This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED80X40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED80X40S 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 ACPD80X40S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD80X40S 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 ACED80X40S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD80X40S
A double acting compact cylinder with a rod leaving both covers, the ACPD80X40S pushes and pulls with identical force because each stroke works on the rod-side area: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa, either direction. The 80 mm bore drives a 20 mm through-rod over a 40 mm stroke at 30-500 mm/s, with a fixed TPU bumper at each end and 1/4" ports. The S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches mount directly on the body.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight gantries and machine guards. In practice, plan on about 1414 N of usable push at 0.5 MPa, and expect roughly 120 kg of vertical lift with a 2:1 margin. Note that this model is discontinued: the current-production successor is the ACED80X40, in the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED80X40S (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 ACPD80X40S Is Used
Reciprocating conveyor pushers
The 2356.2 N equal force in both directions returns heavy totes on a packaging line without a return spring, and the 40 mm stroke suits short transfer pitches.
Two-sided press fixtures
A rod on each cover lets one cylinder clamp a die or workpiece from both ends of a machining jig, with the fitted -S magnet feeding position signals to CMSE or DMSE switches.
Vertical lift-and-lower stations
With about 120 kg of practical vertical lift at a 2:1 margin, the through-rod guides a pallet elevator platen squarely; add a pilot check valve to hold position on air loss.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD80X40S with the ACED80X40S
At 2356.2 N per side at 0.5 MPa, this 80 mm bore sits between the 63 mm (1458.1 N) and 100 mm (3681.6 N) double-rod units, so drop to 63 if the load is light and step up to 100 for heavier clamping. The through-rod resists rotation and side load and gives a symmetric mount, and the back-end rod can carry a sensor flag. Remember that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. FA/FB flange and LB foot mountings bolt to the standard face. This model is discontinued; order the ACED80X40 as the drop-in and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED80X40S
- ✓ 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 ACPD80X40S FAQ
No, the two forces are identical because a rod exits both covers and both strokes use the rod-side area. At 0.5 MPa you get 2356.2 N in each direction, at 0.7 MPa you get 3298.7 N each way, and the maximum at 1.0 MPa is 480.5 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, on air filtered to 40 um.
It is a compact short-body design that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow guards and gantry frames. The ACPD family is no longer in production: the current drop-in is the ACED80X40, matching this 80 mm bore, 40 mm stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, and remember the fixed TPU bumpers only decelerate at the ends.
