This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X90S, 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 ACPD25X90S
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X90S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 90mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X90S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X90S
This is a double acting, double-rod compact cylinder: a piston rod exits both covers of the hard-anodized aluminium body, 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, because both sides work on the rod-side area. The 90 mm stroke sits well inside the 150 mm standard range for this bore, and the through-rod resists rotation and side load while giving a symmetric mount. The S code means the optional magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the tube.
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, guards and gantries. A fixed TPU bumper sits at both ends, the S45C hard-chrome rod runs at 30-500 mm/s on air filtered to 40 um, and pressure spans 0.15-1.0 MPa (22-145 psi). Note that ACPD is discontinued: the current direct is ACED25X90, so confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X90S (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 ACPD25X90S Is Used
Twin-side ejection in a jig
The through-rod lets a press-out tip work from both covers on a 90 mm stroke, with 206.2 N at 0.5 MPa available in either direction for pushing parts out of a drilling fixture.
Position feedback on a gantry
Because the -S magnet is fitted, CMSE or DMSE switches clamp onto the tube to signal end positions of a 25 mm bore slide moving at 30-500 mm/s, no extra flag needed on the rear rod.
Synchronized transfer heads
Equal force both ways makes the double rod ideal for a push-pull transfer station on an electronics assembly line, where the back-end rod carries a guide or sensor flag through the same 90 mm travel.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X90S with the ACED25X90S
Size both ways: if 206.2 N at 0.5 MPa is more than your fixture needs, the 20 mm bore gives 117.8 N with the same M5x0.8 port; if you need headroom, step up to the 32 mm bore for 345.6 N at 0.5 MPa. Remember a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. This unit already carries the -S magnet for CMSE / DMSE switches; FA/FB flange, LB foot and CA/CB clevis brackets bolt to the same face. For new builds order the ACED25X90, the current-production successor in the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACED25X90S
- ✓ 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 ACPD25X90S FAQ
Both directions are identical because the rod-side area is the same on each side of the piston: 206.2 N at 0.5 MPa, 288.6 N at 0.7 MPa, and a maximum of 42.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
The ACPD family is no longer in production. The current direct is the ISO 21287 ACED25X90, which matches the same 25 mm bore, 90 mm stroke and force class with the same short body and mounting family. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to a DIN standard.
