CAE Double row angular contact bearing has the similar inner structure as the double single row angular contact ball bearings in the installation of DB. But as they are rigidity matched, the axial space is smaller. They can bear the loads in both radial and axial directions, which has higher rigidity and which can bear capsizing moment.
    CAE Double row angular contact bearing has bearing with shields (made by stamping steel sheets, with 2z as suffix) and contact-type seals (made by NBR rubber and fixed by steel plate. This kind of seal is installed in the outer groove and contacted well with it. There exists slight pressure between sealing lip and inner groove to form effective sealing, with 2RS as suffix).
