About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X225U
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles a 225 mm stroke with a 90-degree U rear cover for compact pivot mounting. The riveted round body and M5x0.8 port keep the frame small, while the stainless barrel shrugs off mild washdown better than painted alternatives. Because it lacks a magnet, this specific SKU cannot host CMSG, DMSG or EMSG sensors; you must specify an -S variant for position detection.
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. Fixed TPU bumper pads absorb the impact at stroke extremes to protect the mechanism, though they do not offer adjustable deceleration. Its Ø12 mm bore adheres to ISO 6432 mounting dimensions, ensuring it drops directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X225U Is Used
PCB Depaneling Gate
Pushes a lightweight routing gate across 225 mm to separate printed circuit boards, utilising the 56.5 N push force to overcome mild guide friction.
Small Parts Diverter
Extends a deflector flap on a conveyor belt to sort small plastic housings, relying on the 90-degree U cover for a flush side-mount pivot.
Lab Sample Ejector
Ejects filled micro-tube racks from a testing carousel, where the stainless steel construction resists humidity and chemical splashes.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X225U the Right Cylinder?
Sizing this 12 mm bore against its neighbours shows a clear step in capability: the smaller Ø8 tops out at 25.1 N push, while the larger Ø16 jumps to 100.5 N. If your fixture exceeds the safe 34 N working load, step up to the 16 mm bore. At 225 mm, this stroke sits near the top of the 250 mm standard limit for this size, so ensure your front mounting guides the load to prevent rod bending. The 90-degree U back cover suits tight corner installations.
Remember that venting the air supply causes the piston to drift, as the TPU bumpers only soften end-of-stroke impacts rather than locking the rod. To suspend a load safely during an air loss event, fit an external pilot-operated check valve or a dedicated rod lock. Furthermore, without the -S magnet option, this cylinder cannot support magnetic sensing.
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 MI12X225U 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, and 79.1 N push / 59.4 N pull at 0.7 MPa. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
The Ø12 bore uses ISO 6432 mounting dimensions, so it fits standard mini-cylinder clevises and brackets. However, because this specific SKU lacks a magnet, it cannot support CMSG, DMSG or EMSG sensors; you need an -S variant for position detection.
