  • Patent number: 10253807
    Abstract: A system for elastically compensating for wear, thermal expansion and misalignment comprises a ring located between a housing and a pin in the bore of the housing. The ring has a backing layer, an expanded grid structure having a plurality of openings, a low friction layer penetrated into the openings of the expanded grid structure, and adhesive for bonding the backing layer, expanded grid structure and low friction layer together to provide elastic deformation of the ring between the housing and pin.

  • 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.

  • Patent number: 9022656
    Abstract: A vibration-damping plain bearing composite comprising a sliding layer, a dimensionally stable support layer and an elastic layer. In one embodiment, the dimensionally stable support layer is arranged between the sliding layer and the elastic layer; in another embodiment, the elastic layer is arranged between the sliding layer and the dimensionally stable support layer. The bearing composites are characterized that a ratio of the thickness of the elastic layer tEL to a thickness of the sliding layer tSL is at least 3.
