Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCATC
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCATC is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 50mm 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 MI12X50SCATC
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles light actuation with precision. The Ø12 mm bore uses an M5x0.8 air port and an M6x1.0 male rod thread. Its riveted round body shrinks footprint while the stainless barrel and rod resist mild corrosion in damp environments better than painted alternatives.
Equipped with a piston magnet, the unit supports CMSG, DMSG, and EMSG switches for position sensing. It conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets. Plan for about 34 N of real work at 0.5 MPa, which means it lifts roughly 2.9 kg vertically with a 2:1 safety margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCATC Is Used
PCB Panel Ejection
Pushes delicate printed circuit boards out of a test fixture using a safe 34 N working load to avoid scratching components.
Blister Pack Flap Fold
Folds thin cardboard flaps on a small pharmaceutical cartoning line where the compact 50 mm stroke fits tight clearances.
Lab Sample Diversion
Actuates a pivot gate to sort vials on a diagnostic conveyor, relying on the stainless body for wipe-down resistance.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SCATC the Right Cylinder?
Sizing against its neighbors, the Ø12 bore sits between the Ø8 (25.1 N push) and the Ø16 (100.5 N push) classes. If your fixture drifts when air is lost or the valve centers, remember the fixed TPU bumper pads only decelerate the stroke end—they do not lock the rod. Use an external pilot check valve to hold a suspended load.
This configuration includes a CA rear pivot cover and a TC trunnion mount for articulating loads. The built-in magnet enables electronic or reed sensing, and the 50 mm stroke keeps rod bending stress minimal even under slight side-loading.
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 MI12X50SCATC FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N. At 0.7 MPa it pushes 79.1 N and pulls 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port is M5x0.8.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. Install an external rod lock or pilot check valve to hold suspended loads.
