| Number | Title | Issue Date |
| 7070186 | Flanged boot having a rolling bearing interface A flanged boot having a rolling bearing interface suitable for connection to two mechanical components which are movable with respect to each other, in terms of both rotational and axial movements. The flanged boot has a first annular flange at one end and a second ... | 07/04/2006 |
| 6517078 | Face seal device with additional mass for high rotational speeds A face seal device for use with components rotating at a high rotational speed includes a non-rotating face seal ring (5) and a rotary face seal ring (11). The rotary face seal ring is mounted in a loose fit for common rotation with a rotating component a... | 02/11/2003 |
| 5697620 | Seal assembly having first and second seals acting in series To provide a better seal for example in an indexing arm for a machine tool to prevent swarf getting to the rubber seal, an outer spring seal is provided. The seal takes the form a closely wound coil spring formed into a ring and positioned in a slightly e... | 12/16/1997 |
| 4656925 | Face seal A face seal between the rotor and stator of a fluid-operated rotory motor is formed by a seal member formed of a low friction material having a low surface coefficient of friction and a low memory and extruded into sealing engagement with an associated pa... | 04/14/1987 |
| 4559843 | Coupling member for mechanism for converting linear to rotary motion The invention relates to a device for performing rotational movement and comprises a rotatably element such as a cog-sector (3) or the like, arranged in a housing (1). The sector can easily be connected to rotatable machine elements of various kinds by be... | 12/24/1985 |
| 4522410 | Axle or shaft seal with overlapping ring extension members An axle or shaft seal has inner and outer sealing rings for respective fixed connection to the axle or shaft and a structure thereabout with respect to which the axle or shaft is relatively rotatable axially. Each of the inner and outer rings has a pair o... | 06/11/1985 |
| 4462600 | Rotary fluid seals A rotary fluid seal having a flexible sealing ring which floats between relatively rotatable counterface members and has contact faces which bear on the counterfaces under the influence of centrifugal force, such as forms the subject of U.S. Pat. No. 4,34... | 07/31/1984 |
| 4413831 | Face seal with elastomeric axial thrust member A shaft seal device for inhibiting any fluid flow through between two relatively rotating faces, for example, between a casing or the like stationary member and a rotary shaft or the like rotating member extending through the casing or the like stationary... | 11/08/1983 |
| 4396198 | Joint pin seal for a caterpillar track A joint pin seal for a caterpillar track. The join pin seal comprises a support ring of hard elastomer material having a cylindrical inner wall. The support ring is firmly pressed in a housing bore which is adjacent a relatively movable machine part to be... | 08/02/1983 |
| 4348031 | Rotary fluid seals with floating sealing rings A rotary fluid seal, especially an oil seal for a rotary shaft, comprises a sealing ring between axially-opposed divergent frusto-conical counterfaces of relatively rotatable members, preferably casing rings in a self-contained seal unit, the sealing ring... | 09/07/1982 |
| 4348030 | Toggle-action face seal for relatively rotatable members A face seal, such as for a water pump in the cooling system of an internal combustion engine, comprises a rigid sealing ring carried by the free end of a moulded elastomeric sleeve on a mounting cup, the sleeve having at about its mid-length a circumferen... | 09/07/1982 |
| 4323254 | Seals of the type designed to ensure fluid-tightness between two rings of conical bearings The seal is designed to ensure fluid-tightness between the cone and the cup of a conical roller bearing. The seal includes an armature, having a frustoconic bearing surface, fastenable with the cone, a collar stop mounted slidably along the armature and f... | 04/06/1982 |
