This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X55 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X55 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 ACPD100X55
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD100X55 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 ACED100X55 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD100X55
A double acting compact cylinder with a rod exiting both covers, the ACPD100X55 delivers 3681.6 N at 0.5 MPa in each direction because both strokes work on the rod-side area. The 100 mm bore pushes 5154.2 N at 0.7 MPa either way, so there is no push-versus-pull difference to design around. Its short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits tight press fixtures and gantry clamps where a full-length body will not.
The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag on automated stations. A fixed TPU bumper sits at both ends, and the hard-anodized aluminium body carries an S45C hard-chrome rod with a female M16x1.5 thread. At 0.5 MPa the 3681.6 N rating converts to roughly 375 kg of force, so plan on about 187 kg of vertical lift with a 2:1 margin. Note this model is discontinued: the current-production drop-in is the ACED100X55, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X55 (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 ACPD100X55 Is Used
Bottle capping press
The 3681.6 N both-ways force at 0.5 MPa drives a capping head on a beverage line, and the short body slots under a low conveyor guard where a full-length cylinder cannot reach.
Dual-sided weld fixture clamp
A rod on each cover lets one cylinder clamp from both sides of an automotive bracket jig, with the rear rod carrying a sensor flag for PLC confirmation.
Pallet stamping station
The 55 mm stroke stamps batch codes on pallet feet, and the through-rod's resistance to side load keeps the stamp square over repeated cycles at 30-500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD100X55 with the ACED100X55
Size between bores: the 80 mm double-rod version gives 2356.2 N at 0.5 MPa, while stepping up is not possible within this family since 100 mm is the largest bore. With 3681.6 N available both ways, a 2:1 margin still leaves about 187 kg of usable vertical lift. This plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay put. Mounting brackets bolt to the ISO 21287 face, and the optional -S magnet (ordered in the code) enables CMSE / DMSE switches; without -S there is no magnet. Order the ACED100X55 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED100X55
- ✓ 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 ACPD100X55 FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa, equal in extend and retract. At 1.0 MPa the maximum output is 750.8 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and a fixed TPU bumper at each end.
Order the ACED100X55, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 100 mm bore, 55 mm stroke and force class, and accepts the same FA/FB flange, LB foot and clevis bracket family. Since the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before the swap. The optional -S magnet code carries over if you need CMSE / DMSE switches.
