Tapered roller bearings consist of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads. The gap of the radial and axial could be adjusted during the process of installation and use. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads.
