This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X40, 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 ACPD20X40
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X40 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X40 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X40
The ACPD20X40 is a double acting, double-rod compact cylinder on the DIN-standard ACP platform: a 20 mm bore with a 40 mm stroke, a 10 mm rod exiting both covers, and an M5x0.8 air port. Because both strokes work on the rod-side area, output is identical in each direction - 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa. The through-rod resists rotation and side load, gives a symmetric mounting face, and leaves a free rod end at the rear for a sensor flag. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
This model is discontinued; the current-production successor is the ACED20X40 (swap the P for an E), which matches the same bore, stroke and force class on the ISO 21287 short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard. The optional -S magnet enables CMSE / DMSE switches; without it no magnet is fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X40 (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 ACPD20X40 Is Used
Bidirectional part transfer
The through-rod pushes and pulls with equal 117.8 N force at 0.5 MPa, ideal for a shuttle table on a small electronics assembly station that must index parts both ways.
Rear-rod sensor flag
The second rod at the back cover carries a cam flag for a proximity switch on a packaging machine, giving position feedback without loading the working stroke.
Compact press fixture
With about 70 N of usable working force and a short 40 mm stroke, it suits a light staking or marking jig inside a tight fixture where a full-length profile cylinder will not fit.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X40 with the ACED20X40
At 20 mm bore the ACPD20X40 delivers 117.8 N both ways at 0.5 MPa - step down to a 16 mm bore (75.4 N) for lighter tooling or up to 25 mm (206.2 N) when the job needs more push. Note that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay put. FA/FB flange and LB foot mounts bolt to the standard face, and the optional -S magnet supports CMSE / DMSE switches. Order the ACED20X40 as the current direct replacement.
Replacement checklist
- ✓ Current-production ACE → ACED20X40
- ✓ 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 ACPD20X40 FAQ
Yes - as a double-rod cylinder both strokes use the rod-side area, so force is equal each way: 117.8 N at 0.5 MPa, 164.9 N at 0.7 MPa, and a maximum of 24.0 kgf at 1.0 MPa. Pressure range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, speed 30-500 mm/s, and a fixed TPU bumper at both ends.
Order the ACED20X40, the ISO 21287 successor made by swapping the P for an E. It matches the same 20 mm bore, 40 mm stroke and force class with a short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard, and remember the -S magnet option if you need CMSE / DMSE switch sensing.
