About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X140U
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation tasks with ease. The 12 mm bore features an M5x0.8 port and an M6x1.0 male rod thread. Its 140 mm stroke falls well within the 250 mm standard limit, while the U back cover provides a 90-degree port and mounting orientation for tight spaces.
The rolled stainless barrel and rod shrug off mild corrosion, outlasting painted alternatives in damp environments. Because this SKU lacks the -S magnet, it cannot accept CMSG or DMSG switches. Fixed TPU bumper pads absorb end-of-stroke impact, and you can plan for a safe working load of roughly 34 N or lifting about 2.9 kg vertically with a 2:1 margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X140U Is Used
Small Part Ejection
Pushes lightweight plastic mouldings out of a machining fixture using 56.5 N of force at 0.5 MPa.
Package Deflection
Extends 140 mm to divert small cartons on a packaging line, fitting neatly via the 90-degree U cover.
Lab Sample Sorting
Moves test tubes between stations where the stainless body resists humidity and chemical wipe-downs.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X140U the Right Cylinder?
When sizing this 12 mm bore, stepping down to the Ø8 version drops the 0.5 MPa push force to 25.1 N, whereas moving up to the Ø16 bore raises it to 100.5 N. The U-style rear cover simplifies 90-degree mounting, but remember that venting the air causes the piston to drift, so add an external pilot check valve if you need to suspend a load safely. At 140 mm of travel, keep side-loading minimal to avoid bending the 6 mm rod.
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 MI12X140U FAQ
It generates a push force of 56.5 N and a pull force of 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, and the air port is M5x0.8.
No, this specific SKU does not include a magnet, so CMSG, DMSG, or EMSG switches cannot be used. You would need the -S variant for sensing. It relies on fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
