About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X65U
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation tasks with ease. The Ø12 mm bore features an M5x0.8 port and a 65 mm stroke, relying on fixed TPU bumper pads to decelerate the piston at both ends without adjustable cushioning. Its stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments.
Because it follows the ISO 6432 mounting interface, the unit 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 lifts roughly 2.9 kg vertically with a 2:1 safety margin. The U back cover provides a 90-degree port orientation for tight spatial constraints. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG position switches without upgrading to the -S variant.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X65U Is Used
PCB Depaneling Gate
Cycles a lightweight routing blade to separate printed circuit boards, using the 56.5 N push force to cleanly sever frangible substrates without stressing components.
Carton Flap Folder
Employs the 90-degree U cover to tuck minor flaps on small pharmaceutical cartons prior to sealing, fitting neatly into compact packaging line frames.
Lab Dispenser Trigger
Actuates a precision metering valve for reagent dosing, where the stainless construction withstands incidental chemical splashes during daily operation.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X65U the Right Cylinder?
When sizing this 12 mm bore actuator, compare it against its neighbours: the smaller Ø8 generates 25.1 N of push at 0.5 MPa, while the larger Ø16 provides 100.5 N, giving you a clear upgrade path if your load demands shift. The 65 mm stroke is well within the 250 mm maximum standard stroke for this bore, keeping the rod bending risk low even without a guide. This model includes the U back cover for 90-degree mounting flexibility, alongside standard LB foot, FA flange, SDB pivot and TC trunnion options.
Remember that a plain double-acting cylinder drifts if air pressure drops or the valve is centred, as the fixed TPU bumpers only soften the end-of-stroke impact rather than locking the rod. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your circuit. Furthermore, because this SKU is non-magnetic, you must select the -S version if your application requires electronic position sensing.
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 MI12X65U FAQ
This 12 mm bore cylinder features an M5x0.8 port and generates a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. At 0.7 MPa, the push increases to 79.1 N and the pull to 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
Yes, the Ø12 bore adheres to ISO 6432 mounting dimensions, allowing it to fit standard mini-cylinder clevises and brackets. However, because this specific SKU lacks a magnet, it cannot host CMSG, DMSG or EMSG switches; you must specify the -S variant for position sensing.
