ANGULAR-CONTACT BALL BEARINGS
Double-row
Double-row angular-contact ball bearings correspond to a pair of single-row angular-contact ball bearings. These types can carry heavy radial and axial loads in both directions.The bearings are specially applied,when the high rigidity is required.
Double-row angular-contact ball bearings may have one-side filling slot, by this main load should be carried by the raceway, which doesn't have filling slot.
To carry special heavy axial loads, variable to direction, double-row angular- contact ball bearings with split inner rings ( DB ) are applied.
