Airtac MI8~12 Stainless Steel Mini Cylinder MI12X260SU
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X260SU is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 260mm 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 MI12X260SU
Generating 56.5 N of push force at 0.5 MPa, the AirTAC MI12X260SU is a double-acting round-body mini cylinder built for compact automation. This specific 260 mm stroke unit is a non-standard, made-to-order configuration that exceeds the usual 250 mm maximum standard stroke for this 12 mm bore. The stainless-steel barrel and piston rod supply solid mild-corrosion and washdown resistance, outperforming painted alternatives in damp settings. Because the bore falls within the Ø8-Ø25 range, it shares the ISO 6432 mounting interface, sliding directly into standard mini-cylinder brackets and clevises. The U-style rear cover provides a 90-degree port orientation for tight spatial routing. A built-in piston magnet (-S) enables position detection with CMSG, DMSG or EMSG switches, while fixed TPU bumper pads absorb the end-of-stroke impact. For practical sizing, plan for a safe working load of roughly 34 N, which translates to lifting about 2.9 kg vertically with a 2:1 safety margin. Air connects via an M5x0.8 port.
Operating between 0.15 and 1.0 MPa at speeds of 30-800 mm/s, this riveted stainless actuator is driven by filtered 40 µm air. The Ø6 mm piston rod features an M6x1.0 male thread for direct part attachment. Remember that the fixed bumpers only decelerate the stroke end; they do not function as an adjustable air cushion.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X260SU Is Used
PCB Depanelling Ejector
Uses the 56.5 N push force at 0.5 MPa to safely eject freshly routed circuit boards from a fixture without marring the delicate surface.
Small Parts Sorter Diverter
Leverages the 260 mm non-standard stroke to push lightweight plastic components from a narrow conveyor belt into a secondary packing chute.
Lab Reagent Rack Pusher
The stainless-steel construction resists mild chemical washdown, while the 90-degree U cover port keeps pneumatic tubing neatly routed inside the enclosure.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X260SU the Right Cylinder?
When sizing this 12 mm bore actuator, check the neighbouring capacities to ensure optimal performance. Stepping down to the Ø8 bore drops the push force significantly to 25.1 N at 0.5 MPa, whereas moving up to the Ø16 bore increases it to 100.5 N. If your application requires holding a vertical load during air loss or valve centering, note that a standard cylinder drifts under load—the TPU bumper only softens the stroke end and acts as neither a lock nor a brake. You must integrate an external rod lock or a pilot-operated check valve to secure the position. Additionally, the extended 260 mm stroke on this compact body increases the risk of side-loading and rod bending, so careful guide alignment is critical to prevent premature seal wear. The -S magnet pairs directly with CMSG, DMSG and EMSG sensors, and the U back cover simplifies 90-degree mounting.
Quick checklist

- ✓ 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 MI12X260SU FAQ
This 12 mm bore cylinder uses an M5x0.8 port and generates 56.5 N push / 42.4 N pull at 0.5 MPa, and 79.1 N push / 59.4 N pull at 0.7 MPa. The theoretical maximum force is 11.5 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
No, the base MI uses fixed TPU bumper pads that merely decelerate the stroke end; it lacks the adjustable air cushion found on MIC variants. Furthermore, the piston drifts if air is lost or the valve is centered, so you must add an external rod lock or pilot check valve to hold a load securely.
