Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40SCM is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 40mm 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 MI16X40SCM
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation tasks with ease. The riveted barrel and piston rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Because the bore is Ø16, it conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for easy design integration.
This specific SKU includes a built-in piston magnet for position sensing and features a CM round end cover. Plan for roughly 60 N of actual work at 0.5 MPa, which means it lifts about 5.1 kg vertically with a safe 2:1 margin. Air connects via a 1/8 inch port, and fixed TPU bumper pads absorb the impact at stroke ends without needing manual adjustment.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40SCM Is Used
Small Parts Ejection
Pushes lightweight plastic or aluminum parts out of a CNC machining enclosure using a 100.5 N extend force, relying on the stainless rod to resist coolant mist.
Flap Folding
Actuates a cardboard flap-folding arm on a compact packaging line, where the 40 mm stroke and CM round end fit neatly into tight transfer spaces.
Lab Sample Diverting
Diverts small fluid vials on a diagnostic analyzer, using the built-in magnet with a DMSG sensor to confirm the extend position before filling.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40SCM the Right Cylinder?
When sizing this 16 mm bore, compare it against its neighbors: a 12 mm bore yields 56.5 N push, while a 20 mm bore provides 157.0 N at 0.5 MPa. If your application loses air or the valve centers, the piston will drift and drop the load, as the TPU pads only soften the end-of-stroke impact rather than locking the rod. To hold a vertical position securely, add an external rod lock or a pilot-operated check valve.
The included magnet allows CMSG, DMSG, or EMSG switches to track position. You can mount this unit using LB foot, FA flange, SDB pivot, or TC trunnion hardware, while the CM round end cover dictates the rear port and mounting orientation. At a 40 mm stroke, side-load stress on the 6 mm rod is minimal, but always ensure the load moves linearly to prevent premature seal wear.
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 MI16X40SCM FAQ
At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 120.9 N pull. The theoretical maximum force is 20.5 kgf at 1.0 MPa. The air port size is 1/8 inch.
No, the base MI uses fixed TPU bumper pads that decelerate the stroke end without manual adjustment. If you need an adjustable air cushion for higher speeds, look at the MIC variant. This model also includes a magnet for CMSG, DMSG, or EMSG sensors.
