Abstract A ball or roller bearing with two symmetrical halves, each designed to absorb both radial and axial stresses, comprises an axially split inner ring on a shaft and an axially split outer ring carried by a housing member coaxially surrounding the shaft. The inner ring halves form seats for respective rows of balls or rollers engaging contact zones on the inner peripheral surfaces of the outer ring halves that are offset from these seats in either an axially inward or an axially outward direction. In the first instance, the housing member has an annular disk received in an annular recess or groove of the same axial width which is formed by two confronting peripheral rabbets on the outer ring halves; in the second instance the inner ring halves are rabbeted to form an annular recess or groove receiving an axially coextensive peripheral rib on the shaft. In either case, the two rabbeted ring halves are axially separated by a small gap.
In an assembly of a shaft member and a housing member coaxially surrounding same, the combination therewith of a journal bearing comprising an inner bearing ring carried on said shaft member, an outer bearing ring carried on housing member, each of said bearing rings being axially split into two mutually symmetrical halves, and two axially spaced sets of rotary bodies seated between said bearing rings, one of said members being provided with an annular web received in an annular recess of the same axial width formed by confronting peripheral rabbets on adjoining end faces of the halves of the bearing ring carried on said one of said members, said adjoining end faces being separated beyond said recess by a gap substantially smaller than said axial width, each set of rotary bodies engaging respective halves of said bearing rings along axially offset contact zones with exertion of a thrust tending to narrow said gap.
