About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X14U
Delivering 56.5 N of push force at 0.5 MPa, this 12 mm bore double-acting actuator handles compact automation tasks. The 14 mm stroke is housed in a stainless-steel riveted round barrel, offering mild corrosion resistance for damp or washdown environments. Its ISO 6432 mounting interface ensures direct compatibility with standard mini-cylinder brackets and clevises.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. Plan for a safe working load of roughly 34 N, which lets you lift about 2.9 kg vertically with a 2:1 safety margin. The M5x0.8 port and fixed TPU bumper pads round out the build, while the U back cover provides a 90-degree mounting orientation.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X14U Is Used
Ejector Pins
Cycles short 14 mm ejector pins in packaging machinery, using the 56.5 N thrust to push lightweight cardboard blanks out of a forming die.
Small Part Diverting
Mounts via the 90-degree U cover to act as a compact diverter arm on a conveyor belt, reliably redirecting small plastic housings at high speeds.
Lab Sample Ejection
Ejects processed vial racks from a testing carousel, where the stainless-steel rod withstands occasional chemical splashes and mild washdown.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X14U the Right Cylinder?
When sizing this 12 mm bore, stepping down to the Ø8 version drops the push force to 25.1 N, whereas moving up to the Ø16 bore increases it to 100.5 N at 0.5 MPa. The 14 mm stroke keeps the rod extremely short, minimizing side-load and rod-bending risks even under abrupt directional changes.
Remember that the fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as a brake. If your process requires the rod to stay put during a pressure drop or valve centering, the piston will drift, so you must integrate an external rod lock or a pilot-operated check valve.
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 MI12X14U FAQ
This 12 mm bore cylinder pushes 56.5 N and pulls 42.4 N at 0.5 MPa. At 0.7 MPa, push is 79.1 N and pull is 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa. It uses an M5x0.8 air port and operates at speeds of 30-800 mm/s.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensor tracking. It uses standard ISO 6432 mounting dimensions and features a 90-degree U back cover.
