or grease) poor texture or run their own refueling (fat) is not timely, angular contact ball bearings can also cause elevated temperatures or produce a different sound。

 

(2) rotor imbalance

 

Typically, the rotor dynamic operation of the equipment should be carried out prior to assembly, static equilibrium, so angular contact ball bearings are not the problem。 However, some of the rotor during operation due to corrosion or wear of the medium solid impurities, or there is an axial bending, centrifugal force will result in imbalance, so that angular contact ball bearing heating, vibration, roller severe wear until the destruction 。

 

(3) Check the replacement is not timely

 

Angular contact ball bearings during operation, periodic inspection in accordance with regulations, if fever, abnormal sound, vibration, etc。, to stop in time to find the cause and eliminate the fault, angular contact ball bearings found severe fatigue spalling, oxidation corrosion, wear and tear dents, cracks, hardness reduced to HRC
