This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X25B, 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 ACPD20X25B
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X25B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X25B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X25B
Double acting with a rod leaving both covers, the ACPD20X25B pushes and pulls with identical force because each stroke works on the rod-side area: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa in either direction. The 10 mm through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end, and the short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder.
This model is discontinued. The current-production direct is the ACED20X25, which keeps the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping. The optional -S magnet enables CMSE / DMSE switches; without it no sensor can be fitted. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X25B (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 (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 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 ACPD20X25B Is Used
Fixture clamping on small CNC jigs
The 25 mm stroke and about 70 N of usable thrust at 0.5 MPa clamp brackets or housings in a jig, and the through-rod lets a clamp arm ride on either end.
Flag carrier for position sensing
With the optional -S magnet ordered, CMSE or DMSE switches read position on the 20 mm bore body while the rear rod drives a separate indicator flag.
Push-off on compact packaging heads
Equal 117.8 N force in both directions ejects cartons or blisters from a tight packaging station where a full-length cylinder cannot fit.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X25B with the ACED20X25B
At 117.8 N per side at 0.5 MPa, bore 20 suits light clamping and transfer. Step down to bore 16 (75.4 N) for tighter spaces, or up to bore 25 (206.2 N) when the load grows. The plain piston drifts when air is lost, so add a rod lock or pilot check for a held load. FA/FB flange or LB foot mounting bolts to the standard face, and order the -S code if CMSE / DMSE switching is needed. For new projects, specify the ACED20X25 instead.
Replacement checklist
- ✓ Current-production ACE → ACED20X25B
- ✓ 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 ACPD20X25B FAQ
Because a rod exits both covers, force is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, with a peak of 24.0 kgf at 1.0 MPa. Pressure range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, male rod thread (B code).
The model is discontinued; the current direct is the ACED20X25 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. Position sensing requires the optional -S magnet at order time, which then accepts CMSE / DMSE switches; without -S there is no magnet.
