ABSTRACT:
Improved bore retention of a lip seal is provided by case structure having a series of interrupted, short angularly outwardly deflected portions barely covered by an elastomeric covering. The angularly outwardly deflected portions and the elastomeric covering are proportioned carefully relatively to the bore, which is provided with an annular groove at one end that aids in retaining the seal, in cooperation with displaced elastomer and the outwardly deflected case portions.
