Airtac MI16-20 Stainless Steel Mini Cylinder MI20X120U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X120U is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 120mm 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 MI20X120U
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles a 120 mm stroke with a 1/8" air port. The riveted round body uses a stainless barrel and rod to resist mild corrosion, giving it a real edge over painted alternatives in damp production areas. Its dimensions follow the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises.
Because the bumper pads only decelerate the stroke end, plan for roughly 94 N of actual work at 0.5 MPa to maintain safe margins. This translates to lifting about 8 kg vertically, making it suitable for moderate component transfer tasks. The rear U cover provides a 90-degree mounting orientation, and since this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X120U Is Used
Packaging Diverter
Pushes light cardboard cartons at 157 N onto an adjacent conveyor belt using the 90-degree U cover to keep air lines neatly tucked away.
Lab Sample Ejector
Ejects filled test tube racks from a processing station, leveraging the stainless steel construction to withstand humid laboratory environments.
Parts Ejector
Kicks machined aluminum brackets out of a CNC fixture, safely moving parts weighing up to 8 kg vertically during unloading.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X120U the Right Cylinder?
When sizing this 20 mm bore, the smaller 16 mm option provides 100.5 N of push at 0.5 MPa, while stepping up to the 25 mm bore yields 245.3 N, giving you clear force scaling for your fixture. This model features the U back cover for 90-degree port entry, and because it lacks a magnet, you must choose an -S variant if your application requires CMSG, DMSG or EMSG sensors. The 120 mm stroke is well within the 500 mm maximum, though at this length you should ensure rigid front mounting to prevent rod bending under side loads. Remember that venting the air supply causes the piston to drift, as the fixed TPU bumpers only soften impact rather than locking the rod; use a pilot check valve to hold a suspended load.
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 MI20X120U FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it delivers 219.8 N push and 184.7 N pull, with a theoretical maximum of 32 kgf at 1.0 MPa. The air port size is 1/8".
No, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches will not function. You must select the -S variant to enable position sensing.
