Abstract: A bearing assembly engaged with an end of a rotatable shaft. The assembly includes a hub defining a first bore extending between a first opening at a first end of the hub and a second opening at a second end of the hub. A bearing sleeve engaged in the first bore defines a second bore. The shaft's end is inserted through a first opening in the second bore. A sealed bearing located between the bearing sleeve and the hub's interior surface enables relative rotation therebetween. A first sealing mechanism seals the first bore's first opening and a second sealing mechanism seals the second openings of both of the first and second bores. The first sealing mechanism includes an L-shaped ring circumscribing the bearing sleeve and a rubber sealing member. The second sealing mechanism includes a hemispherical region and flange secured to the hub by a retaining ring.
