This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X25B, 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 ACPD12X25B
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X25B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X25B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X25B
This is a double acting compact cylinder with a rod leaving both covers, so the 12 mm bore delivers an identical 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. The through-rod resists rotation and side load, gives a symmetric mount, and lets the rear rod carry a sensor flag or a second tool. Stroke is 25 mm, the male-threaded rod end (B code) is 6 mm with M6x1 female thread, and the air port is M5x0.8.
The hard-anodized aluminium body with an S45C hard-chrome rod saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and small guarding. A fixed TPU bumper sits at each end, speed runs 30-500 mm/s, and pressure spans 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating. Plan on about 25 N (roughly 2.6 kg of vertical lift with margin) as the practical working force rather than the full rating. Note: this model is discontinued; the current direct is ACED12X25, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X25B (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 ACPD12X25B Is Used
Micro press fixture
The symmetric 42.4 N push and pull at 0.5 MPa seats small connectors in an electronics assembly jig, with the 25 mm stroke matching shallow die depth.
Flag carrier on a tester
The rear rod drives a sensor flag past a photoeye on a semiconductor test bench, giving position feedback without extra hardware.
Push-pull gate on a sorter
Equal force both ways nudges small packages between conveyor lanes in a compact sorting head where a full-length body would not fit.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X25B with the ACED12X25B
At 42.4 N per direction this 12 mm bore suits light clamping, sorting and small part transfer; step up to the 16 mm bore (75.4 N) or drop to a single-rod ACP if you need more or asymmetric force. The through-rod keeps the piston stable under slight side load, but the cylinder will not hold position if air is lost - add a rod lock or pilot check for a held load. No magnet is fitted on this code; order the -S version if you need CMSE / DMSE switch positions. Replacement: ACED12X25.
Replacement checklist
- ✓ Current-production ACE → ACED12X25B
- ✓ 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 ACPD12X25B FAQ
Output is equal both ways because a rod exits each cover and both strokes use the rod-side area: 42.4 N at 0.5 MPa, 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), speed 30-500 mm/s, and the rod end is male thread on a 6 mm rod.
The ISO 21287 class short body with hard-anodized aluminium construction saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange or LB foot mounting and a fixed TPU bumper at each end. The ACPD is discontinued; the current-production direct is ACED12X25 - confirm the ISO 21287 mounting dimensions before swapping.
