MG60CN [Overall length 287 mm]

MF12N [Overall length 441 mm]

Application

  • For automatic tightening system / multi-spindle tightening system.

Features

  • Torque remains stable regardless of air pressure fluctuations, since torque control is performed mechanically.
  • Torque setting is easy to adjust by knob and scale.
  • Upon reaching the set torque, the internal toggle clicks and automatically stops operation, while the micro switch turns on simultaneously to signal tightening completion.
