Abstract: A bearing assembly for accommodating rotation about an axis includes an outer race (2) having a raceway (6) presented toward the axis and an inner race (4) having a raceway (8) presented toward the raceway (6) of the outer race (2) and forming a bore (12) there between. The inner race (4) includes at an end a sealing surface (20) that is inclined away from the raceways (6, 8) and toward the axis. Rollers (16) are arranged in a row between the outer raceway (6) and the inner raceway (8). A seal (22) closes the end of the bore (12). The seal (22) includes a seal case (24) supported by the outer race (2) at its end. A first sealing element (26) is carried by the seal case (24) and bears against the sealing surface (20) on the inner race (4) and forms a first stage sealing contact. A second sealing element (36) is carried by the seal case (24) and forms second stage sealing contact.
