About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X180SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 180 mm stroke with ease. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Because the piston carries a magnet, this -S SKU supports CMSG, DMSG and EMSG position switches. For actual work, plan for about 94 N of usable load at 0.5 MPa rather than the absolute maximum. Vertically mounted, it lifts roughly 8 kg safely with a 2:1 margin. The rear CM round end provides a clean, compact profile for tight assemblies.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X180SCM Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using its 8 kg vertical lift capacity and 180 mm travel.
Lab Sample Ejection
Ejects plastic test tubes from a washdown station, relying on the stainless rod to shrug off mild moisture.
Small Part Sorting
Actuates a deflector arm to route small electronic components, using the CMSG sensor to confirm the stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X180SCM the Right Cylinder?
When sizing this 180 mm stroke unit, the Ø16 bore below offers 100.5 N of push at 0.5 MPa, while the Ø25 bore above steps up to 245.3 N. This model fits standard brackets and clevises via its ISO 6432 mounting dimensions. The CM round back cover dictates the rear port orientation, so verify your layout matches this style. For a 180 mm extension, watch out for side loads; keep the rod guided to prevent bending. Remember that venting the air or centering the valve causes the piston to drift, as the TPU pads only decelerate the end of travel and do not act as a brake. To suspend a load securely, install an external rod lock or a pilot check valve.
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 MI20X180SCM 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 piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not function as a locking brake. You must add an external rod lock or pilot check valve to hold a vertical load.
