Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20CM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20CM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 20mm 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 MI20X20CM
Delivering 157 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles compact automation with ease. The stainless-steel barrel and rod shrug off mild corrosion, making it superior to painted alternatives in damp or washdown environments. Its riveted construction keeps the unit light, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Equipped with a 1/8" port and an M8x1.25 male rod thread, the Ø20 bore uses standard ISO 6432 mounting dimensions to drop directly into common mini-cylinder brackets. For practical sizing, plan for a safe working load of about 94 N, which easily lifts an 8 kg part vertically with a 2:1 safety margin. Note this specific CM round-end configuration lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without upgrading to an -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20CM Is Used
Product Diverting Gate
Snaps a short 20 mm stroke to flick lightweight cardboard cartons on a packaging line, utilizing the 157 N push force reliably.
Lab Sample Ejector
Ejects plastic test tubes from a wet processing station, leveraging the stainless steel rod for mild corrosion resistance.
Small Part Clamp
Secures aluminium brackets during a light machining pass, taking advantage of the 131.9 N pull force for a firm grip.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20CM the Right Cylinder?
When sizing this 20 mm bore, compare your actual load against the 131.9 N pull force at 0.5 MPa. If your application requires less power, the neighbouring Ø16 generates 100.5 N of push; if you need more muscle, stepping up to the Ø25 yields 245.3 N. The 20 mm stroke is very short, which minimizes rod bending and side-load risks, but remember that this plain cylinder will drift if air pressure drops. The TPU bumpers only decelerate the end of travel rather than locking the load, so add an external rod lock or pilot check valve if you need strict position holding.
This CM round-end model arrives without a magnet, meaning direct switch mounting is impossible. If your workflow requires position feedback, select the -S magnet version to enable CMSG, DMSG or EMSG sensors. You can pair it with LB foot, FA flange, SDB pivot or TC trunnion hardware to fit your frame.
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 MI20X20CM 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 of 32 kgf at 1.0 MPa.
No, this specific SKU lacks a magnet and cannot accept CMSG, DMSG or EMSG switches. You must select an -S variant for sensor compatibility. The unit relies on fixed TPU bumper pads for end-of-stroke deceleration and conforms to ISO 6432 mounting dimensions.
