Abstract
Abstract A bearing construction for heavy machines, in particular for steel works converters, having trunnions borne in self-aligning bearings, such as slide-, articulation-, or self-aligning roller bearings. One bearing is fixed in relation to the foundation and the other bearing is movable. The movable bearing rests with a lower housing part provided with a cylindrical roll-off surface on a horizontal foundation plate. The invention constitutes a solution to the problem of accommodating axial movements of a bearing trunnion affected by thermal expansion.
