Airtac MI8~12 Stainless Steel Mini Cylinder MI12X230U
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X230U is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 230mm stroke, M5×0.8 air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X230U
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles precise linear motion across its 230 mm stroke. The Ø12 mm bore uses an M5x0.8 air port and a Ø6 mm piston rod with an M6x1.0 male thread. Its riveted round-body construction shrinks the footprint while the stainless barrel and rod resist mild corrosion in damp or washdown settings better than painted alternatives.
Because the 56.5 N rating leaves a margin for friction, plan for about 34 N of actual work at 0.5 MPa. That translates to lifting roughly 2.9 kg vertically with a safe 2:1 factor. The U-style back cover provides a 90-degree port orientation for tight routing, and the fixed TPU bumper pads absorb end-of-stroke impact. Since this SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG switches.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X230U Is Used
Textile Loom Yarn Guide
Shifts a yarn guide across a 230 mm path; the stainless rod tolerates fibrous dust and humid textile mill environments without seizing.
Small Parts Sorter Diverter
Pushes lightweight plastic components off a belt using 56.5 N of thrust, relying on the U cover for compact 90-degree hose routing.
Lab Sample Drawer Actuator
Extends a sample tray 230 mm in a diagnostic machine where the 2.9 kg safe lift capacity easily handles the tray and reagent rack weight.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X230U the Right Cylinder?
When sizing this 230 mm stroke unit, verify your side-load limits, as a Ø6 mm rod extending this far is vulnerable to bending if the load is not guided. If you need less push, the Ø10 bore offers 39.3 N at 0.5 MPa; if your payload is heavier, step up to the Ø16 bore which provides 100.5 N. The ISO 6432 mounting dimensions on this Ø12 body let you drop it straight into standard mini-cylinder brackets, foot mounts (LB) or flanges (FA).
Remember that the fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as a brake. If air pressure drops or the valve is centred, the rod will drift and drop the load. To hold a vertical payload securely, fit an external rod lock or a pilot-operated check valve rather than relying on the cylinder itself.
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 MI12X230U FAQ
This Ø12 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.
No, this specific SKU does not include the -S magnet, so it cannot host CMSG, DMSG or EMSG switches. You would need the -S variant for position sensing, though the ISO 6432 mounting dimensions allow easy bracket integration.
