A seal with, on the one hand, a support body in the form of a carrier ring with an axial leg and, on the other hand, a sealing washer which is placed or arranged on the carrier ring and which surrounds the axial leg on the outer periphery, said carrier ring being made of a metallic material, wherein the carrier ring is made of a sheet of the HYS type.

BEARING ISOLATOR SEAL WITH TAPERED STATIC SHUTOFF O-RING INTERFACE

A bearing isolator seal having a shut off O-ring is tolerant of axial rotor-stator misalignment and provides an enhanced static seal while minimizing rotational wear. A tapered section of the stator is overlapped by the shut off O-ring. When the rotor is static there is no axial misalignment, and the shut off O-ring is pressed against the tapered section, forming an enhanced seal. During rotor rotation, increased axial misalignment moves the O-ring away from the tapered section, reducing rotational wear. The stator can extend horizontally beyond the tapered section and below the O-ring, so that if the rotor moves beyond a maximum misalignment, there is a “line on line” fit between the stator and rotor. The bearing isolator seal can include labyrinth technology, and the tapered section can include a contour that allows the shutoff O-ring to drag along the surface of the tapered section with no hang-ups or binding.

Rotary kiln seal and method

A rotary seal assembly for a rotary kiln having a hood and a rotary drum with an opening formed between the drum and the hood, and an end. The rotary seal assembly includes a flexible framework arrangement that attaches to the end. The rotary seal assembly includes a riding surface that engages the drum as the drum rotates. The riding surface includes a series of seal segments with each seal segment having a mounting eye positioned to eliminate a fulcrum point at the mounting eye. The rotary seal assembly includes a seal that is supported by the riding surface and is in essentially 360-degree contact with the drum when it is rotating and seals the opening between the drum when it is rotating in the hood to prevent fluid flow into and out of the end. A rotary seal assembly for a rotary kiln having a hood and a rotary drum with an opening formed between the drum and the hood, and an end, includes redundant tension springs which form a complete 360-degree circle around the drum. A method for sealing an opening formed between a drum and a hood.

Shaft seal assembly

A shaft seal assembly for establishing a liquid-tight seal between a steering knuckle and an axle shaft is provided. The shaft seal assembly includes an outer case and a first elastomeric member attached to one another. The elastomeric member has a castellated feature including a plurality of projections extending in a radially outward direction and separated from one another by a plurality of grooves. When the shaft seal assembly is installed in the steering knuckle, a cavity is presented between the steering knuckle and the first elastomeric member. Together, the grooves and cavity allow air to flow from a hub on one side of the seal assembly to a vacuum port in the steering knuckle. The cavity extends circumferentially around the seal assembly, and thus, air flow from the hub to the vacuum port is not dependent upon the orientation of the seal assembly relative to the steering knuckle.

Wheel assembly seal

A wheel assembly includes a spindle; a wheel hub rotatable relative to the spindle; and a seal mounted between the spindle and the wheel hub, the spindle, the wheel hub, and the seal defining a sealed cavity, the seal having a first axial end and a second axial end, the first axial end coupled to the spindle, the second axial end coupled to the wheel hub.
