Double row spherical roller bearings have two raceways in the inner ring and a common spherical raceway in the outer ring. This feature allows the bearing for self-alignment and permits minor incoaxiality of the shaft relative to the housing occurring in mounting, or due to housing shaft deflection under load. This type of bearing is designed mainly to take heavy radial loads. Although it can also take axial loads in both directions, it is not recommended for taking axial loads only. The relative axial displacement of the shaft to the housing is restricted to the axial clearance limit of the bearing. This type of bearing possesses much higher load carrying capacity than double row spherical ball bearing and is more suitable for taking heavy and shock loads.
