Airtac MI8~12 Stainless Steel Mini Cylinder MI12X32SU
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X32SU is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 32mm 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 MI12X32SU
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles light actuation with precision. The riveted barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. Because it includes a piston magnet (-S), you can mount CMSG, DMSG or EMSG switches for position sensing. The U back cover provides a 90-degree port orientation, simplifying hose routing in tight machinery.
Plan for about 34 N of actual work at 0.5 MPa, which safely lifts roughly 2.9 kg vertically with a 2:1 margin. Fixed TPU bumper pads absorb the stroke-end impact, and the M5x0.8 port matches standard miniature pneumatic fittings.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X32SU Is Used
PCB Component Placement
Actuates a delicate pick-and-place head for electronic assembly, using the 56.5 N push force to seat through-hole connectors without damaging the board.
Carton Flap Folding
Folds small cardboard flaps on a packaging line, where the stainless body withstands humid washdown conditions during facility cleaning.
Lab Dispenser Actuation
Drives a precision fluid dispensing valve, relying on the 90-degree U cover to keep pneumatic tubing neatly tucked inside the laboratory cabinet.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X32SU the Right Cylinder?
When sizing this 12 mm bore, compare it against the smaller MI8X32SU (25.1 N push @0.5 MPa) or the larger MI16X32SU (100.5 N push @0.5 MPa) to match your exact force requirements. The ISO 6432 mounting interface lets you drop this cylinder directly into standard mini-cylinder brackets and clevises. For position feedback, the internal magnet pairs directly with CMSG, DMSG or EMSG sensors.
Remember that a plain cylinder drifts when air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a brake. To hold a load vertically, add 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 MI12X32SU FAQ
At 0.5 MPa it provides 56.5 N push and 42.4 N pull. At 0.7 MPa it provides 79.1 N push and 59.4 N pull. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port size is M5x0.8.
No, the base MI uses fixed TPU bumper pads that decelerate the stroke end but are not an adjustable air cushion; for adjustable cushioning, look at the MIC variant. This model includes a magnet (-S) for CMSG, DMSG or EMSG sensors.
