This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X65B, 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 ACPD25X65B
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X65B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 65mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X65B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X65B
A double acting compact cylinder with a rod leaving both covers, the ACPD25X65B pushes 206.2 N in each direction at 0.5 MPa because both strokes work on the rod-side area of the 25 mm bore. The 65 mm stroke sits well inside the 150 mm standard range for this bore, and the male rod thread (B code) bolts straight to your tooling. The hard-anodized aluminium body is an ISO 21287 short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding.
The through-rod resists rotation and side load and gives a symmetric mount, while the rear rod can carry a sensor flag on a fixture. Fixed TPU bumpers sit at both ends and the rod runs 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). Note this model is discontinued: the current-production direct is the ACED25X65, so confirm the ISO 21287 mounting dimensions before you swap.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X65B (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 ACPD25X65B Is Used
Symmetric jig clamping
The 206.2 N equal force in both directions lets one ACPD25X65B clamp and release a machined aluminium bracket in a drilling fixture with identical pressure each way.
Reciprocating slide drive
A 65 mm stroke driving a small parts shuttle between two pick points on an assembly bench, with the rear rod carrying a flag for a proximity sensor.
Push-off at carton seal
Kicking filled 10 kg cartons off a sealing conveyor end-stop, where the 65 mm stroke clears the lane and the through-rod handles light side load.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X65B with the ACED25X65B
Size both ways before committing: the 20 mm bore gives 117.8 N at 0.5 MPa if your load is lighter, while the 32 mm bore delivers 345.6 N if you need more margin. Remember that a plain double-rod cylinder 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 ISO 21287 face, and if you later want position sensing, order the -S code to enable CMSE / DMSE switches - this B-coded model has no magnet fitted. For new designs, specify the ACED25X65 instead, as the ACPD line is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACED25X65B
- ✓ 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 ACPD25X65B FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal either way: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, with a maximum of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 65 mm stroke is within the 150 mm standard limit for the 25 mm bore.
Order the ACED25X65, the current-production ISO 21287 successor: swap the P for an E and you get the same bore, stroke and force class in a matching short body. Because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping. If you need switches on the replacement, remember the magnet is the optional -S code, enabling CMSE / DMSE sensors.
