Abstract
An electric submersible motor radial support bearing is described. An electric submersible motor includes a motor shaft extending longitudinally through a stator bore, the motor shaft bendable out of alignment with a longitudinal axis of the stator bore, a carrier keyed the stator bore, each rotor section of the motor separated from an adjacent rotor section by a roller bearing including a rounded roller cage between a rotatable inner race and a non-rotatable outer race, the inner race inward of the roller cage and rotatably secured to the motor shaft, the outer race having a curved inner diameter (ID) forming a roller cage socket, an outer diameter (OD) of the outer race non-rotatably secured to an ID of the carrier, the roller cage and outer race forming a spheroidal joint as the roller cage pivots off the longitudinal axis of the stator bore as the motor shaft bends.
