About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X125SU
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation with ease. Its riveted round body and Ø6 mm piston rod shrug off mild corrosion, making it superior to painted alternatives in damp or washdown environments. The 125 mm stroke operates at 30-800 mm/s, and fixed TPU bumper pads absorb impact at the stroke ends.
Because the bore is Ø12 mm, the air port is M5x0.8 and the male rod thread is M6x1.0. Plan for a real work rate of roughly 34 N, which is about 60 percent of the rated push. For vertical lifting, this translates to safely hoisting around 2.9 kg with a two-to-one safety margin. The built-in -S magnet allows seamless mounting of CMSG, DMSG or EMSG sensors for position detection.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X125SU Is Used
PCB Depaneling Router
Pushes a small cutting fixture along a 125 mm track, using the 56.5 N thrust to separate circuit boards without stressing surrounding components.
Bottle Divert Gate
Actuates a lightweight guide arm to sort plastic bottles on a packaging line, where the stainless body withstands routine washdowns.
Lab Sample Ejector
Extends 125 mm to push tested vials out of a centrifuge carousel, safely lifting roughly 2.9 kg of carrier mass vertically during retraction.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X125SU the Right Cylinder?
When sizing this bore, dropping down to the Ø10 model reduces thrust to 39.3 N, while stepping up to the Ø16 bore increases it to 100.5 N at 0.5 MPa. The rear U-style 90-degree cover provides flexible mounting orientation. Thanks to its ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises. Remember that the fixed TPU bumpers only decelerate the piston near the end of travel; they do not function as a lock. If your process requires the rod to stay put during air loss or valve centering, the piston will drift unless you fit 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 MI12X125SU FAQ
At 0.5 MPa it provides 56.5 N push and 42.4 N pull. At 0.7 MPa it provides 79.1 N push and 59.4 N pull. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port is M5x0.8 and the male rod thread is M6x1.0.
Yes to sensors, no to adjustable cushions. The -S suffix means it has a built-in piston magnet for CMSG, DMSG or EMSG switches. For deceleration, it relies on fixed TPU bumper pads. If you need adjustable air cushioning for high speeds, look at the MIC variant instead.
