This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X40S 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 ACPD100X40S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD100X40S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø100mm bore and 40mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED100X40S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD100X40S
Double acting with a rod leaving both covers, the ACPD100X40S pushes with identical force in each direction: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa, because both strokes work on the rod-side area of the 100 mm piston. The through-rod resists rotation and side load, gives a symmetric mount, and lets the rear rod carry a sensor flag, while fixed TPU bumpers decelerate the piston at each end. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be fitted for position feedback.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight press fixtures and gantry clamps. In practice, plan on about 2209 N of usable push at 0.5 MPa, and for vertical work the rod can lift about 187 kg with a 2:1 margin. Note that this model is discontinued: the current-production drop-in is the ACED100X40, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X40S (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 ACPD100X40S Is Used
Baler ram positioning
The symmetric through-rod and 3681.6 N force in both directions suit a recycling baler ram that must be driven back and forth between CMSE switch positions over a 40 mm indexing stroke.
Pallet clamp fixture
In a warehouse palletizer, the double rod clamps and releases pallet collars with equal 5154.2 N force at 0.7 MPa, and the rear rod carries a flag for DMSE end-position sensing.
Die cart lift assist
A stamping shop die cart uses the 100 mm bore to raise about 187 kg vertically with a 2:1 margin, with LB foot mounting keeping the short body inside the cart frame.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD100X40S with the ACED100X40S
At 3681.6 N per direction, bore 100 sits at the top of the ACPD range; if your load needs less, bore 80 delivers 2356.2 N at 0.5 MPa, and there is no larger bore in the family. The 40 mm stroke is well inside the 300 mm maximum standard stroke for bore 100, so it is a catalogue item. Remember that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay put. FA/FB flange and LB foot mounts bolt to the ISO 21287 face, and the -S magnet in this model accepts CMSE / DMSE switches. For new projects, order the ACED100X40 instead.
Replacement checklist
- ✓ Current-production ACE → ACED100X40S
- ✓ 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 ACPD100X40S FAQ
Because a rod exits both covers, output is equal in both directions: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa, on the rod-side area of the 100 mm piston. At the full 1.0 MPa rating the theoretical maximum is 750.8 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed range is 30-500 mm/s.
The hard-anodized aluminium body follows the ISO 21287 short format, cutting about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end that decelerates the piston at stroke ends only. This ACPD100X40S is discontinued; the current-production replacement is the ACED100X40 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.
