This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED80X400S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED80X400S 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 ACPD80X400S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD80X400S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø80mm bore and 400mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED80X400S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD80X400S
A double acting compact cylinder with a rod leaving both covers, the ACPD80X400S pushes and pulls with identical output: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa in either direction, because both strokes work on the rod-side area. The 400 mm stroke on this 80 mm bore is a made-to-order length beyond the 300 mm standard maximum, and the model is discontinued, with the ISO 21287 ACED80X400 as the current drop-in. The through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag.
The hard-anodized aluminium body with an S45C hard-chrome rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with fixed TPU bumpers at each end. This model carries the optional -S magnet, so CMSE or DMSE switches can be mounted for position feedback. Plan on roughly 1414 N of real work at 0.5 MPa, which lifts about 72 kg vertically with a 2:1 margin. 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 brackets bolt straight to the face. Confirm ISO 21287 mounting dimensions before swapping from the DIN-standard ACP footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED80X400S (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 ACPD80X400S Is Used
Reciprocating conveyor pushers
The through-rod drives a pusher plate from either cover with equal 2356.2 N force at 0.5 MPa, so pallets are indexed identically on the forward and return stroke over the 400 mm travel.
Gantry lift-and-lower stations
A rod at each end lets the upper rod carry a guide or sensor flag while the lower rod lifts about 72 kg vertically with a 2:1 margin, keeping the 80 mm bore symmetric inside a tight gantry frame.
Battery-change transfer carts
The 400 mm made-to-order stroke slides heavy battery trays between rack and cart, with the fixed TPU bumpers decelerating the 20 mm rod at both ends of the 30-500 mm/s travel.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD80X400S with the ACED80X400S
At 2356.2 N per side at 0.5 MPa, this 80 mm double-rod unit suits symmetric push-pull fixtures; step down to the 63 mm bore (1458.1 N) for lighter clamps or up to the 100 mm bore (3681.6 N) for heavier presses. The 400 mm stroke is non-standard and built to order. It does not hold position when air is lost, so add a rod lock or pilot check for a suspended load. If you need the single-rod version, the ACP (now ACE) or the adjustable ACPJ (now ACED / ACE) cover that job. Order FA/FB flange or LB foot mounting and PT ports; the -S magnet on this unit accepts CMSE / DMSE switches. For new projects, specify the ACED80X400 and confirm the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED80X400S
- ✓ 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 ACPD80X400S FAQ
Yes. As a double-rod cylinder, both strokes use the rod-side area, so force is equal either way: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa, with a maximum of 480.5 kgf at 1.0 MPa. 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 400 mm stroke is a non-standard made-to-order length (standard maximum for this bore is 300 mm).
Order the ACED80X400, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 80 mm bore, 400 mm stroke and force class, with the same short-body format that saves about 50% of the mounting length of an ISO 15552 profile cylinder. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before the swap. The -S magnet on this unit carries CMSE / DMSE switches; on the ACED the magnet is the optional -S code.
