Abstract

A flexible ball type joint or bearing is constructed by inserting into a generally tubular-shaped rigid outer housing an assembly of an inner rigid member having a curved surface of part-spherical or barrel shape, a layer of elastomeric material surrounding said curved surface, and an annular member the inner surface of which is of a part-spherical or barrel shape to conform generally with said curved surface of the inner rigid member, and said annular member having an outer surface which conforms generally to the shape of the rigid outer housing. Subsequent to insertion of the assembly in the rigid outer housing, the rigid outer housing is adapted to possess a pair of end abutments between which the assembly is located. The outer housing is then subject to radial compression. The annular member is formed of a material of a modulus of elasticity which is higher than that of the elastomeric material and lower than that of the rigid outer housing.
