Tapered roller bearings are designed so the tapered vertex of the raceway surfaces of the inner and outer rings and rollers converge at one point on the centerline of the bearing. The tapered rollers are guided by the compound force of the inner and other raceway surfaces which keep them pressed up against the large rib on the raceway surfaces which keep them pressed up against the large rib on the inner ring.
These bearings are constructed to have a high capacity for radial loads,axial loads,and combined loads.The larger the contact angle,the greater the axial load capacity becomes.When a pure radial load is placed on the bearings, an included load in the axial direction is also generated,and so these bearings are generally used in pairs arranged face to face. When used in pairs,proper between the two bearings’ inner and outer rings.
Single row tapered roller bearings are separable,so both the inner an outer rings can be used with tight fits.
