This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X5 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X5 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 ACPD40X5
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X5 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 5mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X5 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X5
A double acting compact cylinder with a rod leaving both covers, the ACPD40X5 delivers 571.8 N in each direction at 0.5 MPa and 800.5 N at 0.7 MPa, because both strokes work on the rod-side area. The 40 mm bore carries a 12 mm through-rod with a female M8x1.25 thread, a 1/8" PT port, and a fixed TPU bumper at each end. Its short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures a full-length body cannot reach.
The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag on a 5 mm stroke. At 0.5 MPa, plan for about 343 N of real work, which lifts roughly 29 kg vertically with a 2:1 margin. This model is discontinued; the current-production drop-in is the ACED40X5, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X5 (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 ACPD40X5 Is Used
Short-stamp ejection on PCB test rigs
The 5 mm stroke and 571.8 N of equal push-pull force eject a populated board from its test nest without disturbing adjacent fixtures.
Two-position gate indexing on packaging lines
A rod on each cover lets the rear rod trip a flag switch while the front rod nudges cartons 5 mm into the next lane at 30-500 mm/s.
Clamp retraction in CNC fixture plates
The through-rod resists side load in a milling fixture, and the compact body fits where an ISO 15552 profile cylinder is far too long.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X5 with the ACED40X5
For a 5 mm positioning job needing 571.8 N both ways, this 40 mm bore is the right class; step down to the 32 mm bore (345.6 N) for lighter clamps or up to the 50 mm bore (881.2 N) for heavier presses. Remember the piston drifts when air is lost, so add a rod lock or pilot check for a held load. Mounting brackets from the FA/FB flange and LB foot family bolt to the standard face, and CMSE / DMSE switches require the optional -S magnet code, which this model does not carry. Order the ACED40X5 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED40X5
- ✓ 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 ACPD40X5 FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, equal push and pull. At 1.0 MPa the maximum is 116.6 kgf. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, with a fixed TPU bumper at each end.
Order the ACED40X5, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 40 mm bore, 5 mm stroke and force class, but confirm the ISO 21287 mounting dimensions against your fixture before the swap, since the ACP was built to a DIN-standard body. If you need position switches, order the -S magnet code so CMSE / DMSE sensors can be used.
