Airtac MI8~12 Stainless Steel Mini Cylinder MI8X70CA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X70CA is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 70mm 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 MI8X70CA
Delivering 25.1 N of push force at 0.5 MPa, this compact 8 mm bore actuator handles delicate positioning tasks. The stainless-steel barrel and piston rod shrug off mild moisture, outperforming painted alternatives in damp settings. Its 70 mm stroke operates through a 1/8" port, while fixed TPU bumper pads absorb end-of-travel impacts.
Because the rod generates just 25.1 N, plan for roughly 15 N of actual work to maintain smooth motion. Vertically, it lifts about 1.3 kg safely with a 2:1 margin. The riveted round body drops into standard ISO 6432 mini-cylinder brackets, and the rear CA pivot clevis accommodates angular alignment. Note that this SKU lacks a magnet, so it cannot accept CMSG or DMSG position switches without upgrading to an -S variant.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X70CA Is Used
Electronic Component Sorting
Pushes lightweight PCBs or resistors along a conveyor with its 25.1 N thrust, utilizing the 70 mm travel to clear the processing lane.
Lab Sample Diverting
The stainless construction tolerates wipe-down chemicals, while the CA rear clevis allows the actuator to pivot as it routes small vials into testing carousels.
Micro-Clamp Actuation
Secures delicate plastic housings during ultrasonic welding, applying a gentle 15 N working force to prevent part deformation.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X70CA the Right Cylinder?
When sizing this 8 mm bore, stepping up to the 10 mm bore raises the 0.5 MPa push force to 39.3 N for heavier resistance; since 8 mm is the smallest available, dropping below 25.1 N requires a different family entirely. The 70 mm stroke is well within the 150 mm standard limit, keeping the assembly rigid. If your process loses air or the valve centers, the piston drifts freely—the TPU bumpers only soften the stroke end, so add an external pilot check valve to suspend a load.
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 MI8X70CA FAQ
At 0.5 MPa it provides 25.1 N push and 18.8 N pull; at 0.7 MPa it yields 35.2 N push and 26.4 N pull, with a theoretical maximum of 5.1 kgf at 1.0 MPa. The air port is M5x0.8.
No, this specific SKU does not include a magnet, so CMSG, DMSG, or EMSG switches will not function. You must select the -S magnet variant for position sensing.
