Tilting pad thrust bearings are mechanical components commonly used to support axial loads in rotating machinery. They consist of several pads that tilt to accommodate the changing load direction. Double-acting thrust bearings are a specific type of thrust bearing designed to carry bidirectional axial loads. Unlike single-acting thrust bearings, which can support loads in only one direction, double-acting thrust bearings are capable of accommodating axial forces in both the forward and reverse directions. This characteristic makes them ideal for applications where the direction of axial loads may change frequently. In the present study, a numerical estimation of load-carrying capacity, axial stiffness, and angular stiffness of a double-acting thrust bearing is performed. Axial stiffness refers to the ability of the bearing to resist displacement under an applied axial load. Angular stiffness refers to the amount of restoring moment provided by the bearing pads when a bearing is subjected to a certain amount of journal inclination. The impact of pivot film thicknesses on the bearing load-carrying capacity, axial stiffness, and angular stiffness is also studied.
