This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X120B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X120B 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 ACP25X120B

About the Airtac ACP Compact Cylinder ACP25X120B
The ACP25X120B is a double acting DIN-standard compact cylinder with a 25 mm bore and 120 mm stroke, driving a 10 mm hard-chrome S45C rod through a male thread (the B code). At 0.5 MPa it pushes 245.4 N and pulls 206.2 N, rising to 343.6 N push at 0.7 MPa, with a theoretical ceiling of 50.1 kgf at 1.0 MPa. Air supply runs 0.15-1.0 MPa (22-145 psi) and rod speed 30-500 mm/s.
Its hard-anodized aluminium short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures a full-length body cannot reach. Plan on roughly 147 N (about 15 kg) of real work at 0.5 MPa, which lifts about 12 kg vertically with a 2:1 margin. FA/FB flange, LB foot and CA/CB clevis mounts bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches. Note this model is discontinued: the current drop-in is the ACE25X120, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X120B (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 ACE25X120B 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 ACP25X120B Is Used
Compact jig clamping
The 245.4 N push at 0.5 MPa clamps aluminium brackets in drilling fixtures where the short body must fit between guide posts, and the 120 mm stroke clears part loading.
Conveyor push-off station
Boxes up to about 12 kg can be nudged off a packaging line belt, with the 30-500 mm/s speed range tuned to match line tempo and the fixed TPU bumper softening end travel.
Small press ejection
Moulded clips are ejected from a bench-top die using the 343.6 N push at 0.7 MPa, with the male rod thread (B code) taking an I-type knuckle for the ejector plate.
Replacing the Airtac ACP Compact Cylinder ACP25X120B with the ACE25X120B
Size both ways: if 245.4 N push at 0.5 MPa is more than your jig needs, the 20 mm bore gives 157.1 N; if you need headroom, the 32 mm bore delivers 402.1 N at the same pressure. The 120 mm stroke sits inside the 150 mm standard range for bore 25, so no made-to-order length is required. Choose the B code for a male rod thread, add FA/FB, LB or CA/CB mounting to suit the fixture, and order the -S code only if CMSE / DMSE position sensing is needed. Remember a plain cylinder drifts when air is lost - add a rod lock or pilot check valve to hold a load. For new builds, specify the ACE25X120 instead, as this ACP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACE25X120B
- ✓ 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 ACP25X120B 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 50.1 kgf at 1.0 MPa. It is a double acting compact cylinder, 25 mm bore, 120 mm stroke, 10 mm rod with male thread, M5x0.8 port, operating 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, -20 to +70 C, with a fixed TPU bumper at both ends. The model is discontinued; the ACE25X120 is the current replacement.
Only if you order the -S code, which adds the optional magnet. With the magnet fitted, AirTAC CMSE reed or DMSE solid-state switches clamp onto the body for end-of-stroke signalling. A plain ACP25X120B has no magnet, so no switch will respond. Also confirm the ISO 21287 dimensions of the ACE25X120 successor before designing it into a new fixture.
