Description: |
| Claim:
The main objects of this invention are to provide an improved seal for rotating members; to provide an improved seal of the cartridge type for sealing members rotating at relatively high speeds; to provide such a seal having an improved outer end closure for retaining lubricant within the moving parts of the seal and preventing the entrance of dust, dirt, or other foreign material to these said parts; to provide an improved cartridge type seal having a floating carrier for an axially facing sealing member; to provide such a seal in which the floating carrier is provided with an improved suspension to maintain the bearing face of the sealing member in a plane perpendicular to the axis of the rotating member being sealed; and to provide such a seal having improved means for urging the sealing member axially into angularly uniform engagement with a shoulder carried by the rotating member. |
