Abstract
A seal assembly for a bearing includes an inner seal member that has an annular ring with a first lobe extending therefrom and a seal receiving surface on a leg extending axially from the annular ring. The seal receiving surface has two seating areas. The seal assembly includes an outer seal member positioned radially inward from the leg and axially outward from the annular ring. The outer seal member has a pivot member which has a second lobe extending outwardly therefrom. The seal assembly includes a retaining ring that has a circumferential groove formed therein. The pivot member is pivotally seated in the groove so that the second lobe is moveable between the two first seating areas.
