ABSTRACT:
A seal assembly including first and second rigid shields and a sealing member carried by the first shield and having a first and second annular sealing lip in sealing engagement with respective sliding surfaces of the second shield. The first sealing lip carries in a radial seat thereof a toroidal spring exerting a radially eccentric thrust on the first sealing lip with respect to an elastic hinge defined by a common root portion of the lips, having a center of rotation located along a line extending through a V-shaped sealing edge of the first lip and forming a 20° to 60° angle with a radial plane. The root portion is defined between two opposite annular recesses having a U-shaped cross-section and bottom walls facing each other, substantially aligned along the aforementioned line.
