This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X20, 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 ACPD25X20
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X20 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X20 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X20
Double acting with a rod leaving both covers, the ACPD25X20 pushes and pulls with identical force: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in each direction, because both strokes work on the rod-side area. The 25 mm bore, 20 mm stroke and 10 mm through-rod suit short, symmetric strokes where a fixture plate or sensor flag rides the rear rod. The hard-anodized aluminium body keeps the ISO 21287 short profile, roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding.
The fixed TPU bumper at each end decelerates the piston only; it never holds position, so a lost-air load will drift unless you add a rod lock or pilot check. This model is discontinued: the current direct is ACED25X20, same bore, stroke and force class, but confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X20 (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 ACPD25X20 Is Used
Symmetric jig clamping
The 206.2 N equal push and pull clamps a machined aluminium bracket in a drilling fixture and releases with the same force, with the 20 mm stroke clearing the part quickly.
Rear-rod flag position check
The through-rod carries a flag on the back cover so a PLC can confirm full retraction of a 20 mm gate on a packaging line, using the optional -S magnet with CMSE switches.
Compact press assist
About 12 kg of vertical force at 0.5 MPa is enough to seat small rubber grommets in an electronics assembly cell where a full-length cylinder will not fit under the gantry.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X20 with the ACED25X20
At 206.2 N per side at 0.5 MPa, bore 25 sits between the 16 mm bore (75.4 N) and the 32 mm bore (345.6 N); step down for light pick-and-place, up if the load needs more margin. The 20 mm stroke is well inside the 150 mm standard limit for this bore. Rod end is female M6x1.0 with a PT port; FA/FB flange or LB foot mounts bolt to the ISO 21287 face. No magnet is fitted on this code, so CMSE or DMSE switches cannot be used unless you order the -S variant. For new builds, order ACED25X20 instead.
Replacement checklist
- ✓ Current-production ACE → ACED25X20
- ✓ 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 ACPD25X20 FAQ
Because a rod exits both covers, force is equal both ways: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa on every stroke, 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 port is M5x0.8 with a female M6x1.0 rod thread.
The hard-anodized aluminium body follows the short ISO 21287 format, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange and LB foot options. The ACPD25X20 is discontinued; the current-production replacement is ACED25X20 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
