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. 种钻土工具包含主体和旋转构件，所述旋转构件设置在从所述主体突出的突出部上方并且被配置成相对于所述主体旋转。轴承组合件可以设置在所述旋转构件的腔体内。所述轴承组合件可以包含与所述主体耦合的内座圈和与所述旋转构件耦合的外座圈。轴承保持器可以粘附在所述旋转构件的所述腔体内，并且可以将所述轴承组合件保持在所述旋转构件的所述腔体内。所述钻土工
