Patent number: 12196267Abstract: 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 (SP1) greater than a thickness (SP2) of the second radial lip.Type: GrantFiled: September 22, 2022Date of Patent: January 14, 2025Assignee: AKTIEBOLAGET SKFInventors: Gianni Alvise Cognolato, Pietro Fabio Picatto

Patent number: 8561996Abstract: The bearing seal assembly (50) includes a metal shield (70) and a resilient multi-lip sealing gasket (60) secured to the metal shield. The metal shield is supported in use by an outer ring (20) of a rolling contact bearing and includes a diagonally extending central portion (72). The sealing gasket (60) provides a number of contacting lips (62-64) facing an inner ring of the rolling contact bearing. A first, main contacting lip (66) exerts a first radial load on the inner ring. A second contacting lip (62) extends from the first lip (66) and exerts a second radial load on the inner ring lower than the first radial load. A third contacting lip (64) is on the opposite side of the second lip (62) with respect to the first lip (66) and exerts a third radial load on the inner ring lower than the first radial load but greater than the second radial load.Type: GrantFiled: May 25, 2009Date of Patent: October 22, 2013Assignee: Aktiebolaget SKFInventors: Fabio Picatto, Davide Zanghi
