About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X90SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 90 mm stroke with an 8 mm piston rod. The 1/8" port and M8x1.25 male rod thread ensure straightforward integration. Its stainless barrel and rod resist mild corrosion, offering a real advantage over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb stroke-end impact, while the U-type back cover provides a 90-degree port orientation for tight layouts.
Because the piston carries a magnet (-S), you can mount CMSG, DMSG or EMSG switches for position sensing. 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 unit conforms to ISO 6432 mounting dimensions for bores Ø8-Ø25, dropping directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X90SU Is Used
Package Diverter
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, with the U cover keeping the 1/8" port orientation compact against the frame.
Textile Loom Guide
Shifts a yarn guide through a 90 mm travel path, relying on the stainless build to endure humid textile manufacturing environments.
Bin Gate Actuator
Opens and closes small gravity-feed hopper gates for plastic granules, lifting roughly 8 kg of material mass safely at 0.5 MPa.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X90SU the Right Cylinder?
When sizing this 20 mm bore, compare it against its neighbours: the smaller Ø16 yields 100.5 N push at 0.5 MPa, whereas the larger Ø25 provides 245.3 N. If your payload exceeds the 8 kg vertical lift capacity, step up to the Ø25. Remember that a standard cylinder drifts when air is lost or the valve centres, as the fixed bumpers only decelerate the stroke end rather than locking the rod. For suspended loads, specify an external rod lock or pilot check valve. The 90 mm stroke is well within the 500 mm maximum, but always guard against side loads to prevent rod bending.
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 MI20X90SU FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port size is 1/8".
Yes, the -S suffix means it has a built-in piston magnet for CMSG, DMSG or EMSG switches. The U-type back cover provides a 90-degree port orientation, and the body uses standard ISO 6432 mounting dimensions for easy bracket fitting.
