Abstract
Sealing device (1) for a rolling bearing (2) which is provided with an inner race (5), which is axially blocked by a blocking element (4) which is suitable for being arranged in direct contact with a feedback element (6); the sealing device presents a support element (9) which is mounted on the inner race (5), an encoder wheel (8) which is installed on the inner race (5) and which is an integral part of the support element (9) itself, and a static sealing element (10), which is also an integral part of the support element (9) and which, in turn, presents two lips (21, 22) which are substantially parallel in relation to each other and which extend opposite the support element (9), a first lip (21) of the two lips (21, 22) extends towards the feedback element (6) and comes into contact with it, and a second lip (22) of the two lips (21, 22) extends towards a frontal surface of the inner race (5) and comes into contact with it.
