This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X30, 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 ACPD20X30
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X30 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 30mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X30 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X30
This double acting compact cylinder carries a rod out of both covers, so the 20 mm bore delivers the same 117.8 N at 0.5 MPa (164.9 N at 0.7 MPa) whether the piston moves forward or back. The through-rod resists rotation and side load, gives a symmetric mounting face, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end and the body runs at 30-500 mm/s.
The hard-anodized aluminium body follows the ISO 21287 short format, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and gantries. Note this model is discontinued: the current-production direct is the ACED20X30, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X30 (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 ACPD20X30 Is Used
Fixture clamping
Clamps small machined brackets in a drilling jig with 117.8 N of equal holding force on both the clamp and release stroke.
Push-pull indexing
The through-rod drives a slide both ways at identical force, indexing parts between two stations on a light assembly line.
Sensor flag carrier
The rear rod carries a flag for a proximity switch, giving end-of-stroke confirmation on a pick-and-place gantry.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X30 with the ACED20X30
At 117.8 N per side, bore 20 suits light clamping and transfer where a smaller 16 mm bore (75.4 N) is marginal but a 25 mm bore (206.2 N) is oversized. The 30 mm stroke sits well inside the 100 mm standard limit for this bore. Because the piston drifts when air is lost, add a rod lock or pilot check if the load must stay put. FA/FB flange and LB foot mountings bolt to the ISO 21287 face; for position sensing order the -S code, since without it no magnet is fitted and CMSE / DMSE switches cannot be used. Replacement is the ACED20X30.
Replacement checklist
- ✓ Current-production ACE → ACED20X30
- ✓ 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 ACPD20X30 FAQ
Because a rod exits both covers, both strokes use the rod-side area and the force is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa. At the full 1.0 MPa rating the bore reaches about 24 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed spans 30-500 mm/s.
The ISO 21287 format body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits compact guards and slides. The fixed TPU pad at each end only decelerates the piston at the ends of travel and never holds or brakes a load. FA/FB flange and LB foot options mount to the standard face, and the optional -S magnet enables CMSE / DMSE switches. This model is discontinued; the ACED20X30 is the current direct.
