Fatigue life
Rolling operation of the process, under a certain load, even the static load, but the balls and raceway purposes, the stress is the cycle of the material will occur so that the bearing rolling fatigue reaches the life. Phenomenon rolling surface materials like fish scales suddenly fell off, a phenomenon known as fatigue spalling (Flaking).abec 9 bearings
Noise life
Bearings imported bearings to withstand the load is very small household appliances, long bearing life. But the bearing running for some time after, will wear, vibration and noise increases, grease deterioration. When the bearing noise outside the allowable range, due to the strict requirements of the appliance bearing noise, that can no longer continue to use the bearing. Total time bearing low noise operation called bearing noise life.
Lubrication life
Household appliances Bearings are usually maintenance-free greased sealed bearings. Although the bearing lubrication requires only a trace amount of the lubricant, but in operation after a long time due to the deterioration of the grease leakage, bearing lubrication bad, so that the bearing failure. The total time of operation in the the bearing good lubrication state called the bearing life.bearing company
For light-load bearing, the imported bearing noise life and lubrication life shorter than bearing fatigue life. Such as household appliances bearing the correct bearing selection and installation, and fully meet the matching requirements of the life of the host.
