Description: |
| Claim:
Known rotary shaft seals include expansible bellows for sealing the stationary seal ring to a housing and for maintaining this ring against -a mating ring on the shaft. This type of shaft seal employs an axially expansible and contractible bellows, usually made of metal, around the shaft and sealed at its opposite ends to the stationary seal rings and the seal casing. The bellows accommodates axial movement of the stationary seal ring and provides an absolute secondary seal while acting as a resilient biasing means to hold the stationary sealing ring against the shaft carried rotating mating ring. |
