About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30SUFA
Delivering 25.1 N of push force at 0.5 MPa, the AirTAC MI8X30SUFA is a compact double-acting round-body mini cylinder built for tight spaces. Its stainless-steel barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. The riveted construction keeps the unit light, while fixed TPU bumper pads absorb the impact at stroke end to protect your mechanism. An M5x0.8 port supplies the air, and the built-in piston magnet allows direct mounting of CMSG, DMSG or EMSG sensors for position feedback.
Because the theoretical output is limited, plan for a safe working load of about 15 N (roughly 60 percent of the 0.5 MPa rating) rather than the absolute maximum. For vertical moves, this translates to lifting around 1.3 kg safely with a 2:1 margin. The rear U cover provides a 90-degree port orientation for neat tubing, and the body conforms to ISO 6432 mounting dimensions, dropping easily into standard mini-cylinder brackets and clevises.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30SUFA Is Used
Micro-clip ejection
Pushes small plastic clips out of an injection mould with a safe 15 N working load, preventing damage to delicate tooling.
Lab sample diverter
Switches a tiny fluidic diverter gate in a diagnostic analyser, where the stainless body resists humid lab conditions.
PCB pin insertion
Taps thin connector pins into printed circuit boards using position feedback from the built-in magnet and an EMSG sensor.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X30SUFA the Right Cylinder?
Choosing this 8 mm bore makes sense when your task requires only 15 N of real work at 0.5 MPa; if you need more push, stepping up to the 10 mm bore raises the output to 39.3 N. Since 8 mm is the smallest available MI size, there is no smaller option for lighter duties. The included FA flange simplifies front mounting, while the U back cover handles rear pivot needs. Remember that a plain cylinder drifts if air pressure drops or the valve is centred—the TPU pads only soften the end of travel, so add an external rod lock or pilot check valve if you must hold a load vertically. With a 30 mm stroke, side-load and rod-bending stress are minimal, but keep the guide alignment true to protect the 4 mm rod.
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 MI8X30SUFA FAQ
This double-acting cylinder has an M5x0.8 port and generates a push force of 25.1 N and a pull force of 18.8 N at 0.5 MPa. At 0.7 MPa, push is 35.2 N and pull is 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
No, the base MI uses fixed TPU bumper pads that merely decelerate the stroke end, not an adjustable air cushion. Additionally, it cannot hold a load if air is lost; you would need an external rod lock or pilot check valve. The -S magnet supports CMSG, DMSG and EMSG sensors.
