Airtac MI8~12 Stainless Steel Mini Cylinder MI8X15CA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X15CA is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 15mm 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 MI8X15CA
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles very compact 15 mm strokes with ease. Its riveted stainless barrel and Ø4 mm rod naturally resist mild corrosion, outperforming painted alternatives in damp or washdown settings. The integrated CA rear pivot clevis simplifies angled mounting, while the M5x0.8 port keeps pneumatic connections tight.
Because the bore is Ø8, it conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets. Plan for a safe working load of roughly 15 N, which equates to lifting about 1.3 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb end-of-stroke impact, and since 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 MI8X15CA Is Used
Micro Ejector Pins
Cycles short 15 mm ejector pins in small plastic injection moulds, safely applying its 15 N safe working load to release tiny parts without marring.
Lab Dispenser Dosing
Drives a micro-pneumatic dispenser for precise 1.3 kg vertical fluid dosing, relying on the stainless body to withstand chemical splashes and daily washdowns.
PCB Component Sorting
Pushes lightweight electronic components down a sorting chute using the CA clevis to accommodate the conveyor's slight pivot angle during transit.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X15CA the Right Cylinder?
When sizing this 8 mm bore, stepping up to the Ø10 bore is advisable if you need more force, as it yields 39.3 N at 0.5 MPa. There is no smaller standard MI bore, making this the most compact option available for ultra-light duties. If your application requires the piston to stay put after a valve centres or air pressure drops, note that this cylinder will drift; the fixed bumpers only decelerate the stroke end rather than locking the rod, so an external pilot check valve is required for load holding.
The 15 mm stroke is well within the 150 mm maximum, keeping the rod highly rigid and minimizing side-load bending risks. The CA pivot cover is perfect for articulating mechanisms, but remember that without the -S suffix, adding magnetic sensing is impossible.
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 MI8X15CA FAQ
This 8 mm bore cylinder features an M5x0.8 port and generates 25.1 N push / 18.8 N pull at 0.5 MPa, and 35.2 N push / 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
Yes, the Ø8 bore uses the ISO 6432 mounting interface for easy bracket compatibility. However, because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG switches; you would need the -S variant for sensing.
