ABSTRACT:
A method of manufacturing a spherical bearing having an outer cylindrical member, an intermediate yieldable plastic member enclosed and supported thereby, said intermediate member having a concave inner surface and a spherical ball in bearing relationship with said intermediate member, said spherical ball having an outer surface complimentary to said concave inner surface of said intermediate member comprising the steps of preforming the outer member into a truncated conical member having a first radially inwardly annular lip formed at one end thereof, preforming the plastic intermediate member wherein substantially one-half of its inner and outer surface conforms generally to its final shape and the remaining portion of said intermediate member emanates outwardly therefrom, inserting said ball within the inner surface of said intermediate member such that a portion of the convex outer surface of said ball intimately engages the preformed concave inner surface of the intermediate member, inserting the intermediate member with the spherical ball contained therein within the outer member, applying a deforming force to the outer surface of the outer member by die means to form the outer member into a cylindrical shape and to deform the plastic intermediate member completely around said spherical ball and to fill the space between said spherical ball and said outer member, deforming the unformed end of said outer around the intermediate member to form a second radially inwardly annular lip and to complete the bearing.
