A reinforced gasket material. A non-metallic scrim layer is interposed between layers of gasket material to provide strength to the gasket material. The layers of the gasket material can include binding agent to aid adhering to each other and to the non-metallic scrim layer. The non-metallic scrim layer can also be coated in binding agent. The layers of the gasket material can include high-temperature sealing material, compressed fiber, exfoliated graphite, or polytetrafluoroethylene.

A method of manufacturing a gasket material may comprise inserting a polymer sheet into a press, and pressing the polymer sheet with a mold comprising opposing arrays of protrusions to define interconnected sealing ridges surrounding an array of indentations on each major surface of the polymer sheet. A gasket material may comprise a polymer sheet comprising a first major surface and a second major surface, the second major surface opposing the first major surface. Interconnected sealing ridges may define an array of indentations on the first major surface of the polymer sheet. Additionally, interconnected sealing ridges may define an array of indentations on the second major surface of the polymer sheet, substantially symmetric to the first major surface.

A molded discrete low stress gasket is constructed of restructured filled PTFE for use in corrosive or severe chemical environments under relatively low bolt loads. The gasket has a gasket surface and includes a raised outer sealing ring and a raised inner sealing ring. The gasket may constructed from a restructured filled PTFE material, with the sealing rings deforming at lower pressures than the remaining portions of the gasket.

An assembly for sealing a rotating shaft and a bearing housing which has a stator, a rotor, and a unitizing element. The stator has at least two portions and an annular engagement flange extending in an axial direction having a groove on a radial side thereof. The rotor has at least two portions and an annular engagement flange extending in an axial direction having a groove on the radial side thereof. The annular unitizing element has at least two portions, a stator engaging member that engages the stator groove, a rotor engaging member that engages the rotor groove, and a rear member having a side edge that engages the stator. A radially outer surface of the unitizing element has two areas of differing diameter, one corresponding to the rotor engaging member and the other corresponding to the rear member.

The compact five ring stuffing box packing assembly (56) includes high density metal inserted braided end rings (64, 66) of graphite which have each been die formed to have angled facing surfaces. Three low density graphite preform rings (58) having angled facing surfaces are contained between the high density braided end rings (64, 66). The facing surfaces of the preform rings extend at a different angle relative to the longitudinal axis of the packing assembly than do the facing surfaces of the braided end rings. The braided end rings provide a support function for the preform rings as well as a stem wiping function.

An apparatus is disclosed for monitoring characteristics of a fluid lubricant contained within a lubricant chamber (32) formed in a wheel hub mounted for rotation about a stationary wheel axle (14). The apparatus includes an annular bearing spacer (40) configured for mounting on the wheel axle between axially opposed inboard (18) and outboard (20) bearings, the annularbearing spacer (40) forming an interior lubricant reservoir (32) between an inner surface of the spacer and the wheel axle, a guide vane (52) for directing lubricant from the lubricant chamber (32) to the interior lubricant reservoir during rotation of the wheel hub assembly about the wheel axle, and a sensor (86) operatively associated with the interior lubricant reservoir for determining a condition of the lubricant.

The present invention relates to a seal (100) comprising an annular sealing body (110) comprising a radially outer peripheral groove (112), an upper load concentrating projection (118a), a lower load concentrating projection (118b), a compression relief region (235) extending from the center of the load concentrating projections to the radially inner edge of the seal, and a compression relief region (130) extending from the center of the load concentrating projections to the radially outer edge of the seal. Additionally, aspects of the present invention relate to a seal retainer (250) comprising a thin metal sheet comprising a seal retaining aperture (252) comprising a reception lobe (254) and a retention lobe (256); wherein the reception lobe has a diameter larger than the outer diameter of the seal to be retained therein, and the seal retaining aperture has a diameter larger than the minimum diameter of the arch portion (114) of the outer peripheral groove.
