Abstract
A sealing device is to be fitted at a side of a bearing unit in order to seal a gap () between a stationary race () and a rotatable race () of the bearing unit. The device includes a relatively rigid reinforcing insert () of disc-annular shape, and a gasket () of relatively soft rubber or elastomeric material, over-moulded or vulcanized onto the insert (). The gasket forms two opposite peripheral sealing portions () intended to perform a static sealing action against the rotatable race () and a dynamic sealing action on the stationary race (), respectively. The insert () includes magnetized or magnetizable material for forming, at predetermined angular zones or fields, a sequence of alternate and/or spaced north/south poles, in order to act as an encoder.
