About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X25U
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation with a 25 mm stroke. The Ø12 mm bore uses an M5x0.8 air port and an M6x1.0 male rod thread. Its riveted round body houses a stainless barrel and rod, offering mild corrosion resistance that outlasts painted aluminium in damp or washdown environments. Fixed TPU bumper pads absorb impact at the stroke ends, decelerating the piston smoothly.
This specific U variant features a 90-degree rear cover, orienting the supply port perpendicular to the body for tight manifold clearances. Note that this SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without switching to the -S version.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X25U Is Used
PCB Ejector Pins
Uses the 56.5 N push force to pop bare boards out of test fixtures without marring the surface, fitting neatly into electronics assembly lines.
Pouch Flap Folding
Deploys the 25 mm stroke to tuck packaging flaps on compact vertical form-fill-seal machines where a 90-degree port entry saves space.
Lab Sample Diverting
Leverages the stainless steel construction to withstand daily wipe-downs in diagnostic equipment while pushing lightweight sample racks.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X25U the Right Cylinder?
When sizing this 12 mm bore, compare it against its neighbours: the Ø8 generates 25.1 N of push at 0.5 MPa, while the Ø16 provides 100.5 N, giving you a clear upgrade path if the 56.5 N output is insufficient for your fixture. The 25 mm stroke keeps the rod short and highly resistant to bending under side loads. Remember that venting the air supply or centering the directional valve will cause the piston to drift, as the TPU bumpers only soften the end-of-stroke impact rather than locking the rod. To suspend a load mid-air, integrate an external pilot check valve or a dedicated rod lock.
Mounting options include LB foot brackets, FA flanges, SDB pivot blocks, and TC trunnions. The rear U cover provides a 90-degree port orientation, which helps route tubing cleanly in confined spaces. Because this exact model has no internal magnet, position detection is impossible unless you specify the -S magnet option for switch readiness.
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 MI12X25U FAQ
This 12 mm bore cylinder features an M5x0.8 air port and an M6x1.0 male rod thread. It generates 56.5 N push and 42.4 N pull at 0.5 MPa, increasing to 79.1 N push and 59.4 N pull at 0.7 MPa. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
Yes, the Ø12 mm bore conforms to ISO 6432 mounting dimensions, allowing it to drop into standard mini-cylinder clevises and brackets. However, this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you must select the -S variant for position sensing.
