This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X70B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X70B 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 ACPD40X70B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X70B 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 ACED40X70B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X70B
A double acting compact cylinder with a rod leaving both covers, the ACPD40X70B delivers 571.8 N in each direction at 0.5 MPa (800.5 N at 0.7 MPa) because both strokes work on the rod-side area of the 40 mm bore. The male rod thread (B code) bolts straight to I/Y knuckles, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. Its short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and gantries.
In practice, plan on roughly 343 N of real work at 0.5 MPa, which lifts about 29 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a fixed TPU bumper at each end, and speed spans 30-500 mm/s. Note that this model is discontinued: the current-production drop-in is the ACED40X70, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X70B (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 ACPD40X70B Is Used
Symmetric press fixture
The equal 571.8 N output in both directions suits a punch-and-return station on an electronics assembly press, where the through-rod keeps the tooling plate square under side load.
Reciprocating pusher arm
A packaging line diverter that pushes cartons then retracts under the same 571.8 N force uses the rear rod as a position flag mount for a proximity sensor bracket.
Gantry lift column
With about 29 kg of vertical lift capacity at a 2:1 margin, the 70 mm stroke raises small fixture plates inside a machine guard where a full-length profile cylinder would not fit.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X70B with the ACED40X70B
For a 70 mm stroke with equal force both ways, the 40 mm bore gives 571.8 N at 0.5 MPa; step down to ACPD32 (345.6 N) for lighter clamping or up to ACPD50 (881.2 N) for heavier presses. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for held loads. This unit has no magnet, so CMSE / DMSE switches require the -S code; FA/FB flange and LB foot mountings fit the ISO 21287 face. Order the ACED40X70 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED40X70B
- ✓ 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 ACPD40X70B FAQ
Because a rod exits both covers, force is equal both ways: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, with a maximum of 116.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 1/8" port serves both chambers. The 12 mm rod ends in a male thread (B code).
No, the ACPD40X70B is discontinued. The current-production drop-in is the ACED40X70, the ISO 21287 successor in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint. FA/FB flange and LB foot brackets bolt to the same face family.
