This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X5 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X5 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 ACP Compact Cylinder ACP25X5
The AirTAC Airtac ACP Compact Cylinder ACP25X5 is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X5 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP25X5
The ACP25X5 is a double acting DIN-standard compact cylinder with a 25 mm bore and a very short 5 mm stroke, driving a 10 mm rod through a female M6x1.0 rod thread and fed by an M5x0.8 port. At 0.5 MPa it pushes 245.4 N and pulls 206.2 N, rising to 343.6 N push and 288.6 N pull at 0.7 MPa. Its hard-anodized aluminium body with an S45C hard-chrome rod runs on 0.15-1.0 MPa (22-145 psi) air at 30-500 mm/s, with a fixed TPU bumper at each end.
Because the short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this unit slots into tight clamping fixtures where a full-length cylinder cannot. For sizing, plan on roughly 147 N (about 15 kg) of real work at 0.5 MPa, or expect it to lift about 12 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production drop-in is the ACE25X5, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X5 (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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
The ACE25X5 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP25X5 Is Used
Micro clamping on CNC fixtures
The 5 mm stroke is ideal for a short clamp kick on a milling vise or jig button, where 245.4 N at 0.5 MPa holds a small aluminium part firmly without over-squeezing.
Eject pin on packaging tooling
A 5 mm push is enough to kick a finished blister or tray off a forming station on a small packaging line, and the compact body fits inside the guard.
Index stop on an assembly dial
Use the short stroke to raise and lower a stop pin that indexes parts on a rotary assembly table, cycling at 30-500 mm/s between stations.
Replacing the Airtac ACP Compact Cylinder ACP25X5 with the ACE25X5
At 245.4 N push (0.5 MPa), the 25 mm bore sits between the 20 mm bore (157.1 N) and the 32 mm bore (402.1 N); pick 20 mm for lighter clamps or 32 mm when you need roughly 1.6x the force. The 5 mm stroke is well inside the 150 mm standard range for this bore. This unit has no magnet, so position switches cannot be fitted - order the -S code (ACP25X5S) if you need CMSE or DMSE sensors. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the same face. Since ACP is discontinued, specify the ACE25X5 as the current replacement and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE25X5
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACP Compact Cylinder ACP25X5 FAQ
At 0.5 MPa it pushes 245.4 N and pulls 206.2 N; at 0.7 MPa, 343.6 N push and 288.6 N pull; theoretical maximum is 50.1 kgf at 1.0 MPa. It is double acting with a 25 mm bore, 5 mm stroke, 10 mm rod, M5x0.8 port, female M6x1.0 rod thread, 0.15-1.0 MPa (22-145 psi) operating range, -20 to +70 C, and 30-500 mm/s speed.
Order the ACE25X5, the current ISO 21287 production model that swaps the P for an E and matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before the swap, since the ACP was built to a DIN standard. The ACE also accepts FA/FB flange, LB foot and CA/CB clevis mountings, and the optional -S magnet enables CMSE or DMSE switches.
