This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X40, the same code under the new prefix. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.
Airtac ACP Compact Cylinder ACP12X40
The AirTAC ACP Compact Cylinder ACP12X40 is a double acting DIN-standard tight/compact air cylinder with a Ø12mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE12X40 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X40
A double acting DIN-standard compact cylinder, the ACP12X40 packs a 12 mm bore and 40 mm stroke into a short hard-anodized aluminium body with an S45C hard-chrome rod and fixed TPU bumpers at both ends. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N on extension at 0.7 MPa. Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits slim fixtures where a full-length body will not.
Note that this model is discontinued: the current-production direct is the ACE12X40, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. The magnet is not fitted on this code; order the -S variant if you need CMSE or DMSE switch sensing.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X40 (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | 59 N |
| Max (@1.0 MPa) | 12 kgf | |
The ACE12X40 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP12X40 Is Used
PCB fixture clamping
The 56.5 N push at 0.5 MPa is enough to hold small circuit boards in a test jig, and the short body slots under low fixture lids.
Small-part ejection on assembly stations
A 40 mm stroke knocks light components off a conveyor or out of a nest; order the -S magnet code to add CMSE or DMSE end-position switches.
Lab and dispensing head actuation
Compact 12 mm bore motion for probe or micro-dispense heads, running 30-500 mm/s on clean 40 um filtered air.
Replacing the Airtac ACP Compact Cylinder ACP12X40 with the ACE12X40
At 56.5 N push, the 12 mm bore suits light clamping and small-part ejection; step up to the 16 mm bore (100.5 N push at 0.5 MPa) for roughly double the force, or down to a direct-acting mini slide if you need side loads. The 40 mm stroke sits inside the 50 mm standard maximum for this bore, so it is a catalogue item. Remember the piston drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. Female M3x0.5 rod thread, M5x0.8 ports, PT supply thread, and the ACE12X40 is the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE12X40
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACP Compact Cylinder ACP12X40 FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa push is 79.2 N and pull 59.4 N; the theoretical maximum is 11.5 kgf at 1.0 MPa. It is double acting, so air drives the rod in both directions, and it runs at 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
The short ISO 21287-class aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot and CA/CB clevis options. The ACP12X40 itself is discontinued - the current direct is the ACE12X40 (same bore, stroke and force class); confirm the ISO 21287 mounting dimensions before ordering.
