Abstract

[0036] A sealing assembly (1) insertable between a rod and a guiding bush of a shock absorber to form a sealing and guiding unit (30) for the rod, including: an elastomeric ring (7) having a first and a second annular lip (8, 9) which extend axially and radially overhanging; and a reinforcing ring (10) integrally coupled to the elastomeric ring, radially on the side of the first and of the second sealing lip (8, 9); wherein the reinforcing ring (10) is integrally coupled in one piece with the elastomeric ring (7), on the exterior of the elastomeric ring and on the side of a lateral surface (14) thereof facing towards the lips, the reinforcing ring (10) coupling in sliding manner with the rod (2) in use to serve as guide therefor; the sealing ring (7) coupling by interference in use with the guiding bush (3), havihg both the lips (8, 9) cooperating in sliding manner, with the rod, on opposite sides of the reinforcing ring (10).
