Noise life

For household appliances bearings, the bearing load is very small and the bearing life is very long.

However, after a certain period of operation, the bearing will also cause wear, increased vibration and noise, and deterioration of grease. Due to the strict requirements on the noise of the bearing of household appliances, when the noise of the bearing exceeds the allowable range, it is considered that the bearing can no longer be used.

The total time of low noise bearing operation is called bearing noise life.
