This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X40S, 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 ACPD25X40S
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X40S 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 ACED25X40S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X40S
A double acting, double-rod compact cylinder built to the DIN-standard ACP pattern, the ACPD25X40S pushes and pulls with identical force because a 10 mm rod exits both covers and every stroke works on the rod-side area. At 0.5 MPa that is 206.2 N in each direction, rising to 288.6 N at 0.7 MPa. The 40 mm stroke sits well inside the 150 mm standard range for the 25 mm bore, and the S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs, guards and gantries. The through-rod resists rotation and light side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at both ends. Note this model is discontinued: the current-production direct is ACED25X40, and you should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X40S (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 ACPD25X40S Is Used
Symmetric push-pull transfer on small automation
The through-rod lets a fixture clamp or eject from either side with the same 206.2 N at 0.5 MPa, ideal for benchtop pick-and-place heads on electronics assembly lines.
Position-checked test stations
With the fitted -S magnet driving CMSE or DMSE switches, a 40 mm stroke confirms probe engagement or part seating in QC fixtures before the cycle continues.
Compact press-fit of small components
About 12.6 kg of usable push at 0.5 MPa seats bushings, pins and connectors in jig-built sub-assemblies where the short body must fit inside a guarded module.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X40S with the ACED25X40S
For a 25 mm bore the equal push-pull rating is 206.2 N at 0.5 MPa. If your load needs less, the 20 mm bore gives 117.8 N both ways; if it needs more, step up to the 32 mm bore at 345.6 N. Remember the piston drifts when air is lost - for a held load add a rod lock or pilot check valve. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. Order ACED25X40 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED25X40S
- ✓ 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 ACPD25X40S 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 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 range 30-500 mm/s, and the port is M5x0.8 with an M6x1.0 female rod thread.
No - the ACPD family is discontinued. The current-production direct is ACED25X40 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard pattern.
