This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X125, 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 ACPD20X125
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X125 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm 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 ACED20X125 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X125
A double acting compact cylinder with a rod leaving both covers, the ACPD20X125 delivers the same 117.8 N at 0.5 MPa on every stroke because both sides work on the rod-side area. The through-rod resists rotation and side load, gives a symmetric mounting face, and the rear rod can carry a sensor flag. Its 125 mm stroke is longer than the 100 mm standard for a 20 mm bore, so it is made to order. This model is discontinued; the current-production direct is the ISO 21287 ACED20X125.
The hard-anodized aluminium body is an ISO 21287 short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and gantry arms. A fixed TPU bumper sits at each end, the S45C hard-chrome rod runs on a two-way grease-storing seal, and speed spans 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). No magnet is fitted; order the -S code to enable CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X125 (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 ACPD20X125 Is Used
Two-sided jig clamping
The 117.8 N rod-side force on both strokes lets one cylinder clamp a machined aluminium bracket from either end in a drilling fixture, with the through-rod keeping alignment true.
Push-pull slide transfer
A packaging line slide that must move a 6 kg tray out and back at equal speed uses the symmetric 117.8 N output at 0.5 MPa, running well inside the 30-500 mm/s band.
Flag-driven position check
On a small assembly gantry, the rear rod carries a flag for a CMSE or DMSE switch (ordered with the -S magnet code) to confirm retraction before the next cycle starts.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X125 with the ACED20X125
At 117.8 N per side at 0.5 MPa, this 20 mm bore suits light clamping and transfer work; step down to the 16 mm bore (75.4 N) for smaller loads or up to the 25 mm bore (206.2 N) when you need more force. Remember it drifts when air is lost, so add a rod lock or pilot check for a held load. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches. Since ACPD is discontinued, confirm ISO 21287 dimensions and order the ACED20X125 instead.
Replacement checklist
- ✓ Current-production ACE → ACED20X125
- ✓ 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 ACPD20X125 FAQ
Because a rod exits both covers, output is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa on every stroke, with a maximum of 24.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
No. The 20 mm bore tops out at a 100 mm standard stroke, so 125 mm is a made-to-order length. The ACPD family is discontinued; the ACED20X125 is the current ISO 21287 direct in the same bore, stroke and force class - confirm the mounting dimensions before swapping.
