This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X70S, 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 ACPD25X70S
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X70S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X70S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X70S
A double acting compact cylinder with a rod through BOTH covers, the ACPD25X70S pushes and pulls with identical output 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 25 mm bore carries the optional -S magnet on this code, so CMSE or DMSE reed and solid-state switches can be clipped straight onto the hard-anodized aluminium body. The through-rod resists rotation and side load, and the rear rod is a handy mounting point for a sensor flag.
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 gantries. Note this model is discontinued: the current direct is ACED25X70, same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X70S (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 ACPD25X70S Is Used
Reciprocating parts transfer
The through-rod drives a sliding carrier on a small assembly line, delivering 206.2 N in both directions so the return stroke pushes parts off a nest at the same speed, 30-500 mm/s.
Position-flagged test fixture
With the fitted -S magnet, a DMSE switch on the body confirms end-of-stroke on a 70 mm go/no-go gauge, while the rear rod carries the flag for the second position.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X70S with the ACED25X70S
For a 70 mm stroke needing equal force both ways, this 25 mm double-rod unit delivers 206.2 N at 0.5 MPa; step down to a 20 mm bore (117.8 N) for lighter clamping or up to 32 mm (345.6 N) for heavier tooling. The piston drifts when air is lost, so add a rod lock or pilot check if the load must stay put. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. Order ACED25X70 as the current-production replacement.
Replacement checklist
- ✓ Current-production ACE → ACED25X70S
- ✓ 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 ACPD25X70S FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal either way: 206.2 N at 0.5 MPa and 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 pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, and the fixed TPU bumper at each end only decelerates the piston - it never holds or brakes a load.
The ACPD family is no longer in production. The current direct is ACED25X70 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class with the same FA/FB flange and LB foot mounting family. Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping. The -S magnet code and CMSE / DMSE switch options carry over.
