The tilting-pad thrust bearing mainly bears axial loads, it also can bear certain impact loads. It is mainly applied to electric submersible pump unit.
The tilting-pad thrust bearing is made of three layers composite, which are matrix—copper layer—the composite material layer. The matrix of it is made of steel which is treated by special method. The composite material of pad appearance is made of modified tetrafluoroethylene, so it can get the lower friction coefficient and better heat resistance. This kind of bearing is easy to implement hydrodynamic lubrication, because it has special processing technology, high-precision size of pad and proper thickness of oil film.
