This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X90, 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 ACPD25X90
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X90 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 ACED25X90 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X90
Double acting with a rod leaving both covers, the ACPD25X90 pushes and pulls with identical force because each stroke works on the rod-side area: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in either direction. The through-rod resists rotation and light side load, gives a symmetric mounting face, and lets the rear rod carry a sensor flag on a packaging or assembly jig. A fixed TPU bumper sits at each end, and speed spans 30-500 mm/s.
This 25 mm model is discontinued; the current-production direct is the ISO 21287 ACED25X90 in the same bore, stroke and force class, so confirm mounting dimensions before swapping. The short body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight gantries. Plan on about 124 N of usable work at 0.5 MPa - roughly 12 kg of real vertical capacity with a margin - rather than the full rating. The optional -S magnet enables CMSE / DMSE switches; this code has none fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X90 (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 ACPD25X90 Is Used
Reciprocating transfer arm
The through-rod drives a parts carrier on a small electronics assembly line, pushing 206.2 N in both directions so the return stroke lifts the carrier as briskly as the forward stroke at 0.5 MPa.
Clamp and unclamp fixture
On a CNC jig for aluminium brackets, the front rod clamps the part while the rear rod trips a proximity flag, giving 288.6 N of clamping force at 0.7 MPa from a body short enough for the fixture plate.
Two-position gate on a filler
A bottling line gate slides on the 90 mm stroke; with the -S magnet ordered, CMSE or DMSE switches confirm each end position, and the TPU bumpers quiet the reversal.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X90 with the ACED25X90
At 206.2 N per side at 0.5 MPa, the 25 mm bore suits clamping and transfer tasks up to about 12 kg of vertical load with margin; step down to the 20 mm bore (117.8 N) for lighter gates or up to 32 mm (345.6 N) for heavier fixtures. The 90 mm stroke sits inside the 150 mm standard range for this bore. Female M6x1.0 rod thread, PT ports, FA/FB flange or LB foot mounts. It does not hold position if air is lost - add a rod lock or pilot check for a suspended load. Order ACED25X90 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED25X90
- ✓ 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 ACPD25X90 FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal both ways: 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 range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
Order the ACED25X90, the current ISO 21287 successor: swap the P for an E and you keep the same 25 mm bore, 90 mm stroke and force class, but confirm the mounting dimensions first since ACP is DIN-standard. For sensing on either cylinder, the magnet is the optional -S code - without it no CMSE or DMSE switch can be mounted, so specify -S when ordering.
