This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED80X400SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED80X400SB 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.

The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD80X400SB 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 ACED80X400SB (ISO 21287 ACE), in the same bore, stroke and force class.
A double acting compact cylinder with a rod leaving both covers, the ACPD80X400SB 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 80 mm bore drives a 20 mm hard-chrome S45C rod through a hard-anodized aluminium body, running at 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling, and the B code gives a male rod thread.
The 400 mm stroke is longer than the 300 mm maximum standard stroke for bore 80, so it is a made-to-order build - confirm lead time when ordering. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters on a 400 mm stroke where every millimetre of envelope counts. The through-rod resists rotation and side load and lets the rear rod carry a sensor flag or a counter-faced tool. Fixed TPU bumpers sit at both ends. Note this model is discontinued; the current-production successor is ACED80X400, a drop-in in the same bore, stroke and force class - verify the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED80X400SB (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.
| 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).
| ACPD | DIN compact cylinder (double-rod, discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×400 | Stroke length in mm. |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (adjustable stroke).
The through-rod drives a pusher bar from both faces on a packaging line transfer, delivering 2356.2 N at 0.5 MPa in each direction so the return stroke indexes cartons with the same force as the advance.
With about 120 kg of vertical lift capacity at a 2:1 margin, the 80 mm bore ejects stamped housings from a lower die, while the rear rod carries a CMSE switch flag for stroke confirmation.
A male-threaded rod on both ends lets the machine builder bolt knuckles to either face, gripping and rotating aluminum extrusions in a welding cell where the short body fits a tight gantry envelope.
At 0.5 MPa this bore delivers 2356.2 N each way, which is about 1414 N of dependable working force if you plan on 60% of rating - roughly 144 kg of horizontal push. For vertical work the raw 2356.2 N equals about 240 kgf, so with a 2:1 margin it lifts about 120 kg vertically; step to bore 100 (3681.6 N at 0.5 MPa) if your part is heavier, or down to bore 63 (1458.1 N) if the load is lighter and space is tighter. The piston drifts when air is lost, so add a rod lock or pilot check valve for a held load. Mount via FA/FB flange or LB foot on the standard face, and remember the ACPD line is discontinued - ACED80X400 is the current replacement.
Replacement checklist
Yes - this is a double-rod cylinder, so force is equal both ways. At 0.5 MPa it delivers 2356.2 N, at 0.7 MPa it delivers 3298.7 N, and the theoretical maximum at 1.0 MPa is 480.5 kgf. Both strokes use the rod-side area because a 20 mm rod exits each cover. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed spans 30-500 mm/s.
Yes. Bore 80 has a 300 mm maximum standard stroke, so 400 mm is a non-standard, made-to-order build - expect a factory lead time rather than shelf stock. Also note the ACPD family is discontinued: the current-production drop-in is ACED80X400, the same bore, stroke and force class in the ISO 21287 series. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP follows the older DIN-standard face.
