ABSTRACT:
A method for assembling bearing rings in an elongated sleeve member consisting of the steps of forming a roller shell with three sections of varying wall thicknesses separated by angular circumferentially extending shoulders, deforming the shoulder between the middle section and one end section to form a ring-shaped radially, inwardly directed projection by axial displacement of the shoulder. A bearing ring is inserted in the interior of the shell member so that one axial end face engages the first radially oriented projection formed and deforming the shoulder between the middle section and the other end section to form a second radially inwardly directed projection by axial displacement of the shoulder which confronts the opposite axial end face of the bearing ring.
