This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X55S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X55S 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 ACPD100X55S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD100X55S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø100mm bore and 55mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED100X55S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD100X55S
A double acting compact cylinder with a rod through BOTH covers, the ACPD100X55S delivers 3681.6 N in each direction at 0.5 MPa because both strokes work on the rod-side area. The 100 mm bore carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped on for end-of-stroke sensing. Its hard-anodized aluminium body is an ISO 21287 short build, cutting about 50% of the mounting length of an ISO 15552 profile cylinder, which suits tight press fixtures and gantry frames.
The through-rod resists rotation and side load and gives a symmetric mount, while the rear rod can carry a sensor flag or a second tooling plate. Fixed TPU bumpers sit at both ends, the S45C hard-chrome rod is 25 mm, and speed spans 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). For planning, treat roughly 2209 N (about 225 kgf) as the usable push at 0.5 MPa, or expect it to lift about 187 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production drop-in is ACED100X55, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X55S (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 ACPD100X55S Is Used
Press fixture clamping
The 3681.6 N equal force both ways clamps and releases heavy die-locating blocks on a stamping press table with the same rated push either direction.
Battery-change lift table
A 55 mm stroke raising a scissor link that lifts about 187 kg vertically at a 2:1 margin, with the through-rod keeping the linkage square under side load.
Gantry part presence station
CMSE or DMSE switches on the -S magnet confirm clamp and unclamp positions on an automotive pallet loop, with the rear rod driving a flag plate.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD100X55S with the ACED100X55S
At 3681.6 N per side (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 the 100 mm class has no larger standard bore in this family. The 55 mm stroke sits well inside the 300 mm maximum standard stroke for bore 100. Remember the piston drifts when air is lost, so add a rod lock or pilot check for a held load. Mounting brackets and I/Y knuckles bolt to the ISO 21287 face, and the -S magnet is already fitted on this code. Replacement: ACED100X55.
Replacement checklist
- ✓ Current-production ACE → ACED100X55S
- ✓ 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 ACPD100X55S FAQ
Because a rod exits both covers, force 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. The maximum force at 1.0 MPa is 750.8 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
No - the ACPD family is discontinued. The current-production drop-in is ACED100X55 (swap the P for an E), which matches the same 100 mm bore, 55 mm stroke and force class in the ISO 21287 short-body format. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to a DIN-standard footprint.
