This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED80X40B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED80X40B 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 ACPD80X40B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD80X40B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø80mm bore and 40mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED80X40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD80X40B
A double acting compact cylinder with a rod leaving both covers, the ACPD80X40B pushes and pulls with the same 2356.2 N at 0.5 MPa (3298.7 N at 0.7 MPa), because both strokes work on the rod-side area of the 80 mm bore. The 20 mm through-rod resists rotation and side load, gives a symmetric mounting face, and lets the rear rod carry a sensor flag or a second tool. This model is discontinued; the current-production drop-in is the ISO 21287 ACED80X40, so confirm mounting dimensions before swapping.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight gantries and press fixtures. The hard-anodized aluminium body carries a fixed TPU bumper at each end, and the male rod thread (B code) bolts straight to I/Y knuckles on the FA/FB flange or LB foot. Plan on roughly 1414 N of usable push at 0.5 MPa, which is about 144 kg of practical vertical work, and remember the piston drifts if air is lost - add a rod lock or pilot check to hold a load.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED80X40B (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 ACPD80X40B Is Used
Twin-sided press fixture
The through-rod clamps a die from both covers in a stamping jig, delivering 2356.2 N each way at 0.5 MPa so one cylinder does the work of two single-rod units.
Conveyor gate diverter
A 40 mm stroke pushes product off a packaging line and retracts with equal 2356.2 N force, with the rear rod carrying a flag for a position check.
Pallet-stacker load pusher
About 144 kg of practical vertical or horizontal work at 0.5 MPa suits box-eject and pallet-position tasks on warehouse handling equipment.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD80X40B with the ACED80X40B
At 2356.2 N per side at 0.5 MPa, the 80 mm bore sits between the 63 mm (1458.1 N) and the 100 mm (3681.6 N), so drop to 63 mm if the load is under 900 N and up to 100 mm for heavy clamping. The 40 mm stroke is well inside the 300 mm standard limit for this bore. Choose the -S code if you later need CMSE or DMSE switches - this version has no magnet, so no sensor can be fitted. Since the ACPD is discontinued, order the ACED80X40 and verify the ISO 21287 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACED80X40B
- ✓ 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 ACPD80X40B FAQ
Both directions are identical because the double rod exposes the rod-side area on each stroke: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa, equal to about 240 kgf at the 1.0 MPa maximum. 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 1/4" port depends only on the 80 mm bore.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB flange or LB foot options. The ACPD80X40B is no longer in production; the current drop-in is the ACED80X40 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before you swap.
