This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X125, 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 ACPD25X125
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X125 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 125mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X125 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X125
This double acting compact cylinder carries a rod through BOTH covers, so the 25 mm bore delivers the same 206.2 N at 0.5 MPa (288.6 N at 0.7 MPa) on every stroke - push and pull are identical because both sides work on the rod-side area. The 125 mm stroke sits inside the 150 mm standard range for this bore, and the through-rod resists rotation and side load while the free back-end rod is a handy mount for a sensor flag. A fixed TPU bumper sits at each end.
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 jigs and gantries. Note this model is discontinued: the current-production direct is ACED25X125, so confirm the ISO 21287 mounting dimensions before you swap. As coded there is no magnet - order the optional -S version if you need CMSE / DMSE switches. Plan on roughly 123 N (about 12 kg) of usable work at 0.5 MPa rather than the full 206.2 N rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X125 (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 ACPD25X125 Is Used
Reciprocating transfer slide
The through-rod gives equal 206.2 N thrust in both directions at 0.5 MPa, ideal for a 125 mm shuttle stroke moving small pallets between two stations on an assembly line.
Dual-end position flagging
With the optional -S magnet and CMSE switches, the exposed rear rod carries a flag so a PLC can confirm both ends of a 125 mm gate or indexing move.
Symmetric press fixture
A packaging machine punch that needs the same 288.6 N at 0.7 MPa on downstroke and return fits the compact short body where a full-length cylinder will not fit.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X125 with the ACED25X125
Choose this 25 mm bore when your job needs equal force both ways and about 206.2 N at 0.5 MPa is enough; step down to the 20 mm bore (117.8 N) for lighter clamps or up to the 32 mm bore (345.6 N) for heavier ones. The 125 mm stroke is within the 150 mm standard limit, so no made-to-order build is needed. Remember the piston drifts if air is lost - add a rod lock or pilot check where a load must stay put. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and the female M6x1.0 rod thread takes standard knuckles. For new projects, order ACED25X125 instead - this ACPD is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACED25X125
- ✓ 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 ACPD25X125 FAQ
Because a rod exits both covers, output is identical in each direction: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, both ways. At the 1.0 MPa maximum the bore reaches about 42 kgf. 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 125 mm stroke is within the 150 mm standard range for bore 25.
The model is no longer in production; the current direct is ACED25X125, which matches the same bore, stroke and force class - just verify the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN standard. Switches were never standard: only the -S code adds the magnet, enabling CMSE / DMSE reed or solid-state switches; this unit as coded has no magnet.
