ABSTRACT:
A pair of pivoting parts are held together with a pin, with a first part, such as a rod end of a hydraulic actuator, positioned between two flanges of a bracket, with the flanges having surfaces mating with sides surfaces of the rod end. A seal is placed in each of a pair of recesses on the opposite side surfaces of the rod end to provide an annular seal around the surface of the pin as the parts pivot, and also having a flange forming a side seal that seats on one of the mating surfaces of the bracket at a location spaced outwardly from the pin and extending annularly around the pin. The seal portion engaging the pin is spaced inwardly from the respective side surface of the bracket, and the outer annular lip seals a space surrounding the pin to form a pocket to receive grease that is used to lubricate the pin relative to the rod end.
