Size reduction achieved by integrating the Z50 AXIS and Master control units
into a single unit. Compatible with a wide range of tools covering 5 to 400N･m.
*1 Comparison of the volume of MAU55/AU55 with other ESTIC control units.

Cycle time is reduced even further! Industry's fastest class
The processing speed of the control unit has been increased from the Z50 series.
Screw tightening process cycle time has been shortened, greatly contributing toproductivity improvements.
*2 These are the results of measurements performed in our own environment. Results may differ depending on tightening conditions and settings.
