About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X120CA
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 a 120 mm stroke. The Ø12 mm bore features an M5x0.8 port and a Ø6 mm piston rod with an M6x1.0 male thread. Its stainless barrel and rod resist mild corrosion, offering a real advantage over painted alternatives in damp or washdown-prone environments.
Built to ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets and clevises. It features a CA rear pivot cover for articulated mounting. Plan for roughly 34 N of actual work at 0.5 MPa, which means it lifts about 2.9 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb stroke-end impact, and because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X120CA Is Used
Lab Sample Ejection
Uses its 56.5 N push force at 0.5 MPa to reliably eject filled test tube racks from a centrifuge carousel without damaging the glass.
Small Parts Diverter
Articulates via the CA clevis to push lightweight plastic components off a conveyor belt onto an inspection track in dry packaging lines.
Carton Flap Tucking
Extends 120 mm to fold cardboard flaps on small pharmaceutical cartons, relying on the stainless rod to resist humid packing room conditions.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X120CA the Right Cylinder?
When sizing this 120 mm stroke actuator, compare it against its neighbors: the smaller Ø8 bore yields 25.1 N of push at 0.5 MPa, while the larger Ø16 bore provides 100.5 N. If your application requires position feedback, select the -S magnet variant instead, as this base model cannot host a sensor. The CA pivot back cover suits angular load alignment, but ensure side loading is minimized over the 120 mm extension to prevent rod bending.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered. The fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as a brake. To sustain a suspended load, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MI12X120CA FAQ
This Ø12 mm bore cylinder features an M5x0.8 air port. It generates a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. At 0.7 MPa, the push increases to 79.1 N and the pull to 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
No, this SKU lacks the internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you need the -S variant for sensing. Additionally, the fixed TPU bumper pads only decelerate the stroke end and do not hold the load. If air is lost, the piston drifts, so use an external pilot check valve for position holding.
