About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SUTC
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles light-duty positioning with ease. The Ø12 mm bore uses an M5x0.8 air port and an M6x1.0 male rod thread. Its stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. The riveted construction keeps the body compact, while fixed TPU bumper pads absorb impact at the stroke ends.
Because it carries an internal magnet (-S), you can mount CMSG, DMSG or EMSG switches for position sensing. Plan for a safe working load of about 34 N, which translates to lifting roughly 2.9 kg vertically with a 2:1 safety margin. The U rear cover provides a 90-degree port orientation, and the included TC trunnion accessory simplifies pivot mounting.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SUTC Is Used
Electronic Component Sorting
Pushes small electronic parts down a testing chute using a 34 N safe working load, relying on the TC trunnion to pivot smoothly during the 50 mm travel.
Carton Flap Folding
Folds light cardboard flaps on a packaging line where the 2.9 kg vertical lift capacity easily handles the material weight in damp washdown environments.
Lab Sample Diverting
Actuates a diverter gate for laboratory vials, using the built-in magnet with a DMSG sensor to confirm stroke completion in compact machinery.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X50SUTC the Right Cylinder?
When sizing this 12 mm bore, compare it against the smaller Ø10 bore (39.3 N push at 0.5 MPa) and the larger Ø16 bore (100.5 N push at 0.5 MPa) to ensure you have the right thrust. The 50 mm stroke is well within the 250 mm maximum standard stroke for this size, avoiding special order requirements. With a 6 mm rod, keep side loads minimized to prevent bending.
This SKU includes the TC trunnion mount and a 90-degree U back cover. Remember that a standard cylinder drifts if air pressure drops or the valve is centered; the TPU bumpers only decelerate the stroke end and do not act as a brake. Use a pilot-operated check valve or external rod lock if you need to hold a load securely in place.
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 MI12X50SUTC FAQ
This 12 mm bore cylinder features an M5x0.8 port. It generates 56.5 N push and 42.4 N pull at 0.5 MPa, 79.1 N push and 59.4 N pull at 0.7 MPa, with a theoretical maximum force of 11.5 kgf at 1.0 MPa.
Yes, the Ø12 bore uses the ISO 6432 mounting interface, so it drops into standard mini-cylinder brackets and clevises. The -S suffix denotes a built-in magnet for CMSG, DMSG or EMSG switches, and the U cover provides a 90-degree port orientation.
