This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X5S, 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 ACPD25X5S
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X5S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm 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 ACED25X5S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X5S
Double acting with a rod leaving both covers, the ACPD25X5S pushes with equal force in each direction - 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa either way, because both strokes work on the rod-side area. This 25 mm bore unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke detection over a 5 mm stroke. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight fixtures a full-length body cannot reach.
The through-rod resists rotation and modest side load and gives a symmetric mount, and the rear rod can carry a sensor flag in pick-and-place heads. A fixed TPU bumper sits at each end to soften the approach. Note this model is discontinued: the current-production direct is the ACED25X5, so confirm ISO 21287 mounting dimensions before swapping, since the ACP follows the DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X5S (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 (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 ACPD25X5S Is Used
PCB test fixture clamping
The 5 mm stroke and 206.2 N force at 0.5 MPa are enough to press a small electronics board against locating pins in an in-circuit test nest, with the through-rod keeping the clamp plate square.
Small-part ejection from a die
A short kick of about 21 kgf equivalent clears a finished brass fitting off a forming station; the rear rod can carry a flag for a DMSE switch to confirm ejection.
Lab sampler actuation
A vial pusher in an analytical sampler needs only a few millimetres of travel; the symmetric double-rod mount lets the mechanism be driven from either end of the cylinder.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X5S with the ACED25X5S
At 5 mm stroke this is a short-throw actuator for clamping or indexing a few millimetres. If 206.2 N at 0.5 MPa is marginal, step up to the 32 mm bore (345.6 N); if the load is light, the 20 mm bore at 117.8 N saves space. Like any plain double-rod cylinder it drifts when air is lost, so add a rod lock or pilot check for a held load. FA/FB flange and LB foot mountings bolt to the standard face, and the -S magnet on this unit pairs with CMSE / DMSE switches. For new designs, order the ACED25X5 instead - same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACED25X5S
- ✓ 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 ACPD25X5S FAQ
Because it is a double-rod cylinder, output is equal both ways: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in each direction, with a maximum of 42.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the air must be filtered to 40 um. The rod is 10 mm with an M6x1.0 female thread, and the port is M5x0.8.
No - the ACPD family is discontinued. The current-production replacement is the ACED25X5, the ISO 21287 version with the same 25 mm bore, 5 mm stroke and force class. Since the ACP was built to the DIN standard, confirm the ISO 21287 mounting dimensions before swapping. The -S magnet code carries over, so CMSE / DMSE switches remain available on the replacement.
