Abstract
A submersible pump electrical motor has a stator with a stator bore, a shaft with rotor sections in the stator bore, and a shaft bearing between rotor sections. The bearing has a bearing body having a hub and centralizing arms circumferentially spaced around the hub. Each of the arms curves and is biased against the stator bore wall. A tab on at least one of the arms engages a slot in the stator bore wall. The bearing body, the hub, and the arms are formed of a single-piece monolithic metal that undergoes elastic deflection of the arms when the bearing body is installed in the stator bore.
