Abstract: A multi-purpose seal assembly for a gas-pressurized spring including a rigid positioning unit and an elastomeric body portion covering part of the positioning unit. The positioning unit is of generally annular form with a cylindrical outer diameter alignment surface and an inner diameter cylindrical guide surface. The elastomeric body portion includes spaced apart bevelled surfaces tapering toward each other to define an annular, radially outwardly acting static seal lip, and at least one pair of bevelled surfaces tapering towards each other to define a radially inwardly acting primary sealing lip.

Abstract: An oil seal unit including an elastomeric sealing lip portion and a casing portion made from a rigid material and having a mounting flange, a radially extending, offsetting flange, and an annular inner mounting bead formed by folding at least two thicknesses of the casing material upon each other so as to form first and second inclined flange portions connected to each other by a bight portion, one of the thicknesses terminating in an edge portion and with the bight portion presenting a rounded exterior surface portion directed generally toward the sealed region and the inner diameter of the seal, the sealing lip portion having air and oil side surfaces meeting each other along a circumferential locus to define a seal band, and having another portion bonded to and completely surrounding an inner margin of the radial casing flange and the exterior surfaces and edge portion of the material thicknesses forming the bead, to provide a bonded area adapted to resist failure under the application of high pressure.
