This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED80X40SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED80X40SB 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 ACPD80X40SB
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD80X40SB 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 ACED80X40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD80X40SB
A double acting compact cylinder with a rod leaving both covers, the ACPD80X40SB delivers 2356.2 N in either direction at 0.5 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 plane, and lets the rear rod carry a sensor flag, while fixed TPU bumpers take the end-of-travel shock. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches mount directly on the body.
The hard-anodized aluminium body follows the ISO 21287 short format, cutting roughly 50% of the mounting length compared with an ISO 15552 profile cylinder, which matters inside tight guards and gantries. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it moves at 30-500 mm/s across -20 to +70 C. Note that the ACPD range is discontinued: the current-production drop-in is the ACED80X40 in the same bore, stroke and force class, so confirm ISO 21287 mounting dimensions before swapping. As a sizing guide, plan on about 1414 N (roughly 144 kg) of usable push at 0.5 MPa, enough to lift about 120 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED80X40SB (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 ACPD80X40SB Is Used
Twin-sided press fixture
The 40 mm stroke and 2356.2 N per side at 0.5 MPa let one through-rod clamp or eject on both faces of an aluminium die-cast housing in a machining cell.
Bidirectional gate diverter
Equal force both ways suits a conveyor pusher that sorts cartons left or right on a packaging line, with the rear rod driving a flag past a CMSE switch for position feedback.
Gantry lift-and-lower stage
With about 120 kg of vertical lift capability at a 2:1 margin, the symmetric double-rod mount raises and lowers a small pallet nest inside a compact gantry frame.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD80X40SB with the ACED80X40SB
Pick this 80 mm bore when your fixture needs about 2356.2 N per direction at 0.5 MPa or 3298.7 N at 0.7 MPa over a short 40 mm travel. If the load is lighter, the 63 mm bore gives 1458.1 N at 0.5 MPa; if you need more, the 100 mm bore reaches 3681.6 N. Remember the piston drifts when air is lost, so add a rod lock or pilot check valve for a held load. The male rod thread (B code) and PT ports suit external rod hardware, and the -S magnet on this unit pairs with CMSE / DMSE switches. Since ACPD is discontinued, order the ACED80X40 as the current ISO 21287 equivalent and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED80X40SB
- ✓ 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 ACPD80X40SB FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area of the 80 mm bore: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa, equal in extend and retract. At the full 1.0 MPa rating the peak force is 480.5 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the 20 mm rod carries a male thread with 1/4" ports.
The ACPD family is no longer in production; the current drop-in is the ACED80X40, which swaps the P for an E and matches the same 80 mm bore, 40 mm stroke and force class. Confirm the ISO 21287 mounting dimensions before the swap since the ACP is DIN-standard. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange or LB foot mounts bolt straight on. This unit carries the optional -S magnet for CMSE / DMSE switches, and fixed TPU bumpers decelerate the piston at each end.
