Airtac MI16-20 Stainless Steel Mini Cylinder MI20X10U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X10U is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 10mm 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 MI20X10U
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 10 mm shifts with precision. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp workcells. Its fixed TPU pads absorb end-of-stroke impact without offering adjustable cushioning.
With a 157 N push rating at 0.5 MPa, plan for roughly 94 N of actual work to keep cycles smooth. That same 0.5 MPa figure translates to lifting about 8 kg vertically with a safe 2:1 margin. The 1/8" port feeds the Ø8 mm rod, and the U-style rear cover mounts at 90 degrees for compact lateral placement. Because this SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X10U Is Used
Clamp Actuation
Provides a short 10 mm stroke to lock small machined aluminium parts in a CNC fixture, utilizing its 8 kg vertical lift capacity.
Flap Deflection
Uses the 90-degree U cover to tuck into a cardboard carton sealer, rapidly pushing guide rails for carton alignment.
Gate Diversion
Briefly extends 10 mm to pop up a diverter blade on a stainless-steel washdown conveyor, relying on the riveted body for damp resistance.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X10U the Right Cylinder?
If 157 N at 0.5 MPa is too much, step down to the Ø16 bore which provides 100.5 N; if you need more power, the Ø25 bore offers 245.3 N. The 10 mm stroke is highly compact, minimizing rod bending risks, but ensure your side-load geometry is tight. The 90-degree U back cover suits tight corner mounting, and standard ISO 6432 dimensions mean it drops right into generic mini brackets.
Remember that venting the air causes the piston to drift, as the TPU bumpers only decelerate the stroke end rather than locking the load. For vertical or suspended loads that must hold position, add an external rod lock or a pilot-operated check valve. To add position sensing, you must switch to the -S magnet variant.
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 MI20X10U FAQ
This Ø20 mm bore cylinder uses a 1/8" port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet, so CMSG, DMSG, or EMSG switches cannot be used. You would need the -S variant for sensing. It uses standard ISO 6432 mounting dimensions and fixed TPU bumper pads for stroke deceleration.
