This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X75S 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 ACP25X75S
The AirTAC Airtac ACP Compact Cylinder ACP25X75S is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 75mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X75S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP25X75S
A double acting compact cylinder in the DIN-standard ACP series, the ACP25X75S runs a 25 mm bore with a 75 mm stroke and delivers 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit. The -S code on this model means the optional magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the hard-anodized aluminium body.
At 0.7 MPa the same bore reaches 343.6 N push and 288.6 N pull, with a theoretical ceiling of 50.1 kgf at 1.0 MPa. As a working rule, plan on about 147 N of usable force at 0.5 MPa, which lifts roughly 15 kg vertically with a 2:1 margin - enough to match a real part weight before you order. A fixed TPU bumper at each end decelerates the piston, and the S45C hard-chrome rod on a 10 mm diameter carries side loads typical of pick-and-place duty. Note this model is discontinued: the current-production drop-in is the ACE25X75, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X75S (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 ACE25X75S 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 ACP25X75S Is Used
Compact jig clamping
The 245.4 N push at 0.5 MPa clamps small aluminium brackets in drilling fixtures, and the short body fits inside jig plates where an ISO 15552 profile cylinder would overhang.
Sensed part ejection
With the fitted -S magnet, CMSE or DMSE switches confirm rod position on a 75 mm eject stroke, pushing rejected parts off a conveyor check station at up to 500 mm/s.
Light vertical lift in gantries
The bore lifts about 15 kg vertically with a 2:1 margin, suiting small pick-and-place gantries that lower sensor heads into test sockets within tight Z-axis envelopes.
Replacing the Airtac ACP Compact Cylinder ACP25X75S with the ACE25X75S
Size both ways before committing: one bore down, the ACP20 series gives 157.1 N push at 0.5 MPa, while one bore up, the ACP32 reaches 402.1 N - the 25 mm bore sits between them at 245.4 N push and 206.2 N pull. If the load must stay put when air is lost, add a rod lock or pilot check valve, because a plain cylinder of this type drifts when the valve centres. Mounting options include FA/FB flange, LB foot and CA/CB clevis brackets that bolt to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke sensing. The 75 mm stroke sits well inside the 150 mm maximum standard stroke for this bore, so it is a catalogue item - but the model itself is discontinued, and the ACE25X75 is the current replacement in the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACE25X75S
- ✓ 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 ACP25X75S FAQ
At 0.5 MPa it pushes 245.4 N and pulls 206.2 N; at 0.7 MPa it pushes 343.6 N and pulls 288.6 N, with a theoretical maximum of 50.1 kgf at 1.0 MPa. It is a double acting compact cylinder with a 25 mm bore, 75 mm stroke, 10 mm rod with female M6x1.0 thread, M5x0.8 ports, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s and a fixed TPU bumper at both ends.
Order the ACE25X75, the ISO 21287 successor made by swapping the P for an E. It matches the same 25 mm bore, 75 mm stroke and force class with a similar short body and mounting family, but because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. The ACE family also covers related types such as ASP/ATP single-acting, ACPD double-rod and ACPJ adjustable-stroke models.
