Abstract

A universal joint has a single flexible elastic seal inclosing the trunnion body and in contact with the bearings on the trunnion pins to form seals therewith. The trunnion body is provided with a reservoir in the form of a depression or chamber so that the reservoir is positioned between the trunnion body and the seal. Passages may be provided between the reservoir and seal to extend toward the trunnion pins.
