This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X70 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X70 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 ACPD40X70
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X70 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 70mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X70 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X70
A double acting compact cylinder with a rod leaving both covers, the ACPD40X70 pushes and pulls with identical output: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa in each direction, because both strokes work on the rod-side area of the 40 mm bore. The through-rod resists rotation and light side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end and stroke speed runs 30-500 mm/s.
The short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. In practice, plan on about 343 N of usable work at 0.5 MPa, which lifts roughly 29 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production drop-in is ACED40X70, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X70 (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 (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 572 N |
| 0.7 MPa | 800 N |
| Max (@1.0 MPa) | 117 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 ACPD40X70 Is Used
Reciprocating transfer carriage
The through-rod drives a slide table on a packaging line, pushing and pulling with the same 571.8 N at 0.5 MPa so the return stroke carries the same load.
Clamp-and-eject station
Front rod clamps a machined housing while the rear rod kicks the finished part off the fixture, using one 40 mm bore for two working ends.
Flag-driven position check
With the optional -S magnet ordered, a CMSE or DMSE switch tracks the rear rod as a moving flag on an assembly gantry with 70 mm of travel.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X70 with the ACED40X70
At 70 mm stroke this sits well inside the 200 mm maximum standard stroke for the 40 mm bore, so it is a catalog item, not a made-to-order build. If 571.8 N at 0.5 MPa is more than the job needs, the 32 mm bore gives 345.6 N; if you need more, the 50 mm bore delivers 881.2 N. A plain double-rod cylinder will not hold position when air is lost, so add a rod lock or pilot check for a suspended load. This unit has the female M8x1.25 rod thread and PT ports with no magnet fitted; order the -S code if you want CMSE / DMSE switch capability. For new projects, specify ACED40X70 instead.
Replacement checklist
- ✓ Current-production ACE → ACED40X70
- ✓ 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 ACPD40X70 FAQ
Output is equal both ways because a rod exits each cover and both strokes use the rod-side area: 571.8 N at 0.5 MPa, 800.5 N at 0.7 MPa, and up to 116.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and speed runs 30-500 mm/s.
The ACPD family is out of production. The current drop-in is ACED40X70, the ISO 21287 successor with the same bore, stroke and force class. Since the ACP is DIN-standard, verify the ISO 21287 mounting dimensions against your fixture before swapping, and remember the magnet is only present when the -S code is ordered.
