About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X225CA
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 225 mm stroke with a CA rear clevis. The Ø12 mm bore uses an M5x0.8 air port and an M6x1.0 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown environments. Riveted construction keeps the body compact, while fixed TPU bumper pads absorb impact at the stroke ends.
Because it follows ISO 6432 mounting dimensions, the cylinder drops directly into standard mini-cylinder brackets. Plan for a safe working load of about 34 N, which lets you lift a 2.9 kg part vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to the -S variant.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X225CA Is Used
Package Diverter Arm
Pushes lightweight cardboard cartons on a packaging line using the 56.5 N thrust and 225 mm reach, with the CA clevis absorbing pivot stress.
Lab Sample Ejection
Ejects plastic test tubes from a wet processing station, leveraging the stainless steel rod to withstand mild chemical splashes.
Small Part Sorting
Actuates a sorting flap for small electronic components, safely moving items well under the 2.9 kg vertical lift threshold.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X225CA the Right Cylinder?
When sizing this 12 mm bore, stepping down to the Ø8 model drops the 0.5 MPa push force to 25.1 N, while stepping up to the Ø16 bore raises it to 100.5 N. The 225 mm stroke sits near the 250 mm maximum for this bore, so ensure your guiding structure prevents rod bending under side loads. The CA pivot clevis accommodates angular misalignment during extension. Remember that venting the air supply causes the piston to drift, as the TPU bumpers only decelerate the end of travel rather than locking the load; install a pilot check valve if you need to hold position vertically.
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 MI12X225CA FAQ
This 12 mm bore cylinder features an M5x0.8 port and generates 56.5 N push / 42.4 N pull at 0.5 MPa, 79.1 N push / 59.4 N pull at 0.7 MPa, with a theoretical maximum of 11.5 kgf at 1.0 MPa.
No, this specific SKU lacks a magnet and cannot accept CMSG, DMSG or EMSG switches. You must select the -S magnet variant to enable sensing on the stainless-steel round body.
