A180N [Overall length 489.5 mm]

Application

  • For assembly and mass-production.

Features

  • Replaces conventional two-step tightening process with one tool in great efficiency.
  • Provisional tightening is applied using the air motor operation, and completed in high accuracy by manual torque wrench operation.
  • Accuracy improved with final tightening completed by manual torque wrench work.
  • Changing tightening torque is easy with the N・m unit scale.
  • Easy calibration with torque wrench tester.
  • L version comes with limit switch. LS version available with limit switch, which creates error-proofing (Pokayoke) system when used with CNA-4mk3 count checker (sold separately).
  • Applicable for international use including the EU region.
