  • Alignments are controlled within the unit simplifying installation.
  • Sealed cylinder ensures low air consumption.
  • Torques can be varied by regulating the supply pressure.
  • Speed of engagement can be controlled by varying the supply flow rate.
  • Single friction face design virtually eliminates drag torque.
  • Axial thrusts are contained within the unit.
  • Ideal for high cyclic duties, tensioning and torque limiting application.
