Polytetrafluoroethylene (PTFE) composites are extensively utilized in tribological applications. In bearing applications, they have found use in journal bearings, bearing pads, lubricants, and other ...

Journal bearing design is complex. It involves optimizing clearances, bearing length, minimum film lubricant, viscosity, flow rate, and inlet slots. Design equations are available, but their solution ...

This paper presents a novel analytical solution for journal-bearing viscoelastic lubrication using the perturbation method. The nonlinear Giesekus model was used for the constitutive equations to ...

Tilting pad journal bearings are used in turbomachinery such as turbo compressors, turbo gears, gas turbines, or steam turbines. There is an ongoing and growing customer demand for bearings with ...
