What is the feature of taper roller bearing?

Tapered roller bearings consisting of inner ring with roller and cage assembly can be mounted separately from the cup. The projection lines of all the tapered surfaces meet at a common point on the main axis of the bearing. The rollers are guided by the cone (inner ring) back-face rib.The design of tapered roller bearing can support a combined radial and axial load. The larger the half angles of these cones, the larger the axial force that the bearing can sustain. Internal clearance for this bearing type is established during mounting by the axial position of the cone relative to the cup.
