Double-row Angular Contact Ball Bearing
Double row angular contact ball bearings can endure radial load and also the axial load on both two directions. They can limit the axis and shell bilateral axial movement with 30 degree contact angle. And also double row angular contact ball bearings can provide higher rigidity configuration and endure overturn moment.
