description An earth-boring tool includes a body and a rotating member disposed over a protrusion from the body and configured to rotate relative to the body. A bearing assembly may be disposed within a cavity of the rotating member. The bearing assembly may include an inner race coupled with the body and an outer race coupled with the rotating member. A bearing retainer may be affixed within the cavity of the rotating member and may retain the bearing assembly within the cavity of the rotating member. The earth-boring tool further includes a seal assembly including a sealing element rotationally coupled with the rotating member, the sealing element comprising a first sealing surface. A second sealing surface may be disposed on the inner race, and an energizing element urges the first sealing surface into sealing engagement with the second sealing surface.
