  • Sleeve for shaft seal
    Patent number: 5489105
    Abstract: A shaft sleeve for a mechanical seal assembly having fixed radial lugs for rotationally anchoring one seal ring on an inboard side of the sleeve and depressible anchors for rotationally anchoring a second sealing ring on an outboard side of the seal assembly, the depressible anchors allowing sealing rings and holding rings and other component parts to pass from an outboard side to an inboard side by depressing the flexible anchors radially inwardly. The flexible anchors also fix in axial position a collar which mounts the outboard rotary seal ring. The sleeve provides for advantageous stacking of ring components onto the sleeve for assembly of the seal assembly.
