Airtac MI8~12 Stainless Steel Mini Cylinder MI8X10SU
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X10SU is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 10mm stroke, M5×0.8 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 MI8~12 Stainless Steel Mini Cylinder MI8X10SU
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles very short 10 mm strokes with precision. The Ø8 mm bore uses an M5x0.8 port and a 4 mm piston rod. Because the 25.1 N rating is theoretical, plan for a real working load of about 15 N. Vertically, it safely lifts around 1.3 kg when you apply a 2:1 safety margin.
The riveted round-body construction yields a compact footprint that resists mild corrosion, outperforming painted alternatives in damp environments. This -S variant includes a piston magnet for CMSG, DMSG or EMSG switches. The U back cover provides a 90-degree port orientation, and fixed TPU bumper pads absorb end-of-stroke impacts without acting as an adjustable cushion.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X10SU Is Used
Micro Ejector Pins
Provides a short 10 mm kick to eject small plastic parts from an injection mould, using its 15 N safe working load effectively.
PCB Clamp Release
Actuates a tiny clamping jaw on a PCB assembly fixture, where the compact stainless body handles light washdown cycles.
Lab Dispenser Valve
Triggers a micro-dispense valve for adhesives, relying on the 90-degree U cover and CMSG sensor for precise shot timing.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X10SU the Right Cylinder?
As the smallest bore in the MI family, there is no smaller option; if you need more force, stepping up to the Ø10 bore raises push force to 39.3 N at 0.5 MPa. For this 10 mm stroke, side-load and rod-bending risks are minimal. Remember that the TPU bumpers only decelerate the stroke end; the piston will drift if air is lost, so fit an external pilot check valve if you must hold a load vertically. The ISO 6432 mounting interface ensures compatibility with standard mini-cylinder brackets.
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 MI8~12 Stainless Steel Mini Cylinder MI8X10SU FAQ
At 0.5 MPa it pushes 25.1 N and pulls 18.8 N. At 0.7 MPa it pushes 35.2 N and pulls 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa. The air port is M5x0.8.
Yes. The -S suffix means a piston magnet is installed, allowing you to mount CMSG, DMSG or EMSG switches for position detection. A SKU without the S cannot take a sensor.
