Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SCATC
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SCATC is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 80mm 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 MI8X80SCATC
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact 80 mm stroke tasks. The Ø8 mm bore uses an M5x0.8 port and an M4x0.7 male rod thread. Because the 25.1 N rating leaves little margin for friction, plan for about 15 N of real work, which safely lifts a 1.3 kg part vertically with a 2:1 safety factor.
The stainless-steel barrel and rod shrug off mild corrosion, giving it an edge over painted alternatives in damp areas. Its riveted round body matches ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets. The -S suffix adds a piston magnet for CMSG, DMSG or EMSG sensors, while fixed TPU bumper pads absorb stroke-end impact.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SCATC Is Used
Electronic Component Ejection
Pushes lightweight PCBs or connectors out of test fixtures using 25.1 N of force, relying on the 80 mm stroke to clear the work area completely.
Small Package Deflection
Diverts small envelopes on a sorting line where the stainless body resists humid warehouse conditions and the TC trunnion accommodates the pivot arc.
Lab Sample Actuation
Moves sample trays in testing equipment, using the built-in -S magnet with a DMSG sensor to confirm the 80 mm extension position for the controller.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SCATC the Right Cylinder?
At the smallest available MI bore, there is no smaller AirTAC mini cylinder for lighter duties; stepping up to the Ø10 bore raises the 0.5 MPa push force to 39.3 N if this 25.1 N unit stalls. The included CA pivot clevis and TC trunnion accessories suit swinging or articulated mounts. Because the 80 mm stroke is relatively long for an Ø8 rod, keep the load guided to prevent side-loading and rod bending.
Air pressure drives both extension and retraction, but cutting supply lets the piston drift freely. The TPU bumpers only decelerate the end of travel, so install a pilot-operated check valve or external rod lock if the mechanism must hold a vertical load during an air loss or valve centre state.
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 MI8X80SCATC FAQ
This double-acting cylinder generates 25.1 N push and 18.8 N pull at 0.5 MPa, or 35.2 N push and 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa. It features an M5x0.8 air port and a 4 mm piston rod.
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. You must add an external rod lock or pilot check valve to hold a vertical load safely.
