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.

Integrated sealing device for motorcycle suspensions

Sealing device including a first seal and a second seal each having an annular support formed in the manner of a sleeve and delimited by a first and second face which are situated opposite each other and a first and second annular sealing elements; wherein the first and second annular sealing elements are independent and separate from each other and are fixed integral with a first portion and a second portion of the annular support which are different from each other and are made of a first and second elastomer mix, the second elastomer mix being different from the first mix and having a greater hardness and higher elastic modulus; at least one annular sealing element being provided radially on the inside with at least one annular lip which extends radially and axially in cantilever fashion from a first end of the annular support.

Sealing device in particular for shock-absorber stems

A sealing device including an annular reinforcing insert couplable with a wheel hub in use and an annular sealing element carried by the reinforcing insert and including at least one sealing lip cooperating with a spacer carried by a wheel support pin in use; the reinforcing insert delimits an annular chamber arranged directly adjacent to the annular sealing element in axial direction, and the device further includes a shield mounted in floating manner with radial and axial play in the annular chamber, including a first radial end, which extends to the lip and couples in forced manner with the spacer in use, and a second radial end, opposite to the first, which cooperates with the reinforcing insert and with the annular sealing element to create a labyrinth seal in the annular chamber interposed in use between the annular lip and an environment (E) external to the wheel hub.
