This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X40, 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 ACPD25X40
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X40 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm 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 ACED25X40 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X40
The ACPD25X40 is a double acting compact cylinder with a double rod: a 10 mm piston rod exits both covers of the hard-anodized aluminium body, so the 25 mm bore delivers the same 206.2 N at 0.5 MPa (288.6 N at 0.7 MPa) whether it pushes or pulls. The through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at both ends and speed runs 30-500 mm/s.
Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarding. Note this model is discontinued: the current-production replacement is the ACED25X40, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X40 (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 ACPD25X40 Is Used
Two-sided jig clamping
The through-rod lets a fixture plate clamp from both covers at 206.2 N each way, ideal for a 40 mm-stroke machining jig on a CNC line.
Reciprocating slide drive
Equal force in both directions drives a small pick-and-place slide back and forth at 30-500 mm/s without a pull-force penalty.
Rear-rod flag sensing
With the optional -S magnet, the back rod carries a flag past a CMSE or DMSE switch to confirm retract on an assembly station.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X40 with the ACED25X40
At 206.2 N per direction, the 25 mm bore sits between the 20 mm (117.8 N) and 32 mm (345.6 N) double-rod sizes; step up to 32 mm if your fixture needs margin, or down to 20 mm for lighter tooling. The 40 mm stroke is well inside the 150 mm standard limit for this bore. This unit has a female M6x1.0 rod thread, PT ports and no magnet - order the -S code if you need CMSE or DMSE switches. Since ACPD is discontinued, specify the ACED25X40 as the direct successor and verify the ISO 21287 mounting footprint. For loads that must stay put on air loss, add a rod lock or pilot check - the bare cylinder will drift.
Replacement checklist
- ✓ Current-production ACE → ACED25X40
- ✓ 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 ACPD25X40 FAQ
Because a rod exits both covers, force is equal in both directions: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, with a peak 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), and speed 30-500 mm/s. The bore is 25 mm, stroke 40 mm, rod 10 mm, port M5x0.8, rod thread M6x1.0 female.
No - the ACPD family is discontinued. The current-production direct is the ACED25X40 (swap the P for an E), which matches the same bore, stroke and force class in the ISO 21287 short-body format. Confirm the ISO 21287 mounting dimensions against your fixture before ordering, and add the -S magnet code on the replacement if you use CMSE or DMSE switches.
