A scheme for accurately and quickly axially positioning a rotatable member such as the axles of a differential or a shaft supported impeller of a centrifugal pump within a housing or similar support for rotation therein with predetermined axial bearing clearance which is independent of the dimensional variations of the member and support is disclosed wherein a deformable spacing element is associated with each thrust carrying bearing with the adjacent bearing and spacing element being held axially captive between the shaft and a corresponding disc which is slidable relative to the housing and with one disc axially aligned and limited in sliding movement in one common direction opposite the direction from which the rotatable member is positioned by engagement with the housing. Typically there are two discs, one limited in movement toward the interior of the housing and the other limited in movement by the housing. The deformation of the spacing elements is then accomplished by a series of displacements of the discs and shaft relative to the housing.

An arrangement of thrust carrying bearings and deformable spacing elements rotatably supporting an axially extending shaft within a housing, the housing having an interior and an exterior, a critical dimension determining element within the housing interior, and a shaft portion which limits shaft movement in one axial direction, the arrangement including a pair of incompressible discs slidable in the housing and adjacent to the spacing elements with one of the discs being limited in sliding movement in said one axial direction towards the direction of the exterior of the housing and the other of the discs being limited in sliding movement toward the interior of the housing wherein each bearing is adjacent a corresponding spacing element with the spacing element, adjacent bearing and adjacent disc axially captive between the housing and the shaft.
