Abstract
A swivel bearing unit may have a stationary radially outer ring and a rotatable radially inner ring. The swivel bearing unit may further have a double row of rolling members interposed between the radially outer ring and the radially inner ring, a casing, inside which the rings of the bearing unit are housed, and a sealing device. The sealing device may include an elastomer seal co-molded onto a shaped metal screen stably anchored to the housing. The elastomer seal may be provided with a first radial lip and with a second axially external radial lip. Both the first radial lip and the second radial lip make sliding contact by respective contacting edges with a radially external surface of the radially inner ring. The first radial lip may have a thickness (SP) greater than a thickness (SP) of the second radial lip.
