Airtac MI8~12 Stainless Steel Mini Cylinder MI12X80SU
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X80SU is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 80mm 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 MI12X80SU
Delivering 56.5 N of push force at 0.5 MPa, the AirTAC MI12X80SU is a double-acting round-body mini cylinder built for compact automation. The stainless-steel barrel and Ø6 mm piston rod shrug off mild corrosion, making it a hardier choice than painted alternatives in damp or washdown-prone areas. An 80 mm stroke gives ample travel for small parts handling, while fixed TPU bumper pads absorb the end-of-stroke impact. Because this is an -S variant, the internal piston magnet is present and ready for CMSG, DMSG or EMSG position switches.
Conforming to the ISO 6432 mounting interface for Ø12 bores, it drops directly into standard mini-cylinder brackets and clevises. The M5x0.8 air port keeps the pneumatic footprint small. For practical sizing, plan for about 34 N of real work at 0.5 MPa, which translates to lifting roughly 2.9 kg vertically with a 2:1 safety margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X80SU Is Used
Electronic Component Testing
Applies the 56.5 N push force at 0.5 MPa to actuate probe pins on PCB test fixtures, using the 80 mm stroke to clear the bed of nails during board loading.
Small Parts Diverting
Pushes lightweight plastic caps or vials off a conveyor belt, where the stainless-steel construction resists humidity from nearby washdown processes.
Pick-and-Place Ejection
Ejects small moulded rubber parts from a tooling cavity, relying on the internal -S magnet and a DMSG sensor to confirm the ejection stroke completed.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X80SU the Right Cylinder?
When sizing this 12 mm bore, compare it against its neighbours: step down to an Ø8 for lighter 25 N tasks, or step up to a Ø16 if you need closer to 100 N. The U-style back cover provides a 90-degree port orientation, which helps route tubing cleanly in tight machinery. This 80 mm stroke falls well within the 250 mm maximum standard stroke, keeping the package compact.
Remember that a plain double-acting cylinder drifts if air pressure drops or the valve is centred—the TPU bumpers only soften the stroke end and will not act as a brake. If your assembly must hold a vertical load during an outage, 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 MI12X80SU 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 is M5x0.8.
No, it uses fixed TPU bumper pads to decelerate the piston at the stroke end. It is not an adjustable air cushion variant. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches.
