Patent number: 8979385Abstract: A seal assembly for sealing a radial rolling contact bearing, having a first sealing ring and a second sealing ring, wherein the two sealing rings can be rotated relative to each other about a common axis of rotation and together form a labyrinth seal, wherein a sealing gap of the labyrinth seal that extends substantially radially with respect to the axis of rotation is covered radially by an axial projection of the second sealing ring, and the sealing gap at the axial projection opens axially into a first catch channel of the first sealing ring. A hub of the radial rolling contact bearing forms the second sealing ring. Therefore, the second sealing ring is integrated into the hub flange, which means that the hub flange performs the function of the second sealing ring and to some extent helps to form the labyrinth seal.Type: GrantFiled: November 15, 2011Date of Patent: March 17, 2015Assignee: Schaeffler Technologies AG & Co.

Patent number: 8696211Abstract: A compact cassette seal and a corresponding wheel hearing for a passenger car or truck. The cassette seal has a bent sheet-metal ring which is and/or can be non-rotatably connected to a radially inner component and an annular sealing system which is non-rotatably connected to a radially outer component. The sealing system has a bearing ring and a radially peripheral seal with at least one sealing lip. The seal is secured to the bearing ring and the sealing lips resting on the bent sheet-metal ring in a sealing manner. A radially outer ring end section of the sealing system defines a labyrinth seal with a bent sheet-metal section of the bent sheet-metal ring. The bent sheet-metal section radially overlaps the ring end section on the exterior thereby forming an axially aligned or substantially axially aligned labyrinth seal section of the labyrinth seal.Type: GrantFiled: November 12, 2008Date of Patent: April 15, 2014Assignee: Schaeffler Technologies AG & Co.
