This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X300 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X300 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 ACPD40X300
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X300 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 300mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X300 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X300
A double acting compact cylinder with a rod leaving both covers, the ACPD40X300 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 side load, gives a symmetric mount, and the rear rod can carry a sensor flag, while fixed TPU bumpers decelerate the piston at each end. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the hard-anodized aluminium body carries an S45C hard-chrome rod with a female M8x1.25 thread.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a long 300 mm travel still fits a tight gantry or guard. Plan on roughly 343 N of real work at 0.5 MPa, which lifts about 29 kg vertically with a 2:1 margin. Note that the 300 mm stroke exceeds the 200 mm standard maximum for this bore, so it is made to order. This model is discontinued: the current-production drop-in is ACED40X300, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X300 (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 ACPD40X300 Is Used
Reciprocating transfer gantry
The through-rod drives a carriage from either end with equal 571.8 N force at 0.5 MPa, and the rear rod carries a flag for position sensing on a 300 mm made-to-order stroke.
Push-pull fixture clamping
A plastics assembly jig uses the same rod-side force in both directions to clamp and release, with the fixed TPU bumpers softening each end of travel at 30-500 mm/s.
Vertical lift-and-lower station
A packaging line lowers about 29 kg trays vertically with a 2:1 margin, using the symmetric double-rod mount to resist rotation and side load through the full stroke.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X300 with the ACED40X300
Size around the 571.8 N per-direction output at 0.5 MPa. If your load needs less, an ACPD32X100 gives 345.6 N both ways; if you need more, step up to an ACPD50X with 881.2 N. Remember that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. Mount with FA/FB flange or LB foot brackets that bolt to the ISO 21287 face, and order the -S code if you want the optional magnet for CMSE / DMSE switches - without -S there is no magnet. Since ACPD40X300 is discontinued, order ACED40X300 as the current replacement in the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACED40X300
- ✓ 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 ACPD40X300 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 per direction, with a maximum of 116.6 kgf at 1.0 MPa. The 300 mm stroke exceeds the 200 mm standard maximum for the 40 mm bore, so it is made to order, and the model is discontinued - ACED40X300 is the current replacement.
It is a short-body compact cylinder with a hard-anodized aluminium body, S45C hard-chrome rod, female M8x1.25 rod thread, 1/8" ports and fixed TPU bumpers at both ends, saving about 50% of the mounting length of an ISO 15552 profile cylinder. Switches need the optional -S magnet code, which enables CMSE / DMSE reed or solid-state switches; without -S no magnet is fitted. Confirm ISO 21287 dimensions when moving to the ACED40X300 successor.
