About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X30SUTC
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact actuation with ease. The Ø12 mm bore uses an M5x0.8 air port and an M6x1.0 male rod thread. Its riveted round body and stainless construction resist mild corrosion, making it highly suitable for damp or washdown environments where painted alternatives fail. The built-in piston magnet allows seamless integration with CMSG, DMSG, or EMSG switches for position sensing.
For practical sizing, plan for a safe working load of about 34 N, which is roughly 60 percent of the 0.5 MPa rating. This equates to lifting a 2.9 kg part vertically with a two-to-one safety margin. The cylinder relies on fixed TPU bumper pads to decelerate the stroke end, and its ISO 6432 mounting dimensions ensure it drops directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X30SUTC Is Used
Small Parts Ejection
Provides the 56.5 N push force needed to eject small molded plastic components from a fixture on an assembly line.
Package Diverting
Uses the TC trunnion mount and 30 mm stroke to push lightweight cardboard cartons onto a secondary packaging belt.
Lab Sample Handling
The stainless steel build withstands wipe-down chemicals in laboratory automation while positioning test tubes precisely.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X30SUTC the Right Cylinder?
When sizing this actuator, compare it against its neighbors: the smaller Ø10 bore provides 39.3 N of push, while the larger Ø16 offers 100.5 N at 0.5 MPa. This model includes a U 90-degree rear cover and a TC trunnion mount, giving you flexible pivot options for varying machine geometries. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the TPU bumpers only soften the end of stroke and will not lock the load. To maintain vertical position during an air failure, add 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 MI12X30SUTC FAQ
At 0.5 MPa it provides 56.5 N push and 42.4 N pull. At 0.7 MPa it provides 79.1 N push and 59.4 N pull. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port is M5x0.8 and the male rod thread is M6x1.0.
No, the base MI series uses fixed TPU bumper pads to decelerate the piston at the stroke end rather than an adjustable air cushion. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors, and the U back cover provides a 90-degree port orientation.
