Frequently Asked Questions
What is the SMC MHZ2-16D?
It is a standard two-finger parallel pneumatic air gripper in the SMC MHZ2 series, featuring a 16 mm bore, double-acting operation and a 6 mm total opening and closing stroke.
Is the MHZ2-16D single-acting or double-acting?
It is double-acting. Compressed air is used to open and close the gripper fingers, rather than relying on a return spring.
What is the bore size?
The MHZ2-16D has a 16 mm pneumatic bore.
What is the total finger stroke?
The total opening and closing stroke is 6 mm for both fingers, corresponding to approximately 3 mm of travel per finger.
What gripping force does the MHZ2-16D provide?
The SMC catalog lists reference effective gripping forces of 34 N per finger for external gripping and 45 N per finger for internal gripping. These are not guaranteed forces at every pressure or gripping point.
What air pressure is required?
The specified operating pressure range is 0.1 to 0.7 MPa, equivalent to 1 to 7 bar or approximately 15 to 102 psi.
What pneumatic connection size does it use?
The gripper uses M5 × 0.8 pneumatic ports. Select fittings and tubing to suit the pneumatic system.
What is the maximum operating frequency?
The manufacturer specifies a maximum operating frequency of 180 cycles per minute for this model size. Actual operating speed depends on load, pressure, tubing and flow control settings.
What is the positioning repeatability?
The specified repeatability is ±0.01 mm under manufacturer test conditions. Actual gripping accuracy also depends on the workpiece, finger attachments and machine setup.
Does the MHZ2-16D come with an auto switch?
No. The basic MHZ2-16D designation does not specify an included auto switch. Versions with switch suffixes are available, and compatible switches can be selected separately.
Does the MHZ2-16D require lubrication?
No. SMC specifies non-lubricated operation for the standard MHZ2 series. Use appropriately prepared compressed air and follow the manufacturer's maintenance instructions.
What should be checked before ordering?
Confirm the complete model MHZ2-16D, 16 mm bore, double-acting design, 6 mm total stroke, 0.1 to 0.7 MPa operating pressure, M5 pneumatic ports, required gripping force, finger attachment dimensions, mounting configuration and whether position switches or other accessories are needed.
