  • Patent number: 9440489
    Abstract: A cassette seal includes a first and a second ring, wherein the axial sections and the radial sections of the first and second ring are aligned approximately parallel to one another, forming an interior in which a sealing arrangement arranged on the first ring engages in the direction of the second ring and a gap is formed between the radial section of the first ring and the axial section of the second ring. A fixed additional element extends on the side of the axial section of the second ring facing away from the interior, and the rises in the direction of the radial section of the first ring above the axial section of the second ring with a protrusion. The protrusion has a downward slope in the direction of the second ring, to form the gap.

  • Patent number: 8979385
    Abstract: 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.

  • Patent number: 8696211
    Abstract: 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.

  • Publication number: 20130127119
    Abstract: A sealing assembly for sealing a rolling bearing, between a first and a second bearing part, where the two bearing parts are rotatable relative to each other and form therebetween both an axial space and a radial space. The sealing assembly includes: A contact member having a mounting section for attachment and a ring-shaped contact section for positioning the contact member on the second bearing part, and a carrier mountable to the first bearing part and has an elastic member forming a first axial sealing lip and/or a radial sealing lip. The contact member and a radially extending portion of the second bearing part together form a first collecting channel, and that an opening leading into the first collecting channel should be at least partially defined by an end section of the contact member.

  • Patent number: 8152381
    Abstract: A rolling bearing which has a sealing arrangement and a sensor component, particularly an encoder, which is fitted with a mounting flange. The rolling bearing further has an inner ring and an outer ring between which rolling members are arranged. The sealing arrangement is equipped with at least one sealing element between the inner ring and the outer ring. In order to provide a rolling bearing which can easily be retrofitted with a retrofit sensor, particularly a retrofit encoder, and is well protected against environmental influence, the sensor component that is fitted with the mounting flange is designed as a retrofit part, while at least one water discharge port is disposed in the region of the mounting flange.

  • Patent number: 8042814
    Abstract: The seal for sealing off the bearing interior of a bearing has a first sealing lip angled outward from a base of the seal and forming a first sealing contact, and a second sealing lip angled inward from the base and forming a second sealing contact. An annular chamber is formed between the first sealing lip and the second sealing lip. The first sealing lip has at least one ventilation opening which leads into the chamber from the outside. The ventilation opening is positioned at the first sealing contact.
