About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X280SU
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles precise actuation in compact spaces. The 280 mm stroke is a made-to-order length, exceeding the 250 mm standard maximum for this 12 mm bore. Its riveted round body relies on fixed TPU bumper pads to decelerate the piston at stroke end, while the integrated piston magnet (-S) supports CMSG, DMSG, and EMSG position switches.
The stainless-steel barrel and rod resist mild corrosion, offering a real advantage over painted alternatives in damp production areas. Thanks to its ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets and clevises. For practical sizing, plan for a safe working load of about 34 N, which means it can vertically lift roughly 2.9 kg with a 2:1 safety margin. Air connects via an M5x0.8 port, and the U back cover provides a 90-degree orientation for flexible plumbing.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X280SU Is Used
Lab Sample Dispenser
Pushes vial racks with a safe 34 N working load, utilizing the 280 mm travel to reach deep into testing chambers.
Small Parts Diverter
Cycles at 30-800 mm/s to deflect lightweight plastic components on a packaging line using the 90-degree U cover.
Textile Yarn Guide
Shifts thread guides horizontally where the stainless rod withstands humid dyeing environments without corroding.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X280SU the Right Cylinder?
When sizing this 12 mm bore, stepping down to an 8 mm bore drops the 0.5 MPa push force to 25.1 N, whereas moving up to a 16 mm bore increases it to 100.5 N. Because this 280 mm length is a non-standard, made-to-order stroke that significantly exceeds the 250 mm maximum, be mindful of rod bending under side loads and ensure proper guiding. The U-type back cover allows 90-degree mounting, but remember that a plain cylinder drifts when air is lost or a valve is centered; the bumpers only soften the stroke end rather than locking the load. For holding a suspended weight, 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 MI12X280SU 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 drifts if air is lost or the valve is centered; use an external rod lock or pilot check valve to hold a load. It uses fixed TPU bumper pads to decelerate at stroke end, not an adjustable air cushion.
