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 is standard because of the powerful return spring, but the actuator can also used in a double acting mode.

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