This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X80B, 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 ACPD20X80B
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X80B 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 ACED20X80B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X80B
A double acting compact cylinder with a rod leaving both covers, the AirTAC ACPD20X80B delivers 117.8 N in either direction at 0.5 MPa because both strokes work on the rod-side area. The 20 mm bore carries a 10 mm through-rod with a male thread (the B code) on each end, and the 80 mm stroke sits inside the 100 mm maximum standard stroke for this bore. Air supply is 0.15-1.0 MPa (22-145 psi), speed runs 30-500 mm/s, and the port is M5x0.8.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. A fixed TPU bumper sits at each end, and the rear rod can carry a sensor flag or a second tooling plate. Note this model is discontinued: the current-production direct is the ACED20X80, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X80B (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 ACPD20X80B Is Used
Bidirectional parts pusher
The equal 117.8 N output both ways lets one ACPD20X80B eject a machined aluminum housing off a fixture and retract a stop pin, with no direction-dependent force loss.
Sensor-flag carriage on a pick station
The rear rod carries a flag past a switch on a small electronics assembly gantry; order the -S code to enable CMSE or DMSE switches, since no magnet is fitted otherwise.
Symmetric label press
A packaging line uses the through-rod to mount a light embossing head on the front rod and a guide bushing on the rear rod, keeping the 80 mm stroke balanced over about 6 kg of vertical load.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X80B with the ACED20X80B
At 117.8 N per side at 0.5 MPa, this 20 mm bore suits light clamping and transfer work; step down to the 16 mm bore (75.4 N) for smaller fixtures or up to the 25 mm bore (206.2 N) when you need more push. The 80 mm stroke is standard for this bore, so no made-to-order build is required. The through-rod resists rotation and side load better than a single-rod design, and the male rod thread (B code) takes I/Y knuckles directly. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. This unit is discontinued - order the ACED20X80 as the current ISO 21287 replacement and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED20X80B
- ✓ 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 ACPD20X80B FAQ
Because a rod exits both covers, output is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, using the rod-side area. Maximum force at 1.0 MPa is 24.0 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the port is M5x0.8.
The hard-anodized aluminium body follows the short ISO 21287-class format, cutting about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange or LB foot options. A fixed TPU bumper at each end decelerates the piston; it is not adjustable and never holds a load. This model is discontinued - the ACED20X80 is the current direct, so confirm ISO 21287 mounting dimensions before ordering.
