  • BEARING LAMINATE COMPRISING A FOAM LAYER
    Publication number: 20220355582
    Abstract: A bearing laminate can include a metal support layer, a foam layer overlying the metal support layer, the foam layer including a polymeric foam; and a sliding layer overlying the polymeric foam layer, the sliding layer comprising a polymer matrix. Bearing articles made from the bearing laminate can have exceptional damping properties, such as a high damping ratio combined with a low dynamic stiffness.

  • Laminates with fluoropolymer cloth
    Patent number: 10307991
    Abstract: A laminate includes a metal substrate and a sliding layer overlying the metal substrate. The sliding layer can include a polymer fabric. The polymer fabric can include first polymer P1. The sliding layer can further included a melt-processable matrix polymer. The melt-processable matrix polymer can include a second polymer P2. In embodiments, either P1 or P2 is a fluoropolymer. The sliding layer can further include a filler. In embodiments, the total amount of fluoropolymer and filler in the sliding layer is at least 30 vol %.

  • Maintenance-free slide bearing with a combined adhesive sliding layer
    Patent number: 9803690
    Abstract: Slide bearings and methods of producing slide bearings are disclosed. The slide bearing has a metal support and a sliding layer. No other layer is in contact with the sliding layer. The sliding layer is applied directly to the metal support. The sliding layer comprises a mixture of at least two polymers P1 and P2, wherein P1 is a fluoropolymer. P2 is a non-fluorinated thermoplastic polymer.

  • Maintenance-free slide bearing with FEP or PFA in the adhesive layer
    Patent number: 9297416
    Abstract: Slide bearings and methods of producing slide bearings are disclosed. The slide bearing has a metal support, an adhesive layer and a sliding layer. The adhesive layer is applied directly to the metal support. The adhesive layer comprises a blend of at least two fluoropolymers P1 and P2, wherein P1 is selected from perfluoroalkoxyethylene (PFA) or tetrafluoroethylene-hexafluoropropylene (FEP). P2 is different from P1 and can be a fluoropolymer.
