Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30U
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30U is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 30mm 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 MI8X30U
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles light-duty positioning. The Ø8 mm bore uses an M5x0.8 air port and a 4 mm piston rod with an M4x0.7 male thread. Its riveted round body and stainless construction shrug off mild corrosion, giving a real edge over painted alternatives in damp or washdown settings. The U back cover provides a 90-degree port orientation for tight spatial constraints.
For practical sizing, plan for roughly 15 N of usable work at 0.5 MPa, which safely lifts about 1.3 kg vertically with a 2:1 margin. Fixed TPU bumper pads absorb the stroke-end impact. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG sensors; choose the -S variant if position feedback is required.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30U Is Used
Micro-Clamp Actuation
Drives small electronic component clamps on PCB assembly lines, utilising the 25.1 N push force for delicate, low-mass holding.
Lab Dispenser Routing
Shifts lightweight fluid nozzle guides in laboratory automation equipment, where the stainless body withstands occasional chemical splashes.
Small Part Ejection
Pushes tiny moulded plastic parts out of testing fixtures, using the 30 mm stroke and 90-degree U cover to fit inside dense machine frames.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30U the Right Cylinder?
When sizing this 8 mm bore, there is no smaller option in the MI family, so if the 25.1 N push at 0.5 MPa is insufficient, step up to the Ø10 bore which provides 39.3 N. The 30 mm stroke is well within the 150 mm maximum standard stroke, keeping the rod rigid. The U-type rear cover mounts at 90 degrees, fitting neatly into compact assemblies.
Remember that a plain cylinder drifts if air pressure drops or the valve is centred, as the TPU bumpers only decelerate the end of travel rather than locking the load. To suspend a vertical weight safely, fit an external rod lock or a pilot-operated check valve.
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 MI8X30U FAQ
The Ø8 mm bore features an M5x0.8 port. It generates 25.1 N push and 18.8 N pull at 0.5 MPa, or 35.2 N push and 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet, so CMSG, DMSG or EMSG switches cannot be used. You must select the -S magnet variant for position sensing. It uses the ISO 6432 mounting interface and fixed TPU bumper pads.
