Definitions

  • FIGURE 2 shows in cross-section, a section in detail of the seal as it would appear after removal from the mold.
  • the elastomeric body of the seal 42 is bonded to the seal metal case 20, as at 60, and to the embossed PTFE wear insert having the fluted surface 44 as at 62.
  • Dotted line 66-66 indicates where the excess rubber of the "hat" is cut away or trimmed from the seal body 42.
  • FIGURE 5 shows a cross-sectional view of another embodiment of a seal similar to the one shown in FIGURE 4 in which the elastomeric body 42 of the seal has been extended axially inwardly and angularly away from the primary seal at 44 to form an auxiliary dust excluding lip 74.
  • the dust excluding lip 74 can greatly extend the useful life of the seal. More accurately, it should be stated as greatly extending the life of the shaft which is the "other half" of the seal. Without such an auxiliary lip 74, dirt has a tendency to get worked into the area between the PTFE wear insert 26 and the rotating shaft 72.
