Tapered roller bearing type code is 30000, tapered roller bearings for the separation of Four-Row Taper Roller Bearing. Under normal circumstances, with tapered especially in the "Rolling bearings tolerance" are involved in the size range of roller bearings between the outer and inner components are interchangeable hundred percent can be used. The angle of the outer ring and the outer raceway diameter has been normalized to the same size and shape provides. When allowed to change in design and manufacturing. To cause between tapered roller bearing outer ring and inner components can be interchanged in common worldwide. Tapered roller bearings are mainly used to bear radial load mainly radial and axial joint load. Compared with angular contact ball bearings, bearing capacity, low speed limits. Tapered roller bearings can withstand axial load in one direction, a direction to limit the axial displacement of the shaft or housing.
The Slewing bearing is one of the key components of engineering machinery.
