The fatigue life of rolling bearings during operation, under a certain load, even if it is a static load, but the balls and raceways, the stress cycle of the materials will be rolli ng fatigue so that the bearings to achieve life. Phenomenon as part of a rolling surface material like fish scales suddenly fell off, a phenomenon known as fatigue spalling (Flaking). Noise life of household appliances bearing, bearing load is very small, very long bearing life. Bearing operation for some time, will produce wear, vibration, increased noise, grease degradation. Demanding home appliance bearing noise, bearing noise outside the allowable range, the bearings can no longer continue to use. The total time of bearing low-noise operation called bearing noise life.double row ball bearing
Household appliances Bearings are usually maintenance-free greased sealed bearings. Bearing lubrication only need a small amount of lubricant, but running a long time due to deterioration and leakage of grease, poor bearing lubrication, so that the bearing failure. The total operation time in the st ate of good bearing lubrication is called the bearing life.NTN bearig
For light-load bearing, bearing noise of life and lubrication life is shorter than the bearing fatigue life. Such as household appliances bearing, bearing selection and installation is correct, fully meet the needs of the life of the host to match requirements.double row angular bearing
