This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X120B, 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 ACPD25X120B
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X120B 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 ACED25X120B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X120B
This is a double acting, double-rod compact cylinder in the discontinued AirTAC ACPD series, with a 25 mm bore and a 120 mm stroke. A 10 mm piston rod exits both covers, so the through-rod gives a symmetric mount, resists rotation and side load, and lets the rear rod carry a sensor flag or a second tool. Because both strokes work on the rod-side area, output is equal in each direction: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa. The body is hard-anodized aluminium with an S45C hard-chrome rod, a fixed TPU bumper at each end, and a male rod thread (the B code) on both rod ends.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and guarding. Note that this model is discontinued: the current-production direct is the ACED25X120, and buyers should confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X120B (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 ACPD25X120B Is Used
Two-sided jig clamping
The through-rod clamps a machined aluminium bracket from both covers at once, applying 206.2 N per side at 0.5 MPa in a drilling fixture.
Bidirectional pusher on a packaging line
Equal force in both strokes lets one cylinder divert small cartons left or right on a conveyor at up to 500 mm/s without a valve change.
Sensor flag carrier in a test station
The rear rod drives a flag past CMSE or DMSE switches (when the optional -S magnet is ordered) to confirm end positions on an automated gauge stand.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X120B with the ACED25X120B
Size the job both ways: the 20 mm bore delivers 117.8 N at 0.5 MPa, while the 32 mm bore reaches 345.6 N, so the 25 mm sits between them at 206.2 N in both directions. The 120 mm stroke is within the 150 mm standard range for this bore, so no made-to-order build is needed. Ports are M5x0.8, and the male rod thread (B code) suits knuckle and tooling attachments. Remember that a plain double-rod cylinder drifts when air is lost - for a held load, add a rod lock or pilot check valve. FA/FB flange and LB foot mountings bolt to the same face. This model is discontinued; order the ACED25X120 as the current replacement and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED25X120B
- ✓ 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 ACPD25X120B FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force 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 pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 120 mm stroke sits inside the 150 mm standard limit for the 25 mm bore.
This model is no longer in production. The current direct is the ACED25X120 (swap the P for an E), which matches the same bore, stroke and force class; confirm the ISO 21287 mounting dimensions before swapping because the ACP is DIN-standard. For switching, the magnet is not fitted on this code - it comes only with the optional -S version, which accepts CMSE and DMSE reed or solid-state switches.
