ABSTRACT:
A unitized oil seal assembly (20, 220, 320,420) has a sealing disk (34, 234, 334, 434) fabricated of a single water of PTFE-based material that is split along its radially outer edge to define a pair of split sections, one of which (48, 248, 348, 438) is fixed to an outer annular carrier member (30, 230, 330, 430) and supports the other split section (50, 250, 350, 450) and an unsplit section (52, 252, 352, 452) in sealing engagement with corresponding sealing surfaces of a wear sleeve (32, 232, 332, 432) to exclude contaminants and retaining lubricant, respectively, from passing by the seal assembly (20, 220, 320, 420).
