In the case of a general roller testing machine which is- employed at researching the tooth surface fatigue of gear materials, the specific sliding on test roller is constant during a rotation of the test roller. In this report, a new roller testing machine which can give a continuously varying specific sliding to the test roller was developed using an eccentric gear mechanism and its characteristics were elucidated. In this new type machine, the specific sliding of the test roller changes continuously in the ranges of -125% to 0%, -50% to +33% and 0% to +56 %. The minimum oil film thichness between the test rollers changes during a rotation of the roller with the change of circumferential velocity ratio of the roller pair. The change of the tangential force between the rollers during a rotation of the roller depends upon the changes of the normal force and the friction coefficient between the rollers.
