Airtac MI16-20 Stainless Steel Mini Cylinder MI20X15SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X15SCM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 15mm 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 MI20X15SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 15 mm strokes with precision. The riveted stainless barrel and rod shrug off mild corrosion, making it superior to painted alternatives in damp washdown environments. Because the bore is Ø20, it conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for easy design integration.
Equipped with a built-in magnet, this variant supports CMSG, DMSG and EMSG position switches. Plan for roughly 94 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting about 8 kg vertically. The 1/8 inch port supplies air efficiently, while fixed TPU bumper pads absorb the impact at stroke end.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X15SCM Is Used
Ejector Gate Diverter
Rapidly flips a lightweight plastic diverter flap on a packaging line using 157 N of push force over a tight 15 mm travel distance.
Small Part Stopper
Acts as a pneumatic stop pin for small electronic components on a conveyor, with the stainless build resisting factory humidity.
Clamp Actuator
Secures thin sheet metal during a quick stamping operation, utilizing the built-in magnet to confirm the clamp is fully extended.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X15SCM the Right Cylinder?
When sizing this actuator, the neighbouring Ø16 bore offers 100.5 N push at 0.5 MPa, whereas stepping up to the Ø25 bore yields 245.3 N. This Ø20 model fits neatly in the middle for compact tasks needing around 157 N. The CM round end cover provides a specific rear profile for your mounting layout, complementing available LB foot, FA flange and TC trunnion options.
Remember that a standard pneumatic cylinder drifts when air pressure is lost or the valve is centred, as the TPU bumpers only soften the stroke end rather than locking the rod. To suspend a load securely, install an external rod lock or a pilot-operated check valve. The extremely short 15 mm stroke also minimizes rod-bending side loads.
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 MI20X15SCM 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, and the air port size is 1/8 inch.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. For vertical load holding, you must use an external rod lock or a pilot-operated check valve.
