A sealing assembly having a seal casing. A decreased diameter portion extends inboard from at least a portion of a first end portion of the substantially cylindrical portion and an axially extending portion extends inboard from at least a portion of a second end portion of the decreased diameter portion of the casing. One or more first sealing portions having one or more static sealing ribs extend from at least a portion of an outer surface of the substantially cylindrical portion. One or more second sealing portions are integrally connected to at least a portion of the decreased diameter portion, the axially extending portion and/or an inner surface of the substantially cylindrical portion. The one or more second sealing portions have a retaining member sealing surface with one or more sealing member retention ribs extending from at least a portion of an outer surface of the retaining member sealing surface.

Cushion holes are provided in cover members, tubular cushion rings are provided on a piston and a piston rod so as to be insertable into and withdrawable from the cushion holes as the piston moves, cushion packings capable of slidably contacting the outer circumference of the cushion rings are mounted to be movable in an axial direction, in mounting grooves formed on inner walls of the cover members constituting the cushion holes, the cushion packings each include a plurality of protrusions extending from the outer circumferential surface to the side surface near the piston and disposed circumferentially alongside one another, and cushioning grooves that extend in parallel with the axis of the cushion rings and whose cross-sectional area changes are formed on the outer circumferential surface of the cushion rings.

A self-lubricating flexible carbon composite seal includes an annular body formed from a flexible carbon composite.

A sealing device for a motorcycle suspension provided with an armature on which an elastomeric covering is mounted, said covering comprising a first radially outer portion, for providing a dynamic seal with a first component of the motorcycle suspension, and a second radially inner portion for providing a guide and a static seal with a second component of the motorcycle suspension, on which the sealing device is mounted; the elastomeric covering is integrally connected to the armature and the radially outer portion has at least one first, flexible, annular sealing lip which projects, protruding in a radially and axially external direction so as to cooperate, during use, in a sliding manner, with a surface of the first component of the motorcycle suspension.
