FIELD: mechanical engineering.
SUBSTANCE: electrical submersible pump in accordance with one or more aspects of the present invention comprises a housing, a stator mounted in the housing, a shaft installed with a possibility of rotation inside the housing, and a rotor bearing, comprising a carbide bearing bushing, attached to the shaft by a metal element. The metal element is designed with a possibility to apply rotational torque to the carbide bearing bushing and with a possibility to transmit an axial load through the rotor bearing in the axial direction in order to prevent an application of the axial load to the carbide bearing bushing.
EFFECT: structure improvement.
