Abstract: A sealing element for a face seal assembly including a bellows portion having mounting portions at its axial ends. One of the mounting portions is designed for non-rotational mounting on a component, e.g. a shaft, and the other for retaining an annular face member. The sealing element is formed, on at least the faces thereof exposed to a medium to be sealed, from a plastics material selected from a group of plastics materials comprising PEEK and ECTFE. The sealing element serves for applying a bias force to the annular face member. The sealing element enables the design of an uncomplicated, easily maintained, externally pressurised single action face seal assembly which is particularly suitable for sealing aggressive media.

Abstract: On a radially inner surface of a sealing lip of an oil seal, radiation ray is irradiated to induce chemical reaction in the materials of the sealing lip, to form hard helical portions. The hard helical portions act like a helical groove or rib to pump oil back to oil-side to show an excellent sealing property when there is a relative rotational movement between the sealing lip and a shaft to be sealed, as well as even static sealing ability at the time there is no relative rotative movement.

Abstract: A brush seal designed for use between regions of high pressure differential and in an environment in which there is disturbed flow has a bristle pack sub-divided into a plurality of bristle pack regions with a leaky diaphragm between each region. The brush seal may comprise an assembly of individual seals with diaphragms between them or a single bristle pack which is sub-divided by at least one internal diaphragm. The diaphragms are preferably compliant and designed to allow a predetermined leakage flow between bristle regions. The leakage flow has several functions: it causes the pressure differential across the whole seal assembly to be more evenly distributed, and by providing an amount of flow in each pack this acts to calm the bristles thus helping to ensure each bristle region effectively contributes to the seal performance.

Abstract: A rotary seal assembly is comprised of a collar adapted to be fixedly mounted on a shaft, the collar including a plurality of through going apertures parallel to the axis of the shaft. Drive fingers are slideably mounted within the bores of the collar, an inner end of the fingers being fixed to a pusher ring shiftable toward and away from the collar. The outer end of the fingers extend through complemental apertures formed in a containment ring into a rotary seal component. Springs are biased between the containment ring and drive collar to urge the fingers axially into aligned bores formed in a rotary seal member.

Abstract: A sealing device primarily for sealing off a slit-shaped space between two radially extending surfaces arranged about a shaft and axially displaceable relative to each other along the shaft includes a first sleeve-shaped seal part and an elastically resilient sealing body. The first sleeve-shaped part forms together with the shaft an axially open space facing the cooperating surface. The elastically, resilient sealing body has in an uncompressed state a cross-sectional area and/or a shape deviating from the area and/or shape of the axially open space. The sealing body when subjected to axial forces causing the sealing body surface and the cooperating surface to abut each other is compressed sealingly between the axial space and the cooperating surface, thereby creating a sealing engagement against the entrance of the slit-shaped space and against the shaft.

Abstract: A mechanical end face seal includes one seal ring having two elements, a seal face extension portion immediately adjacent a sealing face and a seal ring body removed from the sealing face.
