Abstract
Rotor bearings for ESP motors can include anti-rotation tabs configured to engage, for example between a bearing bushing and a stator of the ESP motor. For example, prior to insertion of the rotor bearing within the stator, the anti-rotation tabs may be held in place within axial slots in the outer surface of a bearing bushing using one or more retaining plates. The retaining plates and the bearing bushing may be configured to allow for axial insertion of the retaining plates onto the bearing bushing and then rotation of the retaining plate with respect to the bearing bushing to retain the anti-rotation tab on the bearing bushing. Such systems and methods may be particularly useful for ceramic bearing bushings.
