Double-row angular contact ball bearings with angular raceways on the outer rings are of non-separable construction. They are made in multiple series. They feature silent running, high rigidity and ability to transmit simultaneously relatively high radial and axial loads. Comparing to a pair of single-row angular contact ball bearings mounted together, the double-row angular contact ball bearings occupy less space width-wise.
The raceways are designed in such a way that the lines of contact between the balls and the raceways intersect the axis outside of the bearing. They can therefore transmit even relatively significant turning moments.
The bearings are supplied with standard axial clearance and normal accuracy. Bearings with lower or higher axial clearance. as well as higher running accuracy can also be supplied.
