Airtac MI8~12 Stainless Steel Mini Cylinder MI8X100U
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X100U is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 100mm 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 MI8X100U
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder suits compact 8 mm bore tasks. The riveted round-body construction shrinks the footprint while the stainless barrel and rod shrug off mild corrosion in damp environments. Fixed TPU bumper pads absorb end-of-stroke impacts, and the U back cover provides a 90-degree port and mounting orientation for tight spaces.
Because the 8 mm bore carries an M5x0.8 port and an M4x0.7 male rod thread, it drops directly into standard ISO 6432 mini-cylinder brackets. Plan for a real work load of roughly 15 N (about 60 percent of the 0.5 MPa rating), which translates to lifting a 1.3 kg part vertically with a safe 2:1 margin. Note this SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X100U Is Used
Micro-clip insertion
Pushes delicate wire clips into PCB assemblies using the 25.1 N output, where the stainless body handles light flux splashes.
Small-part gate diverting
Actuates a lightweight flap to sort small plastic caps on a conveyor, using the 90-degree U cover to fit under the belt frame.
Lab tube ejection
Ejects filled 1.3 kg centrifuge tube racks from a testing carousel, relying on the fixed TPU pads to prevent glass breakage.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X100U the Right Cylinder?
If the 25.1 N push at 0.5 MPa feels marginal, stepping up to the Ø10 bore raises that to 39.3 N, while there is no smaller AirTAC MI option below 8 mm. The 100 mm stroke sits well within the 150 mm standard limit for this bore, though at full extension the slender 4 mm rod needs careful alignment to avoid side-load bending.
The U-type back cover simplifies 90-degree mounting, but remember a plain cylinder drifts if air pressure drops or the valve centres—the TPU pads only soften the stroke end, they do not lock the load. Add an external rod lock or pilot check valve for holding. Since this specific SKU has no -S suffix, position sensing is unavailable.
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 MI8X100U FAQ
At 0.5 MPa it pushes 25.1 N and pulls 18.8 N. At 0.7 MPa it pushes 35.2 N and pulls 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa. The air port is M5x0.8 and the male rod thread is M4x0.7.
Yes, the 8 mm bore uses the ISO 6432 mounting interface, so it fits standard mini-cylinder clevises and brackets. However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG magnetic switches.
