Airtac MI16-20 Stainless Steel Mini Cylinder MI20X105CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X105CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 105mm 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 MI20X105CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles 105 mm of travel with a CA pivot clevis. The rolled stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its ISO 6432 mounting interface drops directly into standard mini-cylinder brackets.
Fixed TPU bumper pads absorb the impact at stroke extremes, though they decelerate rather than cushion adjustably. Because this SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG sensors. For actual work at 0.5 MPa, plan for about 94 N of usable load, which equates to lifting roughly 8 kg vertically with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X105CA Is Used
Diverter Gate Actuation
Pushes light routing flaps on packaging lines using its 157 N thrust, with the stainless build surviving humid washdown environments.
Small Press Ejection
Uses the 105 mm stroke and CA pivot clevis to kick stamped small parts out of a die, relying on the fixed TPU pads to absorb the end impact.
Carton Flap Folding
Folds corrugated cardboard flaps prior to sealing, where the 8 kg vertical lift capacity easily manages light packaging materials.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X105CA the Right Cylinder?
When sizing this 20 mm bore, the smaller 16 mm option yields 100.5 N push at 0.5 MPa, while the larger 25 mm bore provides 245.3 N, letting you step up if the load drifts. The 1/8" port and M8x1.25 male rod thread are fixed by the bore size. With a 105 mm stroke, keep side-load forces minimal to avoid bending the 8 mm rod.
The CA rear pivot cover suits articulated rod-end connections, but a plain MI will drift and drop its load if air pressure is lost or the valve is centered. The fixed bumpers only soften the end-of-stroke impact, so fit an external rod lock or pilot check valve if you need to hold a vertical load securely in place.
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 MI20X105CA FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum force of 32 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet required for switches. You must select the -S variant (MI20X105CA-S) to use CMSG, DMSG or EMSG magnetic sensors. The unit uses an ISO 6432 mounting interface and a CA pivot clevis for installation.
