摘要： A unitized seal assembly (100) for use with roller or ball bearing assemblies is disclosed. The unitized seal (100) assembly includes, among other things, a radially outer ring (60) and a radially inner deflector ring (70). The outer ring (60) includes a first shield element (64) which defines a first sealing face (66). The radially inner deflector ring (70) includes a second shield element (74) which defines a second sealing face (78). The second sealing face (78) is dimensioned and configured so as to correspond to the first sealing face (66) such that when the first shield element (64) is positioned in a non-contacting proximity to the second shield element (74), a circuitous sealing labyrinth is formed between the first sealing face (66) and the second sealing face (78).

摘要： Disclosed is a labyrinth seal assembly (100) for sealing an annular gap defined between a bore of a housing (90) and an outer surface of a cylindrical shaft (80), wherein the housing and shaft are relatively movable. The seal assembly includes radially inner and radially outer shield rings (60) (70). The radially inner shield ring (70) has an inner surface which is adapted and configured for support by the shaft. The radially outer shield ring is partially disposed within the sealing channel (72) of the inner shield ring. The outer shield ring includes a casing member, foam seal elements (64a, 64b), and a shield element retainer. The foam seal elements depend radially inward into the sealing channel so as to form a circuitous sealing labyrinth therein. The seal elements are formed preferably from polyurethane. A highly viscous fluid is disposed within the circuitous sealing labyrinth.
