ABSTRACT:
A bushing assembly is disclosed for effecting a pivotal connection of associated first and second members. Notably, the assembly is of an integrally sealed configuration, and includes concentrically arranged first outer and second inner bushings which are sealed by a pair of annular end caps. An arrangement is provided for conveniently lubricating the interface thus formed between the inner and outer bushings, with the sealed nature of the construction significantly reducing the required maintenance. Notably, final assembly of the pivotal connection provided is effected with a suitable adhesive, thus permitting manual or hand-fitting of the various components for final assembly.
