This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X20S, 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 ACPD25X20S
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X20S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X20S
Double acting with a rod exiting both covers, the ACPD25X20S is a DIN-standard compact cylinder whose 25 mm bore delivers an equal 206.2 N in each direction at 0.5 MPa (288.6 N at 0.7 MPa), because both strokes work on the rod-side area. The through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag, while fixed TPU bumpers sit at both ends. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), from -20 to +70 C at 30-500 mm/s.
The hard-anodized aluminium body with an S45C hard-chrome rod keeps the ISO 21287 short build, which saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. This model carries the optional -S magnet, so CMSE / DMSE switches can be mounted for position feedback. Note that ACPD is discontinued: the current-production direct is the ACED25X20, and you should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X20S (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 ACPD25X20S Is Used
Fixture clamping on CNC jigs
The equal 206.2 N force in both directions clamps and releases a machined aluminium bracket with identical grip, and the 20 mm stroke fits a shallow jig plate.
Position feedback on a pick station
With the -S magnet fitted, CMSE or DMSE switches confirm extend and retract on a small electronics assembly press, using the rear rod as a flag carrier.
Product pusher on a packaging line
The through-rod keeps the pusher bar square under side load as it nudges cartons sideways, at about 12 kg vertical-lift equivalent with margin.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X20S with the ACED25X20S
At 206.2 N per side (0.5 MPa), the 25 mm bore suits clamping and positioning where a 16 mm bore (75.4 N) is too light but a 32 mm bore (345.6 N) adds bulk you do not need. The 20 mm stroke is well inside the 150 mm maximum standard stroke for this bore. Remember the piston drifts when air is lost, so use a rod lock or pilot check if a load must be held. FA/FB flange or LB foot mounting bolts to the ISO 21287 face, and this -S version accepts CMSE / DMSE switches. For new projects, order the ACED25X20 instead, as ACPD is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACED25X20S
- ✓ 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 ACPD25X20S 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, with a maximum of 42.0 kgf at 1.0 MPa. Both strokes use the rod-side area, so push and pull are identical. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and an M5x0.8 port. The ACPD25X20S is discontinued; the current direct is the ACED25X20 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
