This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X80, 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 ACPD20X80
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X80 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 80mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X80 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X80
A double acting compact cylinder with a rod leaving both covers, the ACPD20X80 delivers 117.8 N in each direction at 0.5 MPa (164.9 N at 0.7 MPa), because both strokes work on the rod-side area. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag on a pick-and-place arm. Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding.
This 20 mm bore unit is now discontinued; the current-production direct is the ACED20X80 (swap the P for an E), so confirm ISO 21287 mounting dimensions before ordering. A fixed TPU bumper sits at each end, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the optional -S magnet enables CMSE / DMSE switches (no magnet without the -S code).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X80 (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 ACPD20X80 Is Used
Symmetric part ejection
The through-rod pushes a machined aluminum bracket off a fixture with equal 117.8 N force on either stroke, keeping the part centered without a guide rail.
Flag-driven stroke sensing
With the optional -S magnet ordered, a CMSE or DMSE switch rides the front rod on a 80 mm stroke indexing slide, giving end-of-travel signals at 30-500 mm/s.
Twin-sided press station
Both rods of the double-rod body act on a small electronics assembly jig, applying about 70 N of usable force per side at 0.5 MPa for snap-fit pressing.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X80 with the ACED20X80
At 117.8 N per side at 0.5 MPa, this 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 push. The 80 mm stroke sits within the 100 mm standard limit for bore 20. It does not hold position when air is lost - add a rod lock or pilot check for a held load. Choose the female M6x1.0 rod thread as coded, or the B variant for male thread, and order the -S magnet if CMSE / DMSE sensing is planned. For new builds, specify the ACED20X80 instead.
Replacement checklist
- ✓ Current-production ACE → ACED20X80
- ✓ 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 ACPD20X80 FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal either way: 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), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8. The rod is 10 mm with an M6x1.0 female thread.
Order the ACED20X80, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 20 mm bore, 80 mm stroke and force class, and accepts the FA/FB flange, LB foot and CA/CB clevis mounting family. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. Also note the magnet is only fitted when the -S code is ordered.
