摘要： 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.

摘要： A sealing assembly for bearings, in particular for use in agriculture, the sealing assembly having a first shield, which extends from an outer surface of the inner ring to an inner surface of the outer ring, and is mounted on the outer surface of the inner ring, and a seal with a plurality of contact lips supported by the first shield, and provided with a predetermined number (N) of contact lips arranged in series axially next to one another. The contact lips may lie, when in a respective pre-assembly configuration, in respective planes (P) inclined with respect to a central axis (A) of the bearing, and may have radial lengths decreasing axially towards the bearing.

摘要： A sealing system including an annular support, an annular sealing element and an annular shielding element; a first and a second lip of the sealing element interact slidingly with an abutment surface of the shielding element and each include: a root portion which extends perpendicularly in cantilever fashion from a flange portion of the annular support; a flexing portion, which extends in cantilever fashion from the root portion in an oblique direction with a thinner radial thickness, delimited by an annular internal surface facing the abutment surface and by an annular external surface facing towards the support, consisting of surfaces of revolution generated by segments of circumference; and a contact portion including a wedge-shaped overhang and a step portion flanking the overhang, which forms with the abutment surface a first and a second angle (α, β), the first angle facing the annular support and being smaller than the second angle.
