Standard double row deep groove ball bearings are the type 4200A and 4300A. Type A bearings have no gap for loading ball, instead of the 2 Nylon holders which insert from both sides of bearing. Double row deep groove ball bearing not only has 1.62 times of radial loading capacity than that of single row deep groove ball bearing, but also can bear the axial concentrated load.
