A sealed spherical bearing includes a ball disposed in a race, an annular seal extending between the race and the ball, and a retainer secured to the seal. A retainer first leg axially outward facing surface is secured to a seal first leg axially inward facing surface, and a retainer second leg radially inward facing surface is secured to a seal first leg radially outward facing surface. The retainer and the seal are separately formed elements. The retainer and the seal secured thereto is press-fit into a first annular groove of the race such that a first groove radially inward facing surface engages a retainer second leg radially outward facing surface, a first groove axially outward facing surface engages a retainer first leg axially inward facing surface, and the retainer is fixed relative to the race.
