Bearing Noise
The noise level is an important quality criteria of a ball bearing. It mainly depends on the following factors:
- precision of the geometric forms
- surface finish of the raceway and the balls
- cleanliness of the bearing
- type of lubricant
- type of cage
- rotational speed
The bearing noise levels are classified as follows at WIB:
Q0: Normal noise
Q6: Noise less than Q0
Q5: Noise less than Q6
Very intensive noise checks are carried out during the manufacturing process.
