Airtac MI8~12 Stainless Steel Mini Cylinder MI12X45SU
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X45SU is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 45mm 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 MI12X45SU
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact 45 mm stroke tasks with efficiency. The riveted stainless barrel and Ø6 mm rod naturally shrug off mild corrosion, giving it a clear lifespan advantage over painted alternatives in damp production zones. Because it follows ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder clevises without redesigning your fixture.
The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for precise end-of-stroke detection, while the rear U cover provides a 90-degree port orientation for tight routing. Plan for roughly 34 N of actual work at 0.5 MPa to maintain smooth operation, which translates to safely lifting about 2.9 kg vertically against gravity. Fixed TPU bumper pads absorb the impact at stroke extremes, and the M5x0.8 air port supplies the pneumatic flow for this bore size.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X45SU Is Used
Small Part Ejection
Pushes lightweight molded plastic parts out of an injection mold cavity using 56.5 N of force at 0.5 MPa.
Package Diverting
Actuates a short 45 mm diverter arm to sort small cardboard cartons on a packaging conveyor line.
Lab Sample Handling
Moves delicate diagnostic cassettes within an analytical instrument where the stainless body resists chemical mist.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X45SU the Right Cylinder?
When sizing this 12 mm bore, the smaller Ø8 generates 25.1 N of push at 0.5 MPa, whereas stepping up to the Ø16 yields 100.5 N, giving you a clear upgrade path if your payload increases. The U back cover simplifies plumbing in confined spaces, but remember that a standard cylinder drifts if air pressure drops or the valve is centered; to suspend a load securely, integrate an external rod lock or pilot check valve rather than relying on the bumpers. For this 45 mm stroke, side-load stress on the Ø6 mm rod is minimal, though keeping the load axially aligned will maximize seal life.
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 MI12X45SU FAQ
At 0.5 MPa it provides 56.5 N push and 42.4 N pull. At 0.7 MPa it delivers 79.1 N push and 59.4 N pull. The theoretical maximum force is 11.5 kgf at 1.0 MPa, and the air port is M5x0.8.
No, it uses fixed TPU bumper pads to decelerate at the stroke end rather than an adjustable air cushion. Additionally, it will drift if air is lost; you must use an external rod lock or pilot check valve to hold a suspended load.
