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. Due to this design feature, rollers move along the center of the raceway surfaces. The tapered rollers are guided by the compound force of the inner and outer raceway surfaces which keep them pressed up against the large rib on the inner ring. A large veriety of these bearings, including single, double, and four row arrangements, are in use both in metric and inch series.
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 induced 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 internal clearances and preload can be set by adjusting the distance between the two bearings' inner and outer rings.
 Single row tapered roller bearings are separable, so both the inner and outer rings can be used with tight fits.
