A thrust bearing for an electric submersible pump includes a housing including an axial surface and an inner circumferential surface. Holes and bores are formed in the axial surface. The thrust bearing further includes sockets respectively disposed in the holes and pads each including a fluid interface surface. Two open counterbores are formed in each of the pads. The inner circumferential surface radially constrains the pads. The thrust bearing further includes balls each engaging one of the sockets and one of the pads and retaining bolts each including a head and a shaft extending from the head. Each of the shafts is disposed in one of the bores. The thrust bearing further includes biasing members each disposed between a bearing surface of one of the heads and bottom surfaces of two of the open counterbores. The pads are able to pivot on the ball.
