ABSTRACT:
A motor for a submersible well pump has rotor sections spaced apart from each other with bearings located between. The bearings support the shaft of the rotor within a stator. The bearings have a body made up of thin, circular metal nonmagnetic disks. The disks are stacked axially. A resilient member mounts to the bearing body for engaging the inner wall of the stator to prevent rotation of the bearing.
