Double Flank gear rolling test is generally included in final acceptance test. A gear tested on Double Flank Gear Tester is normally the indication of good running properties of the gear and is adequate assurance about the quality of gear.
The readings taken are the validation of center distance between two gears to be inspected or between one gear and one master gear meshing without backlash during one complete rotation of gear.

|Overall without steady||240W 680L 220H|
|Overall with steady (500 between center)||240W 680L 1000H|
The measurement is combined with inspection of composite error and radial run out on the Double Flank Composite Tester during test.
The tooth thickness then appears in its fully effective form on rotation to the axis, the form that is decisive for the meshing condition in the gearbox. This method check the meshing of the gear as this would be assembled; error recorded on the indicator show the compatibility of the gear and hence is the best way to check gears before assembly.
