<p>A flap seal assembly for an anti-friction bearing comprising a cone (10), cup (12) and a plurality of tapered rollers (14) restrained by a cage (15). The bearing has a seal assembly whose components (16,20,22) function to retain the lubricant against leakage to the outside and which functions to prevent contaminants entering the bearing from the outside. The seal assembly may have a single set of flaps (22) in combination with a dust lip type seal (23) 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.</p> |
