The hydraulic actuator HA-1S1 is extremely low - only 50 mm in height. Still, using, for example, any of OK-VISE D-series clamps, it can create 4.4 mm (2 x 2.2 mm) clamping stroke. Single acting hydraulic function ( with powerful return spring ) is simpliest to operate , but the actuator can also used in a double acting mode. If so, the return spring can also be removed.

  • Max pressure 350 bar, max force 1.7 metric tons
  • Two G 1/4 ports for clamping and two for unclamping

  • Metal plug to close extra ports
  • Push spring (for single acting operation)

Another model is equipped with rotation stop pins so that the piston can not rotate. This requires some extra height so total height is then 66 mm. This module HA-1SR1 is shown in the photo.
