Airtac MI8~12 Stainless Steel Mini Cylinder MI12X55SCA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X55SCA is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 55mm 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 MI12X55SCA
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles light actuation with a 55 mm stroke. The Ø12 mm bore uses an M5×0.8 air port and an M6×1.0 male rod thread. Its riveted stainless barrel and rod shrug off mild corrosion, outperforming painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb stroke-end impact without adding bulk.
Because it includes a piston magnet (-S), the unit supports CMSG, DMSG, and EMSG switches for position sensing. The CA rear cover provides a pivot clevis for articulated mounting. For practical sizing, plan for about 34 N of real work at 0.5 MPa, which lets it lift roughly 2.9 kg vertically against gravity.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X55SCA Is Used
Textile Yarn Guides
Shifts delicate thread guides across a 55 mm path; the stainless build resists humid dye-house environments while the CA clevis accommodates angular rod alignment.
Small Pouch Sealing Jigs
Closes light sealing bars with a 34 N safe working load. The integrated magnet allows a DMSG sensor to confirm the seal cycle before reopening.
Lab Sample Diverters
Pivots small fluidic routing gates via the CA pivot mount. The compact Ø12 round body fits easily into tight benchtop analyzer frames.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X55SCA the Right Cylinder?
When sizing this 55 mm stroke actuator, compare it against its neighbours: the Ø10 bore yields 39.3 N push, while the Ø16 bore offers 100.5 N at 0.5 MPa. If your payload drops, the smaller bore saves space; if friction spikes, step up to the 16 mm version. The CA clevis back cover suits pivoting loads, but remember that a plain cylinder drifts if air pressure is lost. To lock a suspended load mid-stroke, fit an external rod lock or pilot check valve, as the TPU bumpers only decelerate the end of travel and act as no brake.
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 MI12X55SCA FAQ
This double-acting cylinder has an M5×0.8 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.
Yes, the Ø12 bore adheres to ISO 6432 mounting dimensions, so it drops into standard mini-cylinder brackets and clevises. The -S suffix denotes a built-in magnet for CMSG, DMSG, or EMSG switches; a non-S SKU cannot take a sensor.
