Installation of four row tapered roller bearings (installation of roller bearings):
1、 The fit between the inner ring of the four row tapered roller bearing and the roller neck is generally with clearance. When installing, first install the bearing into the bearing box, and then install the bearing box into the journal.
2、 The outer ring of the four row tapered roller bearing and the bearing housing hole also use a dynamic fit. First, install the outer ring A into the bearing housing. When leaving the factory, the outer ring, inner ring, and inner and outer spacer rings are printed with the symbol 'HotTag'. During installation, they must be installed in the bearing box in the order of the character symbols. It cannot be interchanged arbitrarily to prevent changes in bearing clearance.
3、 After all the parts are installed in the bearing box, tighten the inner ring and inner spacer ring, and the outer ring and outer spacer ring axially.
4、 Measure the gap width between the outer ring end face and the bearing box cover plate to determine the thickness of the corresponding sealing gasket.
Multiple sealed bearings are marked with the post code XRS.
