Abstract
An electrical submersible pump assembly for pumping well fluid from a well has a motor and a pump. The motor having a motor shaft that drives a pump shaft of the pump. A thrust bearing unit between the motor and the pump has a thrust bearing shaft that rotates a thrust runner in sliding engagement with a non-rotating thrust bearing base. A pump shaft coupling couples the thrust bearing shaft with the pump shaft. A motor shaft coupling couples the thrust bearing shaft with the motor shaft. At least one of the couplings has a one-way clutch that allows forward direction rotation of the thrust bearing shaft and prevents reverse direction rotation.
