This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X30S, 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 ACPD20X30S
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X30S 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 ACED20X30S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X30S
A double acting compact cylinder with a rod leaving both covers, the ACPD20X30S delivers 117.8 N in each direction at 0.5 MPa because both strokes work on the rod-side area of the 20 mm bore. The through-rod resists rotation and light side load, and the rear rod can carry a sensor flag, while the fixed TPU bumper at each end simply decelerates the piston. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke detection.
The hard-anodized aluminium body follows the short ISO 21287 class, saving about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s, it suits symmetric push-pull work. The ACPD family is discontinued; the current-production replacement is ACED20X30, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X30S (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 ACPD20X30S Is Used
Push-pull part transfer
The through-rod pushes and pulls with equal 117.8 N force at 0.5 MPa, ideal for sliding small fixtures between two stations on an assembly bench.
Position-flagged indexing
With the -S magnet fitted, CMSE or DMSE switches confirm the 30 mm index stroke on a rotary dial or pick-and-place head.
Compact jig clamping
The short ISO 21287-class body fits inside tight drill-jig guarding where a full-length profile cylinder cannot, with about 70 N of practical clamp force at 0.5 MPa.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X30S with the ACED20X30S
For a 30 mm stroke in this force class, the 16 mm bore gives 75.4 N at 0.5 MPa and the 25 mm bore gives 206.2 N, so pick 20 mm only if 117.8 N both ways covers the job. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must be held. FA/FB flange or LB foot mounting bolts to the standard face, and this -S version already carries the magnet for CMSE / DMSE switches. Order ACED20X30 as the direct successor and verify the ISO 21287 footprint first.
Replacement checklist
- ✓ Current-production ACE → ACED20X30S
- ✓ 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 ACPD20X30S FAQ
Because a rod exits both covers, force is equal in both directions: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, on the rod-side area of the 20 mm bore. At 1.0 MPa the maximum is 24.0 kgf. Operating pressure 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.
No, the ACPD family is discontinued. The current-production direct is ACED20X30 (swap the P for an E), which matches the same 20 mm bore, 30 mm stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard, and check the FA/FB flange or LB foot option you need.
