<p>A radial lip seal (10) is mounted within a split circular seal housing (16) that is configurated to fix the axial placement. The radial lip seal includes an annular seal body (12) having a channel disposed along a seal body outside diameter. The annular seal body which is divided into at least two similar semi-annular sections that are each connected together at end portions. The seal body formed from such sections includes a sealing lip (24) that extends radially inwardly from the body for slidable sealing contact around a rotatable shaft (14). An energizer (30) is seated within the channel. The energizer is interposed between the seal body and the seal housing to both allow the seal to move radially a desired distance within the seal housing in response to seal thermal expansion and contraction, and to provide a leak-tight seal therebetween.</p> |
