Sealing device

A sealing device used for a bearing that includes an outer race, an inner race, and rotatable members provided between the outer race and the inner race, the inner race including a flange that faces an edge face of the outer race,

• the sealing device comprising:
• a cylindrical portion fixed to an inside of the outer race;
• an extension portion that extends radially outward of an outer surface of the outer race from an end of the cylindrical portion, where a part of the extension portion contacts the edge face of the outer race;
• a first protrusion that is annular and extends toward the flange from an outer edge of the extension portion, wherein an outer surface of the first protrusion defines a radially outermost surface of the sealing device and extends generally parallel to a central axis of the cylindrical portion;
• and
• a second protrusion that is annular and extends toward the flange from a portion that is a part of the extension portion and is radially inward of the first protrusion,
• wherein the second protrusion is positioned radially outwardly of the outer surface of the outer race.
