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.
