Abstract
A flap seal assembly for anti-friction bearings wherein the seal components function to retain the lubricant against leakage to the outside and to function to prevent contaminants entering the bearing from the outside. The seal assembly may have a single set of flaps in combination with a dust lip type seal in one form and it may have a double set of flaps in another form. The seal assembly reduces torque drag on the bearing in the dust lip type seal and is torque free in the double flap seal form.
