About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X250CA
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles light-duty positioning across a 250 mm stroke. The Ø12 mm bore uses an M5x0.8 air port and a Ø6 mm piston rod with an M6x1.0 male thread. Because the barrel and rod are stainless, the riveted construction resists mild corrosion better than painted alternatives in damp or washdown environments. The integrated fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning.
For practical sizing, plan for roughly 34 N of actual work at 0.5 MPa, which translates to lifting about 2.9 kg vertically with a 2:1 safety margin. The rear CA pivot clevis accommodates angular rod movement during extension. As this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches; adding the -S variant is required for position sensing.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X250CA Is Used
Lab Sample Dispenser
Extends 250 mm to push vial racks into a testing chamber, where the stainless body withstands chemical splashes and the 56.5 N thrust securely indexes the tray.
Small Parts Diverter
Pivots via the CA clevis to knock lightweight plastic caps off a production line, using the 42.4 N pull force to retract the arm before the next batch arrives.
Carton Flap Folder
Cycles at speeds up to 800 mm/s to tuck minor corrugated flaps on a packaging conveyor, relying on the fixed TPU bumpers to soften the end-of-stroke impact.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X250CA the Right Cylinder?
When sizing this 12 mm bore actuator, compare it against its neighbours: the smaller Ø8 bore yields 25.1 N of push at 0.5 MPa, while the larger Ø16 bore provides 100.5 N, giving you a clear upgrade path if your load changes. The 250 mm stroke is the maximum standard length for this bore, so ensure your guiding structure prevents rod bending under any side-loading conditions. The CA rear clevis mount pairs well with pivot brackets but ensure the pin clearance allows free articulation. Remember that venting the air supply or centering the directional valve will cause the piston to drift, as the TPU bumpers only decelerate the end of stroke and do not function as a locking brake; utilize a pilot-operated check valve to hold a suspended load.
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 MI12X250CA FAQ
This 12 mm bore cylinder features an M5x0.8 air 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 force of 11.5 kgf at 1.0 MPa.
The Ø12 bore conforms to ISO 6432 mounting dimensions, allowing it to drop into standard mini-cylinder brackets and clevises. However, because this specific SKU lacks the -S magnet, it cannot support CMSG, DMSG, or EMSG magnetic position switches.
