Airtac MI16-20 Stainless Steel Mini Cylinder MI20X220SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X220SU is a genuine double acting round-body mini air cylinder with a Ø20mm 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 MI20X220SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles mid-range automation tasks with ease. The Ø20 mm bore uses a 1/8 inch air port and an M8x1.25 male rod thread. Its riveted round body relies on fixed TPU bumper pads to decelerate the piston at stroke ends, while the built-in magnet (-S) supports CMSG, DMSG, or EMSG sensors for position detection.
The stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. Because it yields about 94 N of usable work at 0.5 MPa, you can expect it to lift roughly 8 kg vertically with a 2:1 safety margin. The rear U cover provides a 90-degree mounting orientation, and the standard 220 mm stroke stays well within the 500 mm maximum for this bore.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X220SU Is Used
Package Diverter
Pushes light cardboard cartons on a packaging line using its 157 N push force and 220 mm stroke to clear the belt path.
Textile Loom Guide
Shifts a yarn guide arm across the loom width, relying on the stainless build to endure humid manufacturing conditions.
Bin Lid Actuator
Opens and closes elevated hopper lids on storage bins, taking advantage of the 90-degree U cover for tight frame clearances.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X220SU the Right Cylinder?
When sizing this unit, consider the neighbouring bores: the smaller Ø16 generates 100.5 N of push at 0.5 MPa, whereas the larger Ø25 provides 245.3 N. If your application loses air pressure or the valve is centred, the piston will drift, as the TPU bumpers only soften the end-of-stroke impact rather than locking the rod. To maintain vertical loads securely, integrate an external rod lock or a pilot-operated check valve.
The 220 mm stroke on the Ø8 mm rod is well within the 500 mm limit, but long strokes naturally invite rod bending under side loads. Ensure correct alignment to prevent premature seal wear. This SKU includes the -S magnet for electronic or reed switches, and the U back cover simplifies compact 90-degree installations.
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 MI20X220SU FAQ
This Ø20 mm bore cylinder features a 1/8 inch air port. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
No, the piston will drift if air pressure drops or the valve is centred. The fixed TPU bumpers only decelerate the stroke end and do not act as a brake. Use an external rod lock or pilot check valve for load holding.
