    摘要： A hub unit including a hub and a flange integrally formed with the hub, and a seal including a core metal and an elastic body integrally molded with the core metal. The elastic body includes one or more lips in sliding contact with one or both of the hub and the flange. The elastic body includes a molded rubber, wherein the molded rubber contains, as a raw rubber, acrylonitrile/butadiene rubber having an acrylonitrile monomer content of from 26 to 36% by weight. In a first embodiment, the hub unit includes a hub adapted for receiving a shaft and a flange integrally formed with the hub, and the seal is attached to an outer circumference of the hub unit. In a second embodiment, the hub unit includes an inner ring having a raceway surface for receiving rolling elements and an outer ring. The seal seals the space between the inner ring and the outer ring. Furthermore, the seal includes a radial lip in sliding contact with an outer circumferential surface of the hub.
