The structure of NTN double row angular contact ball bearings is designed by arranging two single row angular contact bearings back-to-back in duplex (DB) to form one united bearing with a contact angle of 25°. These bearings are capable of accommodating radial loads, axial loads in either direction, and have a high capacity for momentary loads as well.
