What is the sound of the bearing in normal operation?

date:2022-03-30 Views:1799

1. If the bearing is in good continuous rotation state, it will make a low whine or buzzing sound. If there is a sharp hiss, squeak and other irregular sounds, it often indicates that the bearing is in poor continuous rotation condition. Sharp squeaking noises may be caused by improper lubrication. Improper bearing clearance can also cause metallic sound.

2. The dent on the track of the bearing outer ring will cause vibration and make a smooth and crisp sound.

3. If there is intermittent noise, it means that the rolling parts may be damaged. This sound occurs when the damaged surface is rolled out. If there are pollutants in the bearing, it will often cause a hissing sound. Serious bearing damage can produce irregular and loud noise.

4. If the knocking scar caused during installation will also produce noise, the noise will vary with the bearing speed.
