SEALING DEVICE FOR A ROLLING BEARING

摘要

A sealing device (1) including a first annular shield (5) fixable to a first bearing ring (3), a second annular shield (6) facing the first and fixable to a second bearing ring (4); an annular sliding sealing lip (10) of the first shield cooperating with the second ring; and at least a first and a second annular non contacting sealing lips (12, 13) of the second shield; the first non contacting lip (12) includes a first portion (15), which extends in projection, and a second end (16), which extends axially and radially projecting from the first portion (15) and is tapered towards a free end (17) thereof in use axially away from the first ring (3) but which come into contact with it axially when the first annular lip (12) is bent towards the first shield (5); the second non contacting lip (13) extends axially projecting from the first shield (6) from the same side as the second portion (16) of the first lip and beyond it and forms towards the first lip (12) an annular collecting channel (18) of possible contaminants which pass beyond the first annular lip.
