  • Publication number: 20070007731
    Abstract: A double lip seal for a dust excluder seal for a cylindrical reciprocating tube connected to a recreational or utility vehicle, wheel and an off-road motorcycle or bicycle. The seal includes an oil side beam generally parallel to the axis of the reciprocating members and having a spring loaded dust excluder lip for engaging the inner cylindrical tube and wherein the spring is protected from dust and dirt by an outer excluder lip that prevents the garter sprung lip from fouling. In addition the lip is designed with a negative R-value which allows the sprung lip to rotate and position the geometry of the lip to act as a dust excluder lip. The protected spring can now compensate for lip wear which enhances the service life of the seal. The seal also includes an air side beam having a second sealing lip engaging the inner cylindrical tube.

  • Publication number: 20060103075
    Abstract: A triple lip seal for reciprocating members, and especially for an inner cylindrical tube connected to a vehicle wheel and an off-road motorcycle or bicycle. The seal includes an oil side beam generally parallel to the axis of the reciprocating members and having at least two sealing lips for engaging the inner cylindrical tube and wherein the forces applied to the seal are balanced between the two lips to resist flattening of the sealing lips against the shaft and to enhance the service life of the seal. The seal also includes an air side beam having a third sealing lip engaging the inner cylindrical tube.

  • Patent number: 5755323
    Abstract: A kit facilitates selecting a bearing, to replace a used and perhaps defective bearing, in that the kit contains the replacement bearing encapsulated in a package that may include related components, such as a seal, dust cover and cotter pin. The package also includes a gauge which will mate with the bearing in the package at a distinguishing diameter on the bearing. One seeking to replace the used bearing fits that bearing at the distinguishing diameter on it to the gauge to determine if they mate in the same manner that the bearing mates with a machine component. If it does, the bearing in the package corresponds with the used bearing sought to be replaced. If not, one continues the comparison until a package is found having a gauge that mates with the used bearing. In lieu of the gauges being on the packages for the kits, they may be on a display which holds the kits.
