  • Track pin seal
    Patent number: 4469336
    Abstract: A unitary seal comprises an annular support section formed of a rigid polycarbonate plastic and an annular sealing section formed of a flexible polyurethane elastomer. The support and sealing sections are directly bonded together without the use of an adhesive therebetween to form a unitary seal. The sealing section has an annular lip extending from one side of the support section and adapted for sealing engagement with a member.

  • Process for making dual-material self-bonding lip seal
    Patent number: 4269802
    Abstract: The invention is concerned with a process for forming a unitary seal comprising a support section formed of a high modulus, i.e. rigid high impact strength plastic and a sealing section formed of an elastomeric material, the support and sealing section being directly bonded together without the use of an adhesive therebetween to form the unitary seal. The process comprises contacting a surface portion of the support section directly with a surface portion of the sealing section, under sufficient pressure to assure a pressed contact therebetween, with the sections at a temperature of 50.degree. C.-400.degree. C. for a time sufficient to cause bonding between the contacting surface portions to form the unitary seal.

  • Dual-material self-bonding lip seal
    Patent number: 4066269
    Abstract: The invention is concerned with a unitary seal comprising a support section formed of a high modulus, i.e., rigid high impact strength plastic and a sealing section formed of an elastomeric material, the support and sealing section being directly bonded together without the use of an adhesive therebetween to form the unitary seal. Such a seal may take the form, for example, of a collar of the high modulus rigid plastic with an interior sealing lip of the elastomeric material within the collar and directly bonded thereto. In another sense the invention comprises a process for forming such a unitary seal. The process of the invention comprises contacting a surface portion of the support section directly with a surface portion of the sealing section, under sufficient pressure to assure a pressed contact therebetween, with the sections at a temperature of 50.degree. C - 400.degree. C for a time sufficient to cause bonding between the contacting surface portions to form the unitary seal.

  • Wheel of track assembly of a crawler type vehicle
    Patent number: 3989314
    Abstract: A wheel of a track assembly of a crawler type vehicle has a resilient contacting element fixed about the wheel rim by first and second anchors. The anchors are slidably movable along angular end portions of a rim opening for securing the contacting element to the rim.
