This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X125B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X125B 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 ACP25X125B
The AirTAC Airtac ACP Compact Cylinder ACP25X125B is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 125mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X125B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP25X125B
Double acting on both strokes, the ACP25X125B is a DIN-standard compact cylinder with a 25 mm bore and 125 mm stroke. At 0.5 MPa it pushes 245.4 N and pulls 206.2 N, rising to 343.6 N and 288.6 N at 0.7 MPa, with a theoretical peak of 50.1 kgf at 1.0 MPa. The B code gives a male rod thread on the 10 mm rod, and the PT ports are M5x0.8. A fixed TPU bumper sits at both ends, and the hard-anodized aluminium body carries an S45C hard-chrome rod.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. As a planning rule, budget roughly 147 N (about 15 kg of push) for real work at 0.5 MPa instead of the full rating, which covers roughly 15 kg vertically with margin to spare. Note that this model is discontinued: the current-production successor is the ACE25X125 in the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X125B (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 ACE25X125B 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 ACP25X125B Is Used
Compact clamping fixture
The 245.4 N push at 0.5 MPa clamps small aluminium brackets in a machining jig, and the short body fits where a full-length profile cylinder cannot.
Push-off station on a packaging line
With 206.2 N of pull, the cylinder kicks light cartons off a conveyor at up to 500 mm/s, with the fixed TPU bumper softening each end of travel.
Lab sample press
About 15 kg of usable push at 0.5 MPa presses sample trays in a benchtop tester, and the 125 mm stroke clears the loading height.
Replacing the Airtac ACP Compact Cylinder ACP25X125B with the ACE25X125B
If 245.4 N of push at 0.5 MPa is more than your jig needs, the 20 mm bore (157.1 N) saves space; if you need more, step up to the 32 mm bore (402.1 N). The 125 mm stroke sits inside the 150 mm maximum standard stroke for this bore, so no made-to-order length is required. Choose FA/FB flange, LB foot or CA/CB clevis mounting to suit the fixture, and remember the male rod thread (B) pairs with I/Y knuckles. If you need position sensing, order the -S variant, which carries the optional magnet for CMSE / DMSE switches - this code has no magnet. For new builds, specify the ACE25X125 instead, as ACP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACE25X125B
- ✓ 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 ACP25X125B 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. The theoretical maximum is 50.1 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s. The model is discontinued; the ACE25X125 is the drop-in successor.
Only if you order the -S code, which adds the optional magnet for CMSE or DMSE reed and solid-state switches. This ACP25X125B has no magnet fitted, so no switch can be read on the body. Also note the cylinder does not hold position when air is lost - for a held load, add a rod lock or pilot check valve.
