Operating pressure (MPa)
Unit: N
Note 1) Refer to Rotary Angle figure.
Note 2) Direction of rotation viewed from the rod end when the piston rod is retracting
Note 3) Clamp force at 0.5 MPa
Note 4) When using the cylinder within a pressure range from 0.61 to 1 MPa, please use –X2071.
Note 5) Be sure to install a speed controller to the cylinder, and adjust the cylinder speed to make it within the
range from 50 to 200 mm/s. To adjust the speed, start with the needle in the completely closed position,
and then adjust it by opening gradually.
