Abstract
A sealing assembly used for a wheel bearing of automobiles in order to prevent ingress of contaminating agents such as water or dust into a bearing. The sealing assembly includes an inner annular element, an outer annular element, a seal rubber, and grease. More particularly, the sealing assembly adapts a particularly shaped inner annular element. Additionally, the seal rubber includes a plurality of projecting lips and an uppermost lip of the seal rubber comes in contact with an outer surface of the inner annular element to enlarge the grease containing area and improve the isolation of the bearing by preventing the leak of grease from the sealing assembly and ingress of contaminating agent into the bearing.
