The unitized shaft seal assembly comprises an outer rigid annular member including an outer annular ring portion with a flange extending radially inwardly from one edge thereof and an inner annular ring portion with a flange extending radially inwardly from one edge thereof, an inner rigid annular ring member having a radially outwardly extending flange extending from one edge thereof and a radially outwardly extending flange extending from the other edge thereof, a flexible annular sealing member disposed between the rigid annular ring members, a coiled spring extending completely around a portion of said sealing member for urging an inner surface of the sealing member against a radially outwardly facing surface of the inner annular member, and an intermediate rigid annular member positioned on one side of the assembly and having a radially inwardly disposed portion which is positioned adjacent and axially inwardly of a flange of the inner annular member and an outer radially disposed portion which is positioned adjacent and axially inwardly of a flange of the outer member. The inner annular member has a layer of elastomeric material on the inwardly facing surface thereof which extends around and over one flange of the inner member to form a seal between a flange of the inner member and a flange of the outer member.
