About the AirTAC MI12
The AirTAC MI12 is a double-acting stainless-steel mini cylinder with a 12 mm bore and a 6 mm piston rod. At 0.5 MPa it pushes 57 N and pulls 42 N; at 0.7 MPa that rises to 79 N push and 59 N pull. Force depends on bore and pressure only, so every stroke on this page gives the same output.
All MI12 versions share M5×0.8 air ports, an M6×1.0 rod thread and rubber bumpers at both ends. The cylinder runs on filtered air between 0.15 and 1.0 MPa (proof 1.5 MPa), from -20 to +70 °C, at 30 to 800 mm/s. This page lists 159 stock order codes with strokes from 5 to 400 mm; the catalog maximum stroke is 250 mm, and the longer codes are non-standard strokes we already supply.

Theoretical output force (Ø12 mm)
| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | 59 N |
Push = pressure × bore area; pull subtracts the Ø6 mm rod area. Usable force is lower because of friction and back-pressure.

Where the MI12 Is Used
Small pushers and stoppers
About 57 N at 0.5 MPa suits light pushers, stoppers, gates and ejectors.
Packaging and assembly
Compact strokes for feeders, diverters and assembly stations.
Sensed positioning
Magnet versions report stroke ends to the PLC through cylinder sensors.
Choosing the Right MI12 Configuration
Start with the stroke. Pick the exact travel your machine needs; a longer stroke adds length, weight and air consumption without adding force. If your length is not listed, request a quote and we will confirm whether it can be built.
Then choose the back cover and mounting. The back cover sets how the rear of the cylinder is fixed or where its air enters (CA clevis-end cover, U radial-port cover). Mounting brackets on this page: FA front flange, LB foot bracket, SDB rear pivot bracket, TC center trunnion. R and U covers set the rear air inlet (axial or radial); a clevis-end cover with an SDB bracket or a TC trunnion lets the cylinder swing, while an FA flange or LB foot holds it rigid.
Finally pick the version: S adds a magnet for position sensors.
AirTAC MI12 FAQ
No. Every MI12 gives about 57 N push and 42 N pull at 0.5 MPa, whatever the stroke.
M5×0.8 ports.
Back covers: CA clevis-end cover, U radial-port cover. Brackets: FA front flange, LB foot bracket, SDB rear pivot bracket, TC center trunnion. Pick a pivoting cover or bracket when the load moves in an arc, a rigid one for straight-line loads.
Usually yes. Request a quote with the stroke, mounting and version and we will confirm whether it can be built, plus price and lead time.
0.15 to 1.0 MPa operating pressure (proof 1.5 MPa) and -20 to +70 °C on filtered air.
No. You can order a single MI12. Orders are processed and handed to the carrier within 3-5 business days.
