This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X25SH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X25SH 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 ACP25X25SH
The AirTAC Airtac ACP Compact Cylinder ACP25X25SH is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X25SH (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP25X25SH
Double acting on both strokes, the ACP25X25SH is AirTAC's DIN-standard compact cylinder with a 25 mm bore and a short 25 mm stroke. At 0.5 MPa it pushes 245.4 N and pulls 206.2 N, rising to 343.6 N push at 0.7 MPa. 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, guards and slides where a full-length body will not fit. Because this unit carries the optional -S magnet code, CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing.
The hard-anodized aluminium body carries aluminium covers and an S45C hard-chrome rod, with a fixed TPU bumper at each end that only decelerates the piston - it never locks or holds a load, so use a rod lock or pilot check valve if the position must survive a loss of air. In practice, plan on roughly 147 N of usable push at 0.5 MPa, which lifts about 12 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production drop-in is the ACE25X25 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X25SH (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 ACE25X25SH 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 ACP25X25SH Is Used
Small-part clamping on CNC fixtures
The 245.4 N push at 0.5 MPa secures aluminium brackets or plastic housings in machining jigs, and the 25 mm stroke keeps the fixture footprint minimal.
Position-verified ejection on packaging lines
With the fitted -S magnet, CMSE or DMSE switches confirm the 25 mm push-off stroke is complete before the conveyor indexing step releases.
Compact press-fit of electronics pins
About 147 N of practical working force at 0.5 MPa presses connectors and pins into PCB assemblies inside tight bench-top fixtures.
Replacing the Airtac ACP Compact Cylinder ACP25X25SH with the ACE25X25SH
For a 25 mm stroke in this force class, the ACP25X25SH sits mid-range: a 20 mm bore gives 157.1 N push at 0.5 MPa for lighter clamping, while a 32 mm bore reaches 402.1 N when the load grows. If the piston must hold position with the valve centred, add a rod lock or pilot check valve - the fixed TPU bumpers do not brake. Mounting options include FA/FB flange, LB foot and CA/CB clevis, and the female M6x1.0 rod thread accepts standard I/Y knuckles. This model is discontinued; order the ACE25X25 as the current ISO 21287 replacement and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE25X25SH
- ✓ 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 ACP25X25SH 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 a double acting compact cylinder, 25 mm bore with a 10 mm rod, M5x0.8 port, PT body thread and female M6x1.0 rod thread. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a fixed TPU bumper at both ends.
AirTAC no longer produces the ACP family. The direct current-production successor is the ACE25X25, an ISO 21287 compact cylinder in the same bore, stroke and force class with a matching mounting family (FA/FB flange, LB foot, CA/CB clevis). Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping. The ACE also accepts the optional -S magnet for CMSE / DMSE switches.
