Abstract: A seal assembly for sealing the compartment between a rotating member and a fixed element. The seal assembly comprises a first ring fixed to the rotating member, a second ring fixed to the fixed element, and a seal element. The seal element is carried by the second ring and is connected to said second ring by means of a fitted portion; the seal element comprises at least one annular pad having an annular seal edge. The annular seal edge projects towards a coupling portion of the first ring and is adapted to cooperate with the coupling portion along a substantially linear area of contact. The seal element further comprises a spring portion adapted to exert an elastic force on the annular pad so as to push the annular seal edge towards the coupling portion.

Abstract: A gasket for sealing a compartment between rotating and fixed members. The gasket has a first ring; a second ring radially more external than the first ring; a first annular elastomeric element carried by the first ring and defining at least a first annular sealing lip cooperating with the second ring to counter the passage of external contaminants inside the compartment; a second annular elastomeric element carried by the second ring and defining at least a second annular sealing lip cooperating with the first ring to counter the passage of lubricant to the outside; a third ring coupled to the second ring and extending from this latter towards the axis of the gasket; and at least a third annular sealing lip, overhangingly projecting from the first elastomeric element and cooperating with the third ring to counter the passage of external contaminants from the outside towards the first sealing lip.

Abstract: A gasket for sealing a compartment between a fixed and a roto-translatory member. The gasket has a metal support ring adapted to be connected to the fixed member; first sealing means in a position adjacent to a first ambient containing lubricant and defining two first annular sealing lips axially spaced to cooperate with the roto-translatory member and to counter the passage of lubricant/external contaminants between the first ambient and a second ambient connected with the outside; and second sealing means axially interposed between the first sealing means and the second ambient and defining a second sealing lip axially spaced from the first annular sealing lips and adapted to cooperate with the roto-translatory member to counter the passage of external contaminants towards the first sealing lips; the first sealing means comprise two first distinct sealing rings, axially arranged side by side and respectively carrying a relative first sealing lip.

Abstract: A seal assembly seals a gap between a fixed member and a rotating member housed therein, to prevent flow of oil from a first environment to a second environment of the gap. The assembly includes a first ring fitted to the rotating member, a second ring fitted to the fixed member, an elastically deformable seal attached to the second ring and comprising a first lip cooperating in a fluid-tight manner with a first mating portion of the first ring, and a spiral groove on the first lip to generate, during rotation of the rotating member, a fluid-dynamic pumping action to pump oil from a sealing area to the first environment. A second lip of the seal forms a contact seal with a second mating portion of the first ring when the rotating member is stopped, and a configuration detached from the second mating portion during rotation of the rotating member.
