Airtac MI8~12 Stainless Steel Mini Cylinder MI12X70CA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X70CA is a genuine double acting round-body mini air cylinder with a Ø12mm 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 MI12X70CA
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles light actuation with a 70 mm stroke. The Ø12 mm bore uses an M5x0.8 air port and a Ø6 mm piston rod with an M6x1.0 male thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted-steel minis in damp or washdown environments. Built with a riveted round body, it conforms to ISO 6432 mounting dimensions so it drops directly into standard mini-cylinder brackets.
Fixed TPU bumper pads absorb impact at the stroke ends, though they decelerate rather than act as an adjustable air cushion. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches. In practice, you can plan for roughly 34 N of real work at 0.5 MPa, or lift about 2.9 kg vertically with a 2:1 safety margin, letting you match the cylinder to actual part weights.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X70CA Is Used
Small Part Ejection
Pushes lightweight plastic mouldings out of an injection press using the 56.5 N push force at 0.5 MPa, with the CA clevis accommodating slight angular misalignment.
Package Deflection
Actuates a deflector gate on a sorting line, relying on the stainless build to resist humidity and the 70 mm stroke to nudge small cartons.
Lab Sample Routing
Indexes test tubes into a scanning station where the compact riveted body saves space and the fixed TPU bumpers prevent glass breakage at stroke end.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X70CA the Right Cylinder?
When sizing this 12 mm bore, the smaller Ø8 generates 25.1 N of push at 0.5 MPa, while the larger Ø16 provides 100.5 N, giving you clear steps if the load changes. This CA version includes a rear pivot clevis, making it perfect for angular load alignment alongside LB foot, FA flange or TC trunnion options. The 70 mm stroke is well within the 250 mm maximum, but side loads should still be minimized to prevent rod bending.
Remember that a plain double-acting cylinder drifts when air is removed or the valve is centered, as the TPU bumpers only soften the end-of-stroke impact and do not function as a brake. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated 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 MI12X70CA FAQ
The Ø12 mm bore features an M5x0.8 port. It generates 56.5 N push and 42.4 N pull at 0.5 MPa, increasing to 79.1 N push and 59.4 N pull at 0.7 MPa. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant (MI12X70CA-S) for magnetic sensing. It uses the ISO 6432 mounting interface and fixed TPU bumper pads rather than an adjustable air cushion.
