Noise factors occur in bearings

Bearings are the main running parts of the majority of mechanical equipment. During use, their own performance effects will directly affect the use of mechanical equipment. Therefore, many people will hear some noise during the use of bearings, which is very It may be the result of our daily lack of careful maintenance. Of course, there are various reasons for the occurrence of bearing noise.

1. Impurities such as sand or carbon particles are mixed into the bearing to act as abrasives

2. The bearing is mixed with water, acid or paint and other dirt, which will play a role in corrosion;

3. The clearance of the bearing is too small (the fit is not properly selected);

4. Wrong selection of lubricating oil or grease;

5. Insufficient lubrication (oil level is too low, oil or grease leaks through the seal);

6. The bearing is flattened by the seat hole (the roundness of the seat hole is not good, or the seat hole is twisted and not straight);

7. The pad iron on the bottom surface of the bearing seat is uneven (leading to deformation of the seat hole and even cracks in the bearing seat);

8. There are sundries in the bearing seat hole (residual chips, dust particles, etc.);

9. The sealing ring is eccentric (touching adjacent parts and causing friction);

10. The bearing is subject to additional load (the bearing is subject to axial tightness, or there are two fixed end bearings on one shaft).
