Centrifugal pump bearing housing
Thread Content
Let’s all discuss the consequences of the bearing housing running on its outer circumference, as well as what the symptoms are when this occurs
When the bearing housing moves along its outer circumference, it means the bearing is moving along that outer surface; the reason for this is that the bearing seat isn’t pressed firmly enough. This usually occurs when the bearing housing is manufactured using the base hole system (with too small a lower tolerance), and the issue can be resolved by using copper shims. When the bearing runs on its outer circumference, noise, vibration, current, and so on all increase. It should generally be dealt with promptly.
If the outer ring of the bearing wears out, higher temperatures and greater vibration in the bearing housing will be observed during operation. Upon disassembly, the oil will be found to be blackened, and grooves will appear in the area where the bearing is mounted; if this is not addressed promptly, the pump will soon get damaged.

It may also rub against the bearing housing.
