This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X45, 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 ACPD25X45
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X45 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 45mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X45 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X45
This AirTAC ACPD25X45 is a double acting compact cylinder with a rod leaving both covers, so the 25 mm bore delivers the same 206.2 N at 0.5 MPa on every stroke - the rod-side area works in both directions. The through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end, and the short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit.
The hard-anodized aluminium body carries an S45C hard-chrome rod, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) and moves at 30-500 mm/s. At 0.7 MPa the output is 288.6 N in either direction. Note this model is discontinued: the current-production replacement is the ACED25X45, a direct successor in the same bore, stroke and force class, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X45 (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).

Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
Where the Airtac ACPD Double Rod Compact Cylinder ACPD25X45 Is Used
Two-sided jig clamping
The through-rod lets a fixture plate clamp on the front rod while the rear rod drives a position flag, with 206.2 N of equal clamping force each way at 0.5 MPa.
Symmetric slide actuation in test rigs
The double rod resists rotation and side load, and ordering the optional -S magnet allows CMSE / DMSE switches for end-of-stroke detection on both covers.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X45 with the ACED25X45
For a 45 mm stroke with equal force both ways, the 25 mm bore gives 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa. If your load needs less, the 20 mm bore offers 117.8 N at 0.5 MPa; if you need more, step up to the 32 mm bore at 345.6 N. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. Mounting brackets (FA/FB flange, LB foot, CA/CB clevis) bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches - without the -S code there is no magnet at all. This unit is discontinued; order the ACED25X45 as the current direct and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED25X45
- ✓ 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 ACPD25X45 FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area. Output is 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in either direction, with a maximum of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, port M5x1.0? no - M5x0.8, female rod thread M6x1.0.
AirTAC no longer produces the ACPD family. The current-production replacement is the ACED25X45 (swap the P for an E), an ISO 21287 compact double-rod cylinder in the same bore, stroke and force class. Before swapping, confirm the ISO 21287 mounting dimensions, since the ACP was built to a DIN-standard footprint.
