Airtac MI8~12 Stainless Steel Mini Cylinder MI12X85CA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X85CA is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 85mm 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 MI12X85CA
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. 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 alternatives in damp or washdown environments. The riveted construction keeps the body light, while fixed TPU bumper pads absorb the impact at stroke extremes.
Because it conforms to ISO 6432 mounting dimensions, this unit drops directly into standard mini-cylinder brackets and clevises. Plan for a safe working load of about 34 N (roughly 60% of the 0.5 MPa rating) to account for friction and dynamics. For vertical lifts, the 56.5 N output translates to lifting about 2.9 kg with a 2:1 safety margin. This specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to the -S version.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X85CA Is Used
Textile Yarn Guides
Shifts thread guide arms on spinning frames using the 56.5 N push force, with the stainless build resisting humid textile mill environments.
Lab Sample Diverters
Pivots small chute gates via the CA clevis to route vials, safely moving loads under 2.9 kg vertically without risking sensor interference.
Small Bag Tuckers
Tucks flaps on compact pouch packaging lines, where the 85 mm stroke and fixed TPU bumpers quietly absorb the end-of-stroke impact.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X85CA the Right Cylinder?
When sizing this 85 mm stroke model, compare it against its neighbours: the Ø10 bore yields 39.3 N of push at 0.5 MPa, while the Ø16 bore steps up to 100.5 N. If your application needs position sensing, select the -S magnet variant instead, as this base unit cannot accept a switch. The CA rear pivot cover is ideal for articulating mechanisms, and you can pair it with LB foot, FA flange or TC trunnion mounts using the ISO 6432 interface.
Remember that the fixed TPU bumpers only decelerate the piston near the end of travel; they do not act as a lock. If air pressure drops or the valve centres, the rod will drift and drop the load. To secure a suspended weight, install an external rod lock or a pilot-operated check valve. At 85 mm, also verify the rod side-loading to prevent premature bending of the Ø6 mm shaft.
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 MI12X85CA FAQ
This double-acting cylinder has an M5x0.8 port and generates 56.5 N push / 42.4 N pull at 0.5 MPa, and 79.1 N push / 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 CMSG, DMSG or EMSG switches cannot be used. You must order the -S variant for sensing capabilities. It uses the ISO 6432 mounting interface and a CA pivot cover.
