About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X180SU
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation tasks with ease. The Ø12 mm bore features an M5x0.8 port and a 180 mm stroke, while the integrated piston magnet allows direct fitting of CMSG, DMSG or EMSG switches for position sensing.
Its riveted round-body construction pairs a stainless barrel and rod to shrug off mild corrosion in damp or washdown environments. The fixed TPU bumper pads absorb end-of-stroke impact, and the U-type 90-degree rear cover simplifies perpendicular mounting. For practical sizing, plan for roughly 34 N of usable work at 0.5 MPa, which translates to lifting about 2.9 kg vertically with a 2:1 safety margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X180SU Is Used
PCB Depaneling Router
Pushes a small cutting fixture along an 180 mm track, using the 56.5 N force to separate circuit boards cleanly.
Lab Dispense Valve
Actuates a precision needle valve for reagent dosing, where the stainless body resists chemical humidity.
Bin Diverter Flap
Pivots a light sorting gate via the 90-degree U cover, handling small plastic parts at speed.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X180SU the Right Cylinder?
If your task needs less force, the Ø10 bore provides 39.3 N push at 0.5 MPa, whereas stepping up to the Ø16 bore yields 100.5 N for heavier guides. This 180 mm stroke is well within the 250 mm maximum for the Ø12 bore, though at this length you should ensure rigid guidance to prevent rod bending under side loads. The standard ISO 6432 mounting dimensions let you drop this cylinder into standard mini-cylinder brackets and clevises.
Because the U-type cover provides a 90-degree mounting axis, verify your pivot geometry clears the 180 mm stroke length. The internal magnet supports reed and electronic sensors, but remember that venting the air supply or centering the valve will cause the piston to drift; the TPU pads only decelerate the stroke end rather than locking the load. Use a pilot-operated check valve if you need to hold a vertical position.
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 MI12X180SU FAQ
This Ø12 mm bore cylinder has an M5x0.8 port. It generates 56.5 N push and 42.4 N pull at 0.5 MPa, 79.1 N push and 59.4 N pull at 0.7 MPa, with a theoretical maximum of 11.5 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. You must add an external rod lock or pilot check valve to hold a suspended load.
