This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X400 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X400 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 ACPD100X400
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD100X400 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø100mm bore and 400mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED100X400 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD100X400
A double acting compact cylinder with a rod exiting both covers, the ACPD100X400 delivers an identical 3681.6 N in each direction at 0.5 MPa (5154.2 N at 0.7 MPa) because both strokes work on the rod-side area of the 100 mm bore. The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so a 400 mm stroke can sit inside a press frame or gantry where a full-length body would never fit. The through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag.
The 400 mm stroke is beyond the 300 mm standard limit for this bore, so it is a made-to-order build - plan lead time accordingly. A fixed TPU bumper sits at each end and only decelerates the piston; it never locks or holds a load, so for a suspended load add a rod lock or pilot check. Note that this model is discontinued: the current-production drop-in is the ACED100X400 in the ISO 21287 family, so confirm mounting dimensions before swapping. In practical terms, plan on about 2209 N of usable work at 0.5 MPa, which lifts roughly 187 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X400 (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 (Ø100mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 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 ACPD100X400 Is Used
Baler ram guide
The through-rod on both covers keeps the platen aligned in a scrap baler, with 3681.6 N of force in each direction at 0.5 MPa over the long 400 mm stroke.
Pallet pusher station
A packaging line pusher that must retract with the same force it extends uses the equal rod-side output, and the rear rod carries a position flag.
Die cart lift assist
With about 187 kg of vertical lift capacity at a 2:1 margin, the 100 mm bore raises die-cart fixtures inside a tight press-side gantry.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD100X400 with the ACED100X400
At 3681.6 N per side at 0.5 MPa, this 100 mm bore suits heavy clamping and lifting; step down to the 80 mm bore (2356.2 N) for lighter loads or accept that nothing smaller in the family comes close. The 400 mm stroke is non-standard for bore 100 (300 mm max standard), so order it as a made-to-order item. Female M16x1.5 rod thread and 1/4" PT ports are standard here; FA/FB flange or LB foot mounts bolt to the ISO 21287 face. The magnet is not fitted on this code - add the optional -S to run CMSE or DMSE switches. Since the ACPD is discontinued, spec the ACED100X400 as the current replacement and verify its ISO 21287 dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED100X400
- ✓ 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 ACPD100X400 FAQ
It is a double-rod cylinder, so output is equal both ways: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa, in either direction, on the rod-side area. Maximum force at 1.0 MPa is 750.8 kgf. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, with 1/4" ports and a female M16x1.5 rod thread.
No. Bore 100 tops out at 300 mm of standard stroke, so 400 mm is a made-to-order build. The ACPD family is discontinued; the current drop-in is the ACED100X400 (same bore, stroke and force class in the ISO 21287 series). Confirm the ISO 21287 mounting dimensions before swapping, since the ACP follows the DIN standard.
