About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X16SU
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact 16 mm strokes with ease. Its 1/8" port and M6x1.0 male rod thread provide a robust pneumatic connection for tight machinery. The -S suffix indicates a built-in piston magnet, enabling direct mounting of CMSG, DMSG or EMSG reed and electronic switches for precise position sensing.
The riveted stainless barrel and rod resist mild corrosion, outlasting painted alternatives in damp or washdown settings. Because it conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. Plan for roughly 60 N of actual work at 0.5 MPa, which translates to lifting about 5.1 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X16SU Is Used
PCB Ejector Pins
Cycles a 5 kg board stack out of a test fixture using the 100.5 N push force, relying on the 16 mm stroke for a rapid, compact ejection.
Carton Flap Tucking
Tucks small cardboard flaps on a packaging line where the stainless body withstands occasional washdowns and the U cover fits the 90-degree mount.
Small Part Sorting Gate
Diverts lightweight plastic components on a conveyor, using the built-in magnet and a DMSG sensor to confirm the 16 mm shift in milliseconds.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X16SU the Right Cylinder?
If 100.5 N is excessive, step down to the Ø12 bore which yields 56.5 N at 0.5 MPa; if more thrust is required, the Ø20 bore provides 157.0 N. This 16 mm stroke is highly compact, minimizing rod bending and side-load risks even under dynamic cycling. The U back cover configures the port and pivot at 90 degrees for tight spatial constraints.
Note that venting air or centering the valve causes the piston to drift, as the fixed TPU bumper pads only decelerate the stroke end rather than locking the load. To prevent vertical dropping, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MI16-20 Stainless Steel Mini Cylinder MI16X16SU FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N. At 0.7 MPa it pushes 140.7 N and pulls 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M6x1.0.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only soften the stroke end and do not act as a brake. You must add an external rod lock or pilot check valve to hold a suspended load.
