Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80CA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80CA 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 MI8X80CA
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact actuation with a 4 mm rod and an 80 mm stroke. The riveted round-body construction pairs a corrosion-resistant barrel with a CA rear clevis, making it ideal for damp or washdown environments where painted steel would degrade. Its M5x0.8 port and M4x0.7 male rod thread keep the envelope small, while fixed TPU bumper pads absorb the impact at stroke extremes without acting as an adjustable cushion.
Because the Ø8 bore conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets. For practical sizing, plan for roughly 15 N of usable work at 0.5 MPa, which translates to lifting about 1.3 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG reed switches.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80CA Is Used
Gripper Actuation
Provides the extend and retract motion for small pneumatic grippers handling lightweight electronic components on assembly lines.
Lab Dispenser Valve
Pivots via the CA clevis to accurately open and close small fluid dispensing valves in automated chemical mixing equipment.
Part Ejector
Pushes tiny molded plastic parts out of a machining fixture, relying on the stainless build to resist coolant mist.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80CA the Right Cylinder?
When sizing this 8 mm bore, the next step up is the Ø12 class, which jumps to 56.5 N of push at 0.5 MPa—useful if the 25.1 N here cannot overcome your friction. Since this is the smallest bore in the MI family, there is no smaller option; if 25.1 N is too much, you must add an external regulator. The CA pivot back cover is specifically designed for clevis mounting, allowing the cylinder to articulate smoothly on an arc. Remember that a plain double-acting cylinder drifts if air pressure is lost or the valve is centered; the TPU bumpers only soften the end-of-stroke impact and will not lock the load. For vertical applications requiring position holding, install an external pilot check valve.
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 MI8X80CA FAQ
This 8 mm bore cylinder features an M5x0.8 port and an 80 mm stroke. It generates 25.1 N push and 18.8 N pull at 0.5 MPa, increasing to 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.
No, this specific SKU does not include the -S magnet, so CMSG, DMSG or EMSG switches cannot be used. You would need the -S variant for position sensing. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
