Airtac MI8~12 Stainless Steel Mini Cylinder MI12X20U
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X20U is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 20mm 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 MI12X20U
Generating 56.5 N of push and 42.4 N of pull at 0.5 MPa, this double-acting stainless-steel mini cylinder suits compact automation. The Ø12 mm bore uses an M5x0.8 port and a Ø6 mm piston rod with an M6x1.0 male thread. Its 20 mm stroke and 90-degree U back cover fit neatly into tight corner assemblies.
The rolled stainless barrel and rod resist mild corrosion and washdown better than painted alternatives. Conforming to ISO 6432 mounting dimensions, it drops straight into standard mini-cylinder brackets. Plan for a safe working load of roughly 34 N, which means it can lift about 2.9 kg vertically with a 2:1 margin. Fixed TPU bumper pads absorb stroke-end impact, and because this SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X20U Is Used
Gripper Actuation
Drives small pneumatic grippers handling electronic components on PCB assembly lines.
Diverter Flap
Pivots a short 20 mm diverter arm to route small plastic parts on packaging conveyors.
Clamp Mechanism
Secures lightweight aluminium jigs in place during low-force benchtop drilling tasks.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X20U the Right Cylinder?
If 56.5 N at 0.5 MPa is insufficient, step up to the Ø16 bore (100.5 N push); for lighter duties, the Ø10 bore offers 39.3 N. This SKU lacks a magnet, so position sensing is impossible unless you switch to the -S variant. The U back cover provides a 90-degree mounting pivot. Remember that venting the air causes the piston to drift, as the TPU pads only decelerate the end of travel rather than locking the load; employ a pilot check valve for suspension.
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 MI12X20U FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.1 N and pulls 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port is M5x0.8.
No, this specific SKU does not include a magnet. You must select the -S variant to mount CMSG, DMSG or EMSG switches for position detection.
