Abstract:
A spherical bearing includes a split outer ring having a spherical radially inner facing surface, an axially outward facing shoulder and a radially outward extending first groove formed therein. A first snap ring is snap fit in the first groove. The spherical bearing includes an inner race defining a spherical exterior surface and having a radially inward extending second groove. A second snap ring is snap fit into the second groove. A seal extends between the outer ring and the inner race and includes a retaining ring secured to a second end of the seal. A first end of the seal defines a lip extending radially inward. The lip is seated against the second snap ring. The retaining ring is positioned between the first snap ring and the axially outward facing shoulder. The seal is axially compressed between the axially outward facing shoulder and the second snap ring.
