Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150CM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150CM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 150mm 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 MI20X150CM
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 150 mm stroke with a CM round end cover. The riveted stainless barrel and Ø8 mm rod naturally resist mild corrosion, giving it a real edge over painted alternatives in damp production areas. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the piston smoothly without the complexity of adjustable cushioning.
For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which translates to lifting an 8 kg part vertically with a safe 2:1 margin. Because this Ø20 bore uses standard ISO 6432 mounting dimensions, it drops directly into common mini-cylinder brackets and clevises. Air connects via a 1/8 inch port, and the unit operates efficiently between 30 and 800 mm/s.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150CM Is Used
Packaging Diverter
Pushes light cardboard cartons at 157 N on a packaging line, utilizing the 150 mm stroke to shift products cleanly between parallel conveyor belts.
Lab Sample Ejector
Ejects plastic sample trays from a testing station, where the stainless steel construction withstands occasional chemical splashes and wipe-downs.
Component Sorter
Separates small aluminum brackets into designated chutes, relying on the 131.9 N pull force at 0.5 MPa to retract the diverter arm reliably.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150CM the Right Cylinder?
When sizing this actuator, the Ø16 bore below provides 100.5 N of push at 0.5 MPa, while the Ø25 above steps up to 245.3 N, letting you fine-tune force to the exact load. The 150 mm stroke is well within the 500 mm maximum standard stroke limit, keeping the unit readily available. Keep in mind that a plain double-acting cylinder like this will drift if air pressure is lost or the valve is centered, as the TPU pads only soften the end of stroke rather than locking the rod; add a pilot-operated check valve if you need to suspend a load safely. Since this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches—order the -S variant if your control system requires sensor feedback.
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 MI20X150CM FAQ
This double-acting cylinder delivers 157 N push and 131.9 N pull at 0.5 MPa, increasing to 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa. It features a 1/8 inch air port and an Ø8 mm piston rod with an M8x1.25 male thread.
Yes, the Ø20 bore conforms to ISO 6432 mounting dimensions, so it fits standard mini-cylinder clevises and foot mounts. However, because this specific SKU lacks the internal magnet, it cannot host CMSG, DMSG, or EMSG switches; you must specify the -S option for position sensing.
