Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400U 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 MI16X400U
Generating about 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles long 400 mm strokes with a compact round-body build. The riveted stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because the bore is Ø16, it uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises for easy design integration.
With a 100.5 N push rating at 0.5 MPa, plan for roughly 60 N of actual work to keep a safe margin. Vertically, that same 0.5 MPa thrust equals about 5.1 kg of lifting force, so you can match it confidently to real part weights. The U-type back cover provides a 90-degree port orientation for tight routing. This base SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to the magnetized variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400U Is Used
Carton Push-off Diverter
Uses the 100.5 N push at 0.5 MPa to deflect light cardboard cartons from a main packaging line onto a secondary belt over the 400 mm travel.
Pallet Tag Applicator
Extends 400 mm to press identification labels onto the side of incoming pallets, relying on the stainless rod to resist humid dock environments.
Component Ejector Station
Pushes finished aluminum brackets out of a machining fixture, using the U-type 90-degree rear cover to keep the 1/8 inch air line neatly routed away from the tool.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400U the Right Cylinder?
When sizing this 16 mm bore, the smaller Ø12 generates 56.5 N push at 0.5 MPa, while stepping up to the Ø20 yields 157.0 N, giving you clear scaling if the 100.5 N output is too tight or excessive. The 400 mm stroke is well within the 500 mm maximum standard stroke for this bore, though at full extension you should watch for rod-bending side loads. The fixed TPU bumper pads decelerate the stroke end but do not act as an adjustable air cushion; for high-speed energy absorption, look at the MIC variant.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered, as the bumpers only soften impact rather than locking the rod. To hold a vertical load securely in place, add an external rod lock or a pilot-operated check valve to your 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 MI16X400U 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 is 1/8 inch and the male rod thread is M6x1.0.
No, this specific SKU does not include the -S magnet, so it cannot host CMSG, DMSG or EMSG magnetic switches. You must select the -S variant for sensing capabilities. It uses the ISO 6432 mounting interface and features fixed TPU bumper pads rather than an adjustable air cushion.
