The 3311A SKF is a double-row angular contact ball bearing with solid inner- and outer rings. The design of this bearing type resembles two single-row angular contact ball bearings in O-arrangement but is slightly narrower. Double-row angular contact ball bearings can support high radial forces and axial forces in both directions. The greater the contact angle, the greater the axial load capacity of the bearing.
