The pneumatic motor mounted on the torque wrench permits uninterrupted work from provisional tightening to final tightening. The AC2 series was upgraded to the AC3 series on May 21, 2018.

ACLS100N2 [Overall length 334 mm]

AC50N2 [Overall length 293 mm]

Application

  • For assembly and mass-production.

Features

  • Same features as A with high provisional torque tightening.
  • Regular tightening tasks using an impact wrench plus a torque wrench become part of a single process, greatly improving task 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.
  • LS version comes with limit switch. Thich creates error-proofing (Pokayoke) system when used with CNA-4mk3 count checker (sold separately).
