Double-row ball bearings with angular contact correspond with their construction and function to a pair of single row ball bearings with angular contact in „O“ - type configuration. They have rather deep raceways on both rings and may not be disassembled. In case of „E“ type construction, a lubrication bore is made on one side.
With optimal size of the balls and their conformity to the raceways relatively high load ratings are achieved. They can carry axial and radial loads in both directions and are suitable even for high rotation rate. In case of “E” type bearings assembling, it must be done so that the prevailing axial force acts on the ball row on the side without the filling groove.
