A ball or roller bearing with two symmetrical halves, each designed to absorb both radial and axial stresses, comprises two axially abutting inner rings on a shaft and two axially abutting outer rings in a housing wall coaxially surrounding the shaft. The inner rings form seats for respective rows of balls or rollers engaging contact zones on the inner peripheral surfaces of the outer rings that are offset from these seats in either an axially inward or an axially outward direction. In the first instance, the housing wall has an annular groove aligned with an annular recess or groove of the same axial width which is formed by two peripheral rabbets on the outer rings; in the second instance the inner rings are rabbeted to form an annular recess or groove aligned with an axially coextensive peripheral groove on the shaft. In either case, the two aligned grooves form an annular channel of rectangular cross-section occupied by a destructible retaining ring of plastic material whose axial width is equal to or slightly less than that of the channel and which can be molded in situ.
