      We can summary this study in two parts. In the experimental part; under the dynamically loaded journal beraring which run in the radial journal bearing test ring has been applied six different load. All of loads vertical, horizantal components and polar load diagrams have been taken photographs from the osciloscope screen. Furthermore in the radial journal bearing which is ifluenced under the dynamically loaded, parts has been improved and manufactured to determine shaft center how a follow orbit. To determine the shaft center orbit four capacitive inductive contactless transducer (Tr 10) has been joined with Whesthon biridge electricity circuit. And then shaft center orbits for each load examples have been taken photographs as polar and vertical, horizantal components from the osciloscope screen.

      In the theoretical part; first of all two computer programs which are allowed what sort of orbit to follow in the journal bearing have been run and improved. And then in the experimentals to be obtained loads photographs have been analysised to shaft angles, load angles, load values and bearing geometries as input computer programs data. Program has been run different shaft speed, different bearing ratio, different relative bearing ratio, different viscosity values and for different load amplitude values. After this program output files heve been used to draw shaft center orbit graphics. Furthermore shaft angle value which are at the maksimum eksantricitiy ratio value have been also drawn circumference pressure distribution graphics.

      Consequently, shaft center orbit and polar load diyagrams drawn theoreticaly and resulted experimentaly heve been compared whith each other, seperetaly. It vas concluded that the results were agreement with each other. Moreover, it was determined that the graphics obtained by changing bearing parameters were also fitting to literature.
