Airtac MI16-20 Stainless Steel Mini Cylinder MI16X190SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X190SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 190mm 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 MI16X190SU
Generating 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles a 190 mm travel distance. The Ø16 bore uses a 1/8 inch port and a Ø6 mm piston rod. Because the stainless barrel and rod resist mild corrosion and washdown, it outlasts painted-steel alternatives in damp or food-industry spots. The -S suffix means a piston magnet is built in, allowing you to mount CMSG, DMSG or EMSG sensors for position detection.
Plan for roughly 60 N of actual work at 0.5 MPa, which is about 60% of the theoretical rating. This translates to safely lifting a 5.1 kg part vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb the impact at the stroke ends, and the riveted round body keeps the unit compact.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X190SU Is Used
Diverter Gate Actuation
Pushes lightweight sorting flaps on packaging lines, utilising the 100.5 N push force to redirect cartons without stalling.
Lab Sample Ejection
Ejects processed sample trays with a 190 mm travel distance, where the stainless build resists chemical cleaning agents.
Vertical Part Lifting
Raises 5 kg electronic housings between conveyor tiers, relying on the built-in magnet for DMSG sensor feedback.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X190SU the Right Cylinder?
When sizing this 190 mm stroke actuator, compare it against its neighbours: the smaller Ø12 bore provides 56.5 N of push at 0.5 MPa, while the larger Ø20 bore offers 157.0 N at the same pressure. If your machine loses air or the valve is centred, the piston will drift, as the TPU pads only decelerate the stroke end rather than locking the load; add an external rod lock or pilot check valve if you need strict position holding.
This SKU features a U back cover for 90-degree mounting orientation. The long 190 mm stroke requires careful alignment to prevent rod bending and side-load wear. You can also utilise standard ISO 6432 mounting dimensions to fit readily available mini-cylinder brackets and clevises.
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 MI16X190SU FAQ
At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 120.9 N pull. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The air port is 1/8 inch.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The U back cover provides a 90-degree mounting interface for pivot applications.
