Airtac MI8~12 Stainless Steel Mini Cylinder MI12X35SU
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X35SU is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 35mm 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 MI12X35SU
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 riveted round-body construction pairs a corrosion-resistant barrel and rod with fixed TPU bumper pads that absorb stroke-end impacts. Because it features the built-in -S piston magnet, it is fully ready for CMSG, DMSG or EMSG position switches.
The Ø12 bore uses an M5x0.8 port and a 6 mm rod with an M6x1.0 male thread. It conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets. For real-world sizing, plan for a safe working load of about 34 N, which means it can vertically lift roughly 2.9 kg with a 2:1 safety margin. The U back cover provides a 90-degree port and mounting orientation for tight spaces.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X35SU Is Used
PCB Component Placement
Uses the 56.5 N push stroke to press small electronic connectors onto circuit boards without damaging delicate substrates.
Lab Sample Diverting
Leverages the stainless build and 2.9 kg vertical lift capacity to route fluid vials through cleanroom diagnostic machinery.
Carton Flap Folding
Employs the 35 mm stroke and 90-degree U cover to tuck small cardboard flaps on compact packaging lines.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X35SU the Right Cylinder?
When sizing this 35 mm stroke actuator, compare it against adjacent bores: the Ø10 generates 39.3 N push at 0.5 MPa, while the Ø16 steps up to 100.5 N. If your machine loses air or the valve centres, this plain cylinder will drift and cannot hold a load; the TPU pads only decelerate the end of travel. For suspended loads, add an external rod lock or pilot check valve. The -S magnet enables solid-state or reed sensors, and the 90-degree U rear cover simplifies plumbing in confined envelopes.
Quick checklist

- ✓ 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 MI12X35SU FAQ
At 0.5 MPa it provides 56.5 N push and 42.4 N pull. At 0.7 MPa it yields 79.1 N push and 59.4 N pull. The theoretical maximum force is 11.5 kgf at 1.0 MPa. This Ø12 bore uses an M5x0.8 air port.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. To maintain position, use an external rod lock or pilot check valve.
