Abstract: Seal for rolling-contact bearing, of the type adapted to be fitted in the outer race thereof or in a cavity intended for said bearing, which comprises two sealing lips directed the one radially towards the inner race and the other axially outwards of the seal and bearing assembly. The outer axial lip has a flattened triangular configuration and the edge having the smallest acute angle of this lip acts as a frictional contact element, the edge having the largest acute angle constituting a kind of circular hinge interconnecting the seal body and said lip, the circular edge of obtuse angle creating a reinforcing area between the edges of said lip, its width corresponding to about five times its thickness and its inclination corresponding to about 10* to about 60* in relation to the bearing axis. This seal is also applicable to other rotating members.
