This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X120, 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 ACPD25X120
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X120 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 120mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X120 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X120
A double acting compact cylinder with a through rod, the ACPD25X120 pushes a 25 mm piston over a 120 mm stroke and delivers 206.2 N in EACH direction at 0.5 MPa, because a rod exits both covers and both strokes work on the rod-side area. At 0.7 MPa that rises to 288.6 N either way. The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so it slots into tight jigs and gantries.
The through rod resists rotation and light side load, and the rear rod can carry a sensor flag or a second tool. A fixed TPU bumper sits at both ends. Note this model is DISCONTINUED - the current-production direct is the ISO 21287 ACED25X120, so confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X120 (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 ACPD25X120 Is Used
Symmetric jig clamping
The through rod clamps a machined aluminium bracket from both sides of a drilling fixture with equal 206.2 N force, keeping the part centered without a second cylinder.
Two-sided packaging pusher
On a snack-food line, the front rod pushes trays off a conveyor while the rear rod returns a counterweight, both strokes delivering 288.6 N at 0.7 MPa.
Sensor flag carrier
In an electronics assembly gantry, the back-end rod mounts a flag for CMSE / DMSE switches (requires the optional -S magnet) to confirm mid-stroke position over 120 mm.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X120 with the ACED25X120
At 206.2 N per side (0.5 MPa) this bore suits clamping and transfer tasks in the 10-20 kg range; step down to ACPD20 for 117.8 N or up to ACPD32 for 345.6 N if the load differs. The 120 mm stroke sits inside the 150 mm standard range for bore 25. The plain piston drifts when air is lost, so add a rod lock or pilot check for a held load. This unit has no magnet - order the -S code if you need CMSE / DMSE switch positions. Replacement: ACED25X120.
Replacement checklist
- ✓ Current-production ACE → ACED25X120
- ✓ 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 ACPD25X120 FAQ
Yes - it is a double-rod cylinder, so force is equal both ways: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa per direction (rod-side area on both strokes). Maximum force at 1.0 MPa is 42.0 kgf. 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.
The hard-anodized aluminium body follows the short DIN-standard compact format, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange or LB foot mounting and a fixed TPU bumper at each end. The ACPD family is discontinued; the current direct is the ISO 21287 ACED25X120 - confirm its mounting dimensions before ordering.
