Airtac MI8~12 Stainless Steel Mini Cylinder MI12X40UTC
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X40UTC is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 40mm 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 MI12X40UTC
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles light-duty positioning with ease. The Ø12 mm bore features an M5x0.8 port and a Ø6 mm piston rod. Because the barrel and rod resist mild corrosion, the riveted construction outlasts painted alternatives in damp production areas. Its dimensions follow the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises.
Fixed TPU bumper pads absorb impact at the stroke ends, though they do not provide adjustable cushioning. Plan for a safe working load of roughly 34 N, which lets you lift about 2.9 kg vertically with a 2:1 safety margin. This specific configuration includes a U-type 90-degree rear cover and ships without a magnet, meaning it cannot host CMSG, DMSG or EMSG sensors unless upgraded to an -S variant.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X40UTC Is Used
Electronic Component Handling
Indexes delicate PCBs on a pick-and-place line using the 56.5 N push force, while the stainless build resists flux fumes.
Packaging Diverter
Pushes small cardboard cartons off a belt using the 40 mm stroke, with the TC trunnion absorbing lateral pivot stress.
Lab Sample Ejector
Ejects filled test tube racks from a dispensing station, lifting roughly 2.9 kg safely within a 2:1 vertical margin.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X40UTC the Right Cylinder?
When sizing this 12 mm bore, the smaller Ø8 option provides 25.1 N of push force, while the larger Ø16 offers 100.5 N at 0.5 MPa. Choose this model for loads requiring around 34 N of actual work. The included TC trunnion mount pairs well with the U 90-degree back cover for pivoting articulation. Since this SKU lacks the -S magnet, position sensing is unavailable. If your mechanism drops air pressure or the valve centers, the piston will drift; the bumpers only decelerate the end of travel rather than locking the rod. For suspended loads, 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 MI12X40UTC FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N. At 0.7 MPa it pushes 79.1 N and pulls 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port is M5x0.8.
No, this specific SKU lacks a piston magnet, so CMSG, DMSG or EMSG switches will not function. You must select an -S variant for sensor compatibility. It uses a U 90-degree back cover and TC trunnion mounting.
