This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X5B, 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 ACPD25X5B
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X5B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X5B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X5B
A double acting, double-rod compact cylinder built to the DIN-standard ACP format: a hard-anodized aluminium body with aluminium covers threaded on, an S45C hard-chrome piston rod and a fixed TPU bumper at each end. Because a rod leaves both covers, the 25 mm bore delivers the same 206.2 N at 0.5 MPa (288.6 N at 0.7 MPa) on every stroke, so the back-end rod can drive a second tool or carry a sensor flag while the front rod does the work. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into cramped fixture plates and guard rails.
Speed range is 30-500 mm/s, air must be filtered to 40 um, and pressure runs 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof limit. Note that this model is discontinued; the current-production direct is the ACED25X5 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X5B (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 ACPD25X5B Is Used
PCB test fixture clamping
The 5 mm stroke and 206.2 N per side at 0.5 MPa are enough to seat a board into a pogo-pin nest and retract it in one quick motion at up to 500 mm/s.
Indexing pin on a rotary dial table
A short-throw through-rod pushes an indexing pin in and pulls it back with equal 288.6 N at 0.7 MPa, and the rear rod can carry a cam or flag for a proximity sensor.
Carton flap kickers on a packing line
The 25 mm double-rod body flips small flaps or tabs with identical force in both directions, and the compact body fits the tight envelope beside the sealing head.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X5B with the ACED25X5B
For a 5 mm nudge or clamp job in the 200 N class, the 25 mm bore gives 206.2 N both ways at 0.5 MPa; if your load is lighter, the 20 mm bore still supplies 117.8 N at the same pressure, and stepping up to 32 mm buys 345.6 N. The rod ends in a male thread (the B code), and the port is M5x0.8. FA/FB flange and LB foot mounts bolt to the standard face, and CMSE or DMSE switches can be used only if you order the optional -S magnet - this unit has no magnet fitted. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay put. Order the ACED25X5 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED25X5B
- ✓ 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 ACPD25X5B FAQ
It is double acting with a rod on both covers, so force is equal both ways: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa on every stroke, with a maximum of 42.0 kgf at 1.0 MPa. Both strokes use the rod-side area, so there is no push-versus-pull difference. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed runs 30-500 mm/s.
The short ISO 21287-class body saves 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 ACED25X5 (same 25 mm bore, 5 mm stroke and force class). Confirm the ISO 21287 mounting dimensions before you swap, because the ACP is DIN-standard.
