Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400CA 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 MI16X400CA
Generating 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 a compact riveted build. The stainless barrel and Ø6 mm rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Because the bore is Ø16, it drops directly into standard ISO 6432 mini-cylinder brackets and clevises without redesigning your footprint.
Fixed TPU bumper pads absorb the impact at stroke extremes, though they decelerate rather than provide adjustable cushioning. Plan for roughly 60 N of actual work at 0.5 MPa, which translates to lifting about 5.1 kg vertically with a safe 2:1 margin. This specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG reed switches; add an -S variant if your cycle requires position sensing.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400CA Is Used
Diverting Gate Actuation
Drives a lightweight routing flap on a packaging conveyor, using the 400 mm stroke to reach across the belt and the stainless body to survive humid packing areas.
Sample Tray Extraction
Extracts sample trays from laboratory testing equipment, where the 100.5 N push force easily overcomes drawer friction and the riveted round body resists chemical moisture.
Tote Push-off Mechanism
Pushes empty totes off an accumulation roller track in distribution hubs, relying on the CA clevis to pivot naturally as the 400 mm extension cycles.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400CA the Right Cylinder?
When sizing this 16 mm bore, the smaller Ø12 MI yields 56.5 N push while the larger Ø20 MI provides 157.0 N at 0.5 MPa, letting you step up if the 100.5 N rating feels tight. The CA rear pivot cover suits clevis mounting, and you can pair the body with LB foot, FA flange, SDB pivot or TC trunnion brackets. Keep in mind that venting air or centering the valve lets the piston drift freely, as the TPU pads only soften the end stops rather than locking the load—use a pilot check valve for suspension.
Pushing a 400 mm stroke on a Ø6 rod invites rod bending under heavy side loads, so guide the external payload carefully. Operating pressure spans 0.15-1.0 MPa, and the 1/8 inch port ensures adequate flow for speeds up to 800 mm/s.
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 MI16X400CA 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, and the air port is 1/8 inch.
Yes, the Ø16 bore uses the ISO 6432 mounting interface for standard clevis and bracket compatibility. However, this specific SKU lacks a magnet, so you cannot mount CMSG, DMSG or EMSG sensors without choosing the -S variant.
