| 277561000 | Intermediate flexible bending portion | 7 |
| 20100133758 | SEALING DEVICE - To effectively and easily suppress squealing noise occurring when a steering shaft is in strong contact with a bumper portion, a sealing device ( | 06-03-2010 |
| 20100187768 | RADIAL SHAFT SEAL, RADIAL SHAFT SEAL ASSEMBLY AND METHOD OF INSTALLATION - A radial shaft seal configured for receipt in a housing and about a shaft to sealingly isolate an air side of the seal from an oil side of the shaft seal is provided. The seal includes a mounting portion and a seal lip having an annular sealing surface extending between an oil side end and a free air side end. An annular bridge is connected to the oil side end of the seal lip by a first hinge and to the mounting portion by a second hinge. The bridge extends from the first hinge to the second hinge in radially overlying relation to the seal lip. A projection extends from the first hinge away from the bridge toward the oil side of the seal to prevent the seal lip from inverting during the oil-side installation assembly. | 07-29-2010 |
| 20100187769 | RADIAL SHAFT SEAL, RADIAL SHAFT SEAL ASSEMBLY AND METHOD OF INSTALLATION - A radial shaft seal configured for receipt in a housing and about a shaft to sealingly isolate an air side of the seal from an oil side of the shaft seal is provided. The seal includes a mounting portion and a seal lip having an annular sealing surface extending between an oil side end and a free air side end. An annular bridge is connected to the oil side end of the seal lip by a first hinge and to the mounting portion by a second hinge. The bridge extends from the first hinge to the second hinge in radially overlying relation to the seal lip. An annular projection extends from the mounting portion axially away from the bridge. The projection has an oil side facing the seal lip and confronts the air side end of the seal lip upon the seal lip pivoting about the first hinge. | 07-29-2010 |
| 20130001889 | ANNULAR SEALING ASSEMBLY, IN PARTICULAR FOR INSERTION BETWEEN ELEMENTS SUBJECTED TO AN OFFSET POSITIONING - A sealing assembly for insertion between first and second mechanical elements subjected to offset positioning, including a reinforcement ring and at least one elastomeric sealing element in which the reinforcement ring is at least partially embedded, the sealing element including an annular membrane shaped as a truncated-cone sleeve and free from the reinforcement ring, which membrane obliquely extends to protrude from the reinforcement ring, towards a symmetry axis of the sealing assembly and ends with at least one annular sealing lip intended to slidingly cooperate with the first mechanical element; the membrane has, in radial direction, a relatively thin thickness, thinner than that of the at least one sealing lip, so as to be highly flexible, and a plurality of stiffening ribs formed with the membrane, which extend in the axial direction, parallel to one another, spaced apart from one another to form longitudinally extending radial projections on the membrane. | 01-03-2013 |
| 20130341872 | CHANNELED SPRING SEAL FOR SEALING AN AIR GAP BETWEEN MOVING PLATES - A sealed joint may include a first plate with a seal land, a second plate that moves relative to the seal land, and a seal connected to the second plate. The seal may extend laterally between a first seal end and a second seal end. The seal may include a plurality of seal elements that extend longitudinally between a first seal side and a second seal side. A first of the seal elements may extend laterally from the first seal end towards a first seal segment, which is separated from the second plate by an airflow channel. The second of the seal elements may extend laterally from the second seal end towards a second seal segment, which is located between and engaged with the first seal segment and the seal land. | 12-26-2013 |
| 20130341873 | Radial Shaft Seal Ring - A radial shaft seal ring includes a reinforcement ring and an elastomeric part connected to the reinforcement ring. The elastomeric part carries a sealing lip, which is formed by an annular component connected to the elastomeric part. The annular component has a sealing edge made from PTFE which is formed to sealingly abut on a shaft to be sealed by the radial shaft seal ring. The sealing edge can be formed as a sharp-edged sealing edge that abuts, in linear contact, on the to-be-sealed shaft. | 12-26-2013 |
