Swing pad journal bearings consist of several segmented pads supported by curved laminates of rubber and metal. The pads swing and tilt because of the radial and circumferential deformation of rubber layer due to the hydrodynamic pressure in the oil film and also the frictional force. This type of bearing is expected to form a superior converging wedge in the oil film if the suitable values of design parameters is properly selected. Therefore, in the design of swing pad joural bearing, many parameters must be considered. The present paper evaluates such design papameters as the preload factor, the number of pad and pad configuration in simplified swing pad journal bearing whose pads are supported by a single layer of rubber. As the results, the swing pad bearing with lower preload factor and fewer number of pads is found to have superior performances. Furthermore, pad configuration and bearing temperature is found to affect the static characteristics in swing pad journal bearing.
