ABSTRACT:
In an electric motor, a shaft12is supported by a sleeve bearing10and axial movement of the shaft12through the bearing10is restricted by an abutment20supported by or as a part of spacer14. The abutment20has a thrust face22which bears against an end face16of the bearing10creating a thrust/bearing interface. The thrust face22has a part spherical profile to accommodate variations in the alignment between the bearing10and the shaft12due to manufacturing tolerances, etc.
