This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED80X20B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED80X20B in place of this model. 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 ACPD80X20B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD80X20B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø80mm bore and 20mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED80X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD80X20B
A double acting compact cylinder with a rod leaving both covers, the ACPD80X20B pushes and pulls with identical force: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa in either direction, since both strokes work on the rod-side area of the 80 mm bore. The through-rod resists rotation and side load, gives a symmetric mounting point at each end, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at both ends and stroke speed runs 30-500 mm/s.
The hard-anodized aluminium body follows the short ISO 21287 format, cutting roughly 50% of the mounting length compared with an ISO 15552 profile cylinder, so it slots into tight clamping stations and gantries. The male rod thread (B code) bolts straight to I/Y knuckles on the ISO 21287 face. For planning, treat about 1414 N (roughly 144 kg of thrust) as the usable working force at 0.5 MPa. Note this model is discontinued: the current-production drop-in is the ACED80X20, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED80X20B (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 (Ø80mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 2356 N |
| 0.7 MPa | 3299 N |
| Max (@1.0 MPa) | 481 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 ACPD80X20B Is Used
Symmetric press-fit station
The 2356.2 N output in both directions suits a press head that must return with the same force it presses with, on a short 20 mm stroke inside a compact fixture.
Reciprocating transfer slider
A through-rod on both covers lets a pallet shuttle ride either rod end, with the rear rod doubling as a mount for a position flag.
Pallet gate actuator
With about 240 kg of thrust equivalent at 0.5 MPa, the 80 mm bore swings heavy warehouse gate arms through a 20 mm throw at up to 500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD80X20B with the ACED80X20B
At 80 mm bore this is the second-strongest ACPD size: 2356.2 N per direction at 0.5 MPa, above the 63 bore (1458.1 N) and below the 100 bore (3681.6 N). Choose it when a 20 mm stroke must deliver equal force forward and backward, for example a symmetric clamp or a reciprocating transfer. It will not hold a load if air is lost, so add a rod lock or pilot check for held positions. This unit has no magnet; order the -S code if CMSE / DMSE switches are needed. Since ACPD is discontinued, spec the ACED80X20 as the current replacement and verify the ISO 21287 hole pattern.
Replacement checklist
- ✓ Current-production ACE → ACED80X20B
- ✓ 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 ACPD80X20B FAQ
Because it is a double-rod cylinder, output is equal both ways: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa per direction, with a maximum of 480.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 1/4" port depends only on the 80 mm bore. In practice, plan on roughly 144 kg of usable thrust at 0.5 MPa rather than the full rating.
AirTAC no longer produces the ACPD family. The current-production replacement is the ACED80X20 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class with FA/FB flange, LB foot and clevis mounting options. Before swapping, confirm the ISO 21287 mounting dimensions against your existing DIN-standard ACP footprint. Also remember the magnet is only fitted when the -S code is ordered.
