The bearing type is 6208, and the outer ring of the bearing is fixed to the bearing seat (HT200), but there is no rotation, and the inner ring rotates with the shaft. It's not ideal to look up some information. Forget master advice!Want to find bearings and shafts, bearing seat tolerances and coordination, the shaft diameter of 40, the bearing seat of the inner diameter of 80, bearing inner ring with the shaft rotation, the outer ring relative to the bearing seat at rest
Let the bearing outer ring than the bearing seat diameter a little bit, forming interference fit
