Double row angular contact ball bearings correspond, in their design and operation, to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space, and are particularly suitable in applications where a stiff bearing arrangement is required. They can accommodate radial loads, axial loads in either direction and tilting moments. They can operate at very high speeds and are more suitable than deep groove ball bearings for supporting large axial forces.

| Basic dynamic load rating The basic dynamic load rating Cr or Ca is the load which a bearing can theoretically endure for a basic rating life of one million revolutions. This is expressed as pure radial (Cr) load for radial bearings and pure axial (Ca) load for thrust bearings |
15.9 kN |
| Basic static load rating The basic static load rating C0r or C0a is defined as the load that results in a certain value of contact stress at the centre of contact of the most heavily loaded rolling element/raceway. C0r is indicate for radial load-, C0a is indicate for radial load rating. |

| Contact angle The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis |
25° |
| Matched arrangement Angular contact ball bearing can be arrangement in different sets. ----- Back-to-back (O) or Face-to-Face (X) or Tandem (>>) ----- The O- and X-arrangements of two precision angular contact ball bearings makes it possible to take up axial loads in both directions. High axial loads in only one direction are supported by a tandem arrangement. |
