This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X5, 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 ACPD Double Rod Compact Cylinder ACPD12X5
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X5 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X5 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X5
A double acting compact cylinder with a rod leaving both covers, the ACPD12X5 delivers an equal 42.4 N in each direction at 0.5 MPa (59.4 N at 0.7 MPa), because both strokes work on the rod-side area of the 12 mm bore. The 5 mm stroke and short ISO 21287-class body save roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into micro jigs and test fixtures where a full-length body will not fit.
The through-rod resists rotation and light side load and gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end, and the hard-anodized aluminium body pairs with an S45C hard-chrome rod. Note: this model is discontinued - the current-production direct is the ACED12X5, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X5 (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACPD Double Rod Compact Cylinder ACPD12X5 Is Used
Micro test fixture actuation
The 5 mm stroke and 42.4 N per direction at 0.5 MPa are enough to press a small probe or toggle a test switch on a PCB inspection bench, with the through-rod keeping the tool tip square.
Tiny part ejection in watchmaking
A short 5 mm kick from the 12 mm bore nudges watch pins or bushings off a locating nest without disturbing the setup, and the compact body fits inside the fixture plate.
Symmetric flag carrier
With rods on both covers, the rear rod can mount a flag for position sensing on a small assembly station - order the -S version to enable CMSE / DMSE switches.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X5 with the ACED12X5
At 42.4 N per side at 0.5 MPa, the 12 mm bore suits light clamping and small-part positioning only; step up to the 16 mm bore (75.4 N both ways) or the 20 mm bore (117.8 N) if your load needs more push. The 5 mm stroke sits well inside the 50 mm maximum standard stroke for this bore. The rod end is female M3x0.5 and the port is M5x0.8. This unit has no magnet - order the -S code if you want CMSE / DMSE switch capability. Since the ACPD is discontinued, spec the ACED12X5 as the current replacement and verify the ISO 21287 mounting face before ordering.
Replacement checklist
- ✓ Current-production ACE → ACED12X5
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPD Double Rod Compact Cylinder ACPD12X5 FAQ
Because a rod exits both covers, force is equal in both directions: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, with a maximum of 8.6 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
AirTAC no longer produces the ACPD family. The current direct is the ACED12X5 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class. Before swapping, confirm the ISO 21287 mounting dimensions against your fixture, since the ACP was built to a DIN-standard face.
