Rolling bearing
Thread Content
What is the clearance between the bearings and the bearing caps of a centrifugal pump? For example, for 6307 bearings
Check the manual, the bearing manual, the mechanical manual
What structural type of centrifugal pump? Front bearing or rear bearing? High-temperature pump or room temperature?

For deep groove ball bearings under normal temperature conditions, a value of 0.2–0.3 can be used for the free end, while 0.1–0.2 can be used for the fixed end; these values depend on the manufacturing precision of the company and the precision of the bearing itself
The bearing clearance at the impeller end generally does not need to be considered! If both ends are deep groove ball bearings, generally two sets of bearings together with the shaft are pressed into the bearing housing. The bearing at the front end does not have any axial positioning relative to the coupling within the housing; since the shaft is considered as a single unit, it is sufficient to measure only the bearing clearance at the coupling end! If the impeller end bearing is a cylindrical roller bearing, all that needs to be considered is that the front bearing cover is not pressed shut, so as to prevent the seal gasket from failing! Can’t learn well! I’ll just watch it!
There are relevant regulations in the maintenance procedure manual; I remember it’s around 10–15 degrees for the bearing caps and bearing clearance.
