NTN bearings 7314 7314C/AC/B 7314/DB/DF/DT

The basic angular contact ball bearing:

Angular contact ball bearings support both radial and axial loads through asymmetric races that house the bearing’s spherical rolling elements, also called bearing balls, on an angle. The deeper the angle between the bearing and its axis, the greater the axial load the bearing can carry. Because the axial load is proportionate to the radial load, a greater axial load capacity means less radial load capacity. Angular contact ball bearings come in single- and double-row configurations depending on the direction of loads they carry. Single-row angular contact ball bearings only support axial loads in one direction, while double-row angular contact ball bearings support axial loads in both directions
