About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X110SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 110 mm stroke with ease. The Ø20 mm bore features a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Riveted construction keeps the body compact, while fixed TPU bumper pads absorb impact at the stroke ends.
For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which translates to lifting about 8 kg vertically with a 2:1 safety margin. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing. A U-type back cover provides a 90-degree port and mounting orientation, and the body accepts standard ISO 6432 mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X110SU Is Used
Package Diverter
Pushes light cardboard cartons on a packaging line using 157 N of thrust, surviving humid washdown areas thanks to the stainless build.
Textile Loom Tensioner
Maintains thread tension via the 110 mm stroke, using the U-type back cover for a 90-degree mount in tight weaving machinery.
Lab Sample Ejector
Ejects processed sample trays with a safe 94 N working force, triggering a DMSG sensor via the internal magnet to confirm ejection.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X110SU the Right Cylinder?
When sizing this unit, note the Ø16 bore below offers 100.5 N push at 0.5 MPa, while the Ø25 above steps up to 245.3 N, giving you clear boundaries if your load shifts. Because this is a double-acting cylinder with fixed TPU bumpers, it will drift and cannot hold a load if air pressure drops or the valve is centred; add an external rod lock or pilot check valve for suspended loads. The 110 mm stroke is well within the 500 mm maximum, but at extended lengths you should minimize side-loading to prevent rod bending. This SKU includes the magnet for sensors and the U back cover, so match your mounting and detection accessories accordingly.
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 MI20X110SU FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M8x1.25.
No, the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake; the piston will drift if air is lost, so use a pilot check valve for suspended loads. It uses the ISO 6432 mounting interface and features a U-type back cover for 90-degree mounting.
