The bearing consists of two cages (internal and external) and rolling elements (tapered rollers), connected with a separator.
The design of tapered roller bearings suites for the perception of combined (radial and axial) loads. Tapered roller bearings have a split construction: the inner ring with the rollers and separator create the unit, that can be mounted separately from the outer ring. Tapered roller bearings are metric.
