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