A propeller thrust bearing assembly includes a spherical rolling bearing provided on a shaft and abutting against a shoulder, and a spherical thrust bearing, incorporating a shaft washer fitted on the shaft, a housing washer provided in a housing surrounding the shaft and a set of rolling bodies provided between the shaft washer and the housing washer. A spacing sleeve is provided between the spherical rolling bearing and the spherical thrust bearing, and a lid member is attached to the housing. The lid member is adapted to urge the housing washer against the set of rolling bodies and via the rolling bodies against the shaft washer. The axial distance between the two bearings is such that their force lines meet at a point situated on the center axis of the shaft. The spherical rolling bearing has a taper bore and is mounted on a withdrawal sleeve, and the spacing sleeve has internal threads and is screwed onto the withdrawal sleeve. A tubular member is arranged about the shaft and is adapted to keep the shaft washer pressed against the rear end of the spacing sleeve facing away from the spherical rolling bearing. The tubular member is secured in position by means of a locking nut screwed onto the threads of the shaft.
