Low profile air gripper with space-saving design

Height is approximately 1/3 the size of ■The low profile design saves space and reduces bending ■ improved accuracy with smooth • Reduced bending moment and vibration Stroke selection is available. 3 standard stroke lengths are available for each bore size. Stroke can be selected to suit the workpiece.

Low Profile Air Gripper Seríes MHF2 Note 1) This is the value when no offset load is applied to the finger. When an offset load is applied to the finger, the maximum value is ±0.15 mm due to the influence of backlash of the rack and pinion. Note 2) Refer to pages 761 to 809 for further information on auto switches. Note 1) At the pressure of 0.5 MPa, when gripping point L is 20 mm.
