Airtac MI16-20 Stainless Steel Mini Cylinder MI16X225SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X225SCM is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 225mm 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 MI16X225SCM
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 225 mm stroke with ease. The Ø16 mm bore uses a 1/8" port and a Ø6 mm piston rod with an M6x1.0 male thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Because it includes a piston magnet, this unit supports CMSG, DMSG and EMSG switches for position sensing. The CM round end rear cover provides a clean back profile for tight assemblies. Plan for roughly 60 N of actual work at 0.5 MPa, which means it lifts about 5.1 kg vertically with a 2:1 safety margin. The ISO 6432 mounting interface ensures it drops straight into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X225SCM Is Used
Package Sorting Diverter
Pushes lightweight cardboard cartons on a packaging line using its 100.5 N push force, while the stainless body handles occasional moisture washdowns.
Textile Loom Tensioner
Moves a 225 mm stroke to position thread guides, relying on the CM round end cover to fit neatly within the compact machinery frame.
Lab Sample Ejection
Ejects processed vials from a testing carousel, using the built-in magnet and a DMSG sensor to confirm full extension before the next cycle.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X225SCM the Right Cylinder?
When sizing this actuator, the Ø12 mm bore below provides 56.5 N push at 0.5 MPa, while the Ø20 mm bore above steps up to 157.0 N. This 16 mm option sits perfectly in the middle for medium-duty sorting tasks. The 225 mm stroke is well within the 500 mm maximum standard stroke, but at this length you should carefully manage side loads to prevent rod bending and premature seal wear. The LB foot, FA flange, SDB pivot and TC trunnion mounts fit standard ISO 6432 dimensions.
Remember that a plain double-acting cylinder drifts when air is removed or the valve is centered; the TPU bumpers only decelerate the stroke end and do not function as a brake. To suspend a load safely during a pressure drop, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MI16X225SCM 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".
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the rod near the stroke end and do not act as a lock. You must use an external rod lock or pilot check valve to hold a suspended load.
