Single row tapered roller bearings are separable, so both the inner and outer rings can be used with tight fits.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.
