This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X30B, 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 ACPD20X30B
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X30B 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 ACED20X30B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X30B
A double acting compact cylinder with a rod leaving both covers, the ACPD20X30B pushes and pulls with identical output because both strokes work on the rod-side area: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa in either direction. The 20 mm bore carries a 10 mm through-rod with a male thread at each end (the B code), and the fixed TPU bumper sits at both covers. Note that this model is discontinued; the current-production successor is ACED20X30.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarding where a full-length body cannot fit. The through-rod also resists rotation and side load, and the rear rod can carry a sensor flag. Running spec: air filtered to 40 um, 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, -20 to +70 C.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X30B (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 ACPD20X30B Is Used
Symmetric ejection in a fixture
The 117.8 N equal push and pull at 0.5 MPa lets one 30 mm stroke both seat and retract a locating pin in a machining fixture without changing pressure between directions.
Dual-flag position checking
With a rod at each cover, a PLC can read both end positions from flags on the two rod ends - add the -S magnet code to enable CMSE or DMSE switches.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X30B with the ACED20X30B
At 117.8 N per side at 0.5 MPa, this 20 mm bore sits between the 16 mm bore (75.4 N) and the 25 mm bore (206.2 N), so step up to 25 mm if your jig needs more margin. The male rod thread on both ends suits knuckle or threaded-fitting attachments directly. FA/FB flange and LB foot mountings bolt to the standard face, and CMSE or DMSE switches work only if you order the -S magnet code - this unit has no magnet fitted. Since ACPD is discontinued, order ACED20X30 as the direct and confirm the ISO 21287 mounting dimensions before swapping, as the ACP is DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ACED20X30B
- ✓ 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 ACPD20X30B FAQ
Because it is a double-rod cylinder, force is identical in both directions: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, with a maximum of 24.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s. Remember it does not hold position if air is lost - use a rod lock or pilot check for a held load.
AirTAC no longer produces the ACPD family. The current direct is ACED20X30 (swap the P for an E), which matches the same 20 mm bore, 30 mm stroke and force class in the ISO 21287 short-body format. Before ordering, confirm the ISO 21287 mounting dimensions against your fixture, since the ACP was built to the DIN standard. The ACED keeps the FA/FB flange and LB foot mounting family and accepts the same optional -S magnet for CMSE / DMSE switches.
