In this paper the influences of atmospheric gas such as oxygen or argon upon seizure are investigated. The hydrostatic journal bearings are used as a test apparatus. Oxygen and argon were used as a lubricant in bearing test process. Bronze bearings finished by lapping are used under the combination with steel shafts finished by honing. It was clarified that the process of gas makes an important role for frictional force, origin of debris and the seizure. On the other hand, plastic deformation of the asperities of surface roughness by rubbing action seemed to be a main reason for seizure of similar materials of steel. The surface finishing influences upon the origin of debris and the seizure superior to atmospheric gas.
