Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SCM is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 400mm 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 MI16X400SCM
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles long 400 mm strokes with ease. The Ø16 mm bore uses a 1/8 inch port and a Ø6 mm piston rod with an M6x1.0 male thread. Its stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp or washdown environments.
Featuring a CM round end cover and fixed TPU bumper pads that decelerate the stroke end without adjustable cushioning, it operates at 30-800 mm/s. Because it includes a piston magnet (-S), you can mount CMSG, DMSG or EMSG sensors for position detection. 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.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SCM Is Used
Diverting Gate Actuation
Pushes light routing flaps on packaging lines using its 100.5 N thrust, while the stainless build survives humid washdown zones.
Long-Reach Carton Pusher
Uses the full 400 mm stroke to index small cardboard boxes between conveyor lanes without needing a larger profile cylinder.
Sample Tube Ejection
Extends 400 mm to eject filled test tubes from a diagnostic carousel, relying on the -S magnet to trigger a DMSG reed sensor.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SCM the Right Cylinder?
This 16 mm bore sits between the smaller MI12 (56.5 N push at 0.5 MPa) and the larger MI20 (157.0 N push at 0.5 MPa), giving you a clear upgrade path if your air pressure fluctuates. The 400 mm stroke is well within the 500 mm maximum for this bore, but at full extension you must minimize side loading to prevent rod bending. The ISO 6432 mounting interface lets you drop this cylinder straight into standard mini-cylinder brackets, foot mounts (LB), flanges (FA) or TC trunnions.
Remember that a standard double-acting cylinder drifts when air is removed or the valve is centered, as the TPU bumpers only soften end impacts and act as neither a lock nor a brake. To suspend a load safely mid-stroke, pair this unit with an external rod lock or a pilot-operated check valve.
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 MI16X400SCM FAQ
This 16 mm bore cylinder features a 1/8 inch port and generates 100.5 N push / 86.4 N pull at 0.5 MPa, and 140.7 N push / 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
Yes, it conforms to ISO 6432 mounting dimensions for easy bracket fitting, and the included -S magnet supports CMSG, DMSG and EMSG switches. The rear CM round end cover also provides flexible port and mounting orientation.
