This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X125B, 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 ACPD25X125B
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X125B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 125mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X125B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X125B
Double acting with a rod leaving both covers, the ACPD25X125B pushes and pulls with the same 206.2 N at 0.5 MPa (288.6 N at 0.7 MPa) because both strokes work on the rod-side area. The 25 mm bore and 125 mm stroke suit compact slides and symmetric fixtures, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air.
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. A fixed TPU bumper pads each end, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the B code gives a male rod thread. Note: this model is discontinued; the current direct is ACED25X125, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X125B (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 ACPD25X125B Is Used
Symmetric jig clamping
The male-threaded through-rod lets a fixture clamp from both sides of a 125 mm slide with equal 206.2 N force in each direction at 0.5 MPa.
Pusher on a packaging line
About 12 kg of vertical-lift equivalent at 0.5 MPa suits diverting small cartons, with the fixed TPU bumper decelerating the 30-500 mm/s stroke at each end.
Flag-driven position check
The rear rod carries a sensor flag on a test bench; order the -S variant for CMSE / DMSE switch compatibility, since this non-S unit has no magnet.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X125B with the ACED25X125B
At 206.2 N per side, bore 25 sits between bore 20 (117.8 N) and bore 32 (345.6 N) at 0.5 MPa, so step up to 32 mm if your tooling weight grows. The 125 mm stroke is within the 150 mm standard limit for this bore. If the load must stay put when air is lost, add a rod lock or pilot check - a plain double-rod cylinder will drift. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and the optional -S code enables CMSE / DMSE switches; this unit has no magnet fitted. Order ACED25X125 as the current-production replacement.
Replacement checklist
- ✓ Current-production ACE → ACED25X125B
- ✓ 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 ACPD25X125B FAQ
Because it is a double-rod cylinder, force is equal in both directions: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa on the rod-side area, with a maximum of 42.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) and proof pressure is 1.5 MPa (215 psi).
This model is discontinued. The ACED25X125 is the current ISO 21287 successor in the same bore, stroke and force class, with a short body roughly 50% shorter than an ISO 15552 profile cylinder. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint.
