Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90U
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90U is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 90mm 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 MI12X90U
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation tasks with ease. The Ø12 mm bore uses an M5x0.8 air port and a Ø6 mm piston rod with an M6x1.0 male thread. Because the stainless barrel and rod resist mild corrosion, the unit survives damp environments better than painted alternatives. Its fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning.
Plan for a safe working load of roughly 34 N, which is about 60 percent of the 0.5 MPa rating. This translates to lifting a 2.9 kg part vertically with a 2:1 safety margin. The 90 mm stroke operates at 30-800 mm/s. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to the -S variant.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90U Is Used
PCB Depaneling Gate
Pushes a lightweight routing gate at 56.5 N to separate printed circuit boards, utilising the 90 mm stroke to clear the cutting head during retraction.
Carton Flap Tucking
Tucks small cardboard flaps on a washdown packaging line, where the stainless construction prevents corrosion from cleaning sprays.
Sensor Bracket Indexing
Indexes a 2.9 kg sensor bracket into a test fixture, relying on the U cover to keep the M5x0.8 air line routing neatly tucked at a right angle.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90U the Right Cylinder?
When sizing this 56.5 N bore, dropping down to the Ø10 MI yields 39.3 N, while stepping up to the Ø16 MI provides 100.5 N at 0.5 MPa. The included U back cover provides a 90-degree port and mounting orientation, making it easy to fit into tight machinery layouts where a straight axial port will not clear adjacent components. You can pair the body with LB foot, FA flange or TC trunnion brackets using the ISO 6432 mounting dimensions.
Remember that the fixed 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 after a pressure loss or valve centreing, the piston will drift unless you add an external rod lock or a pilot-operated check valve. With the 90 mm stroke, ensure your guiding structure handles side loads to prevent rod bending.
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 MI12X90U 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. To use CMSG, DMSG or EMSG switches, you must select the -S magnet variant. The cylinder uses ISO 6432 mounting dimensions and fixed TPU bumper pads rather than adjustable cushions.
