Airtac MI8~12 Stainless Steel Mini Cylinder MI8X5U
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X5U is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 5mm 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 MI8X5U
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles microscopic positioning tasks. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp environments. Its 5 mm stroke and U-type back cover orient the rear port at 90 degrees for tight spatial routing.
At the 0.5 MPa operating point, you can plan for roughly 15 N of actual work, which translates to lifting about 1.3 kg vertically with a 2:1 safety margin. The M5x0.8 air port feeds the 4 mm piston rod, and fixed TPU bumper pads absorb the end-of-stroke impact. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X5U Is Used
Micro-clip ejection
Pushes delicate electronic clips a mere 5 mm off a fixture, using the 15 N safe working load to avoid deforming the component.
Lab valve actuation
Short-stroke toggling of a small fluidic valve where the stainless body resists humidity and the 90-degree U cover keeps airlines tidy.
Sensor deflection
Provides a 5 mm physical nudge to test micro-switch levers, relying on fixed TPU bumpers to silence the impact at stroke end.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X5U the Right Cylinder?
As the smallest bore in the range, there is no smaller MI option below Ø8; if your task needs less than 15 N of working force, consider a mechanical spring rather than a pneumatic cylinder. Stepping up to the Ø10 bore raises the 0.5 MPa push force to 39.3 N, which is the next logical jump if this 5 mm stroke overpowers a delicate part. The 90-degree U back cover helps navigate cramped plumbing, and you can utilise standard ISO 6432 mini-cylinder mounting dimensions for your brackets. Remember that a plain cylinder drifts if air pressure drops, so add an external pilot check valve if you must prevent the load from creeping.
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 MI8X5U 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. This Ø8 bore uses an M5x0.8 air port and a 4 mm rod with an M4x0.7 male thread.
No, this specific SKU lacks the internal magnet, so CMSG, DMSG and EMSG switches will not function. You must order the -S variant for position sensing. The cylinder uses standard ISO 6432 mounting dimensions and fixed TPU bumper pads rather than an adjustable air cushion.
