This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X25S, 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 ACPD25X25S
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X25S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X25S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X25S
Double acting and double rod, the ACPD25X25S pushes a 25 mm piston through a 25 mm stroke with a rod leaving both covers, so the force is identical whichever way it moves: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa. The through-rod resists rotation and side load, gives a symmetric mount, and the rear rod is a handy carrier for a sensor flag. This unit carries the optional -S magnet, 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 about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs, guarding and gantry tooling. A fixed TPU bumper sits at each end, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the female M6x1.0 rod thread plus M5x0.8 ports keep plumbing simple. Note that this model is discontinued: the current-production direct is the ACED25X25, and buyers should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X25S (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 ACPD25X25S Is Used
Push-pull gauge checking
A 25 mm stroke with 206.2 N each way seats or retracts a dial-gauge fixture on a CNC inspection bench, and the rear rod drives a limit flag.
Small-part diverting gate
The symmetric through-rod swings a lightweight deflector on a bottling line conveyor, with equal force for divert and return at 30-500 mm/s.
Indexed clamp with position signal
With the -S magnet fitted, CMSE switches confirm clamp and release on an electronics assembly jig, giving PLC feedback in a 25 mm envelope.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X25S with the ACED25X25S
At 25 mm bore you get 206.2 N in both directions at 0.5 MPa; if your fixture needs more, the 32 mm ACPD delivers 345.6 N, and if less will do, the 20 mm bore gives 117.8 N. Stroke 25 mm sits well inside the 150 mm maximum standard stroke for this bore. Because a plain double-rod cylinder drifts when air is lost, add a rod lock or pilot check for held loads. Match FA/FB flange or LB foot mounts and I/Y rod knuckles to the ISO 21287 face, keep the -S magnet if you need CMSE/DMSE switches, and order the ACED25X25 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED25X25S
- ✓ 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 ACPD25X25S FAQ
Yes, equal both ways because a rod exits each cover and both strokes use the rod-side area: 206.2 N at 0.5 MPa, 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 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um.
Order the ACED25X25, the ISO 21287 successor made by swapping the P for an E; it matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before the swap since the ACP is DIN-standard, and remember the magnet is the optional -S code, not a default feature.
