Airtac MI16-20 Stainless Steel Mini Cylinder MI16X220SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X220SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 220mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X220SU
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 220 mm stroke with ease. The Ø16 mm bore uses a 1/8" port and a Ø6 mm piston rod with an M6x1.0 male thread. Its riveted stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The built-in magnet (-S) directly supports CMSG, DMSG and EMSG reed or electronic switches for position sensing.
For practical sizing, plan for about 60 N of real work at 0.5 MPa rather than the absolute maximum. This equates to lifting roughly 5.1 kg vertically with a safe 2:1 margin. Fixed TPU bumper pads absorb the impact at stroke extremes to protect the mechanism, and the U-type back cover provides a 90-degree port orientation for tight machinery layouts.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X220SU Is Used
Package Diverting Gate
Actuates a lightweight routing flap on a packaging conveyor, using the 100.5 N push force to redirect small cardboard cartons at high speed.
Lab Sample Ejection
Ejects processed fluid samples from a testing carousel, where the stainless steel construction resists chemical mist and the 220 mm stroke clears the work area.
Bin Lid Automation
Pivots a 90-degree hinged cover on a sorting bin, lifting approximately 5 kg of lid weight with a safe 2:1 mechanical margin at 0.5 MPa.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X220SU the Right Cylinder?
When sizing this 16 mm bore, the smaller Ø12 option yields 56.5 N push at 0.5 MPa, while stepping up to the Ø20 bore provides 157.0 N. This model includes the -S magnet for position feedback and the U back cover for a 90-degree mounting approach; you can also utilise LB foot, FA flange, SDB pivot or TC trunnion brackets. Because the 220 mm stroke is relatively long for a mini cylinder, carefully manage side loads to prevent rod bending and premature seal wear.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centred. The fixed TPU pads only decelerate the piston near the end of travel and do not function as a locking brake. To suspend a load safely during an emergency stop or air loss, fit an external rod lock or install a pilot-operated check valve in the air lines.
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 MI16X220SU FAQ
The Ø16 mm bore features a 1/8" air port. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, increasing to 140.7 N push and 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG switches for precise position detection. Additionally, the Ø16 mm dimension adheres to the ISO 6432 mini-cylinder mounting interface, ensuring it drops directly into standard clevises and brackets.
