This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X5H — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X5H 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.

About the Airtac ACP Compact Cylinder ACP25X5H
The ACP25X5H is a double acting DIN-standard compact cylinder with a 25 mm bore and a very short 5 mm stroke, built around a hard-anodized aluminium body with an S45C hard-chrome piston rod and a fixed TPU bumper at each end. At 0.5 MPa it pushes with 245.4 N and pulls with 206.2 N, rising to 343.6 N push at 0.7 MPa, with a theoretical peak of 50.1 kgf at 1.0 MPa. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarding where a full-length body cannot fit.
For sizing, treat about 147 N (roughly 15 kg of push) as the practical working force at 0.5 MPa instead of the full rating, and expect it to lift about 12 kg vertically once a 2:1 margin is applied. Note that this model carries no magnet, so CMSE or DMSE switches can only be used if you order the optional -S magnet version. The ACP family is discontinued; the current-production drop-in is the ACE25X5, which matches 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 ACE25X5H (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 ACE25X5H 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 ACP25X5H Is Used
Clamp actuation on small CNC fixtures
The 245.4 N push at 0.5 MPa (about 15 kg of usable clamp force) and 5 mm stroke suit quick clamping of small aluminium or plastic parts in a machining jig.
Short-throw part ejection
A 5 mm stroke is ideal for nudging a finished component off a nest or chute on an electronics assembly line, where the compact body fits inside tight guarding.
Press-fit verification in lab fixtures
With 343.6 N push at 0.7 MPa, the cylinder can seat light press-fit pins or connectors and lift about 12 kg vertically with a 2:1 margin.
Replacing the Airtac ACP Compact Cylinder ACP25X5H with the ACE25X5H
At 25 mm bore this sits mid-range: a 20 mm bore gives 157.1 N push at 0.5 MPa if you need less force, while a 32 mm bore delivers 402.1 N when the load grows. The 5 mm stroke is well inside the 150 mm maximum standard stroke for this bore, so it is a catalog item, not a made-to-order length. Remember the piston drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. Choose the -S code if you need CMSE / DMSE position switches, pick FA/FB flange, LB foot or CA/CB clevis mounting to suit the fixture, and specify the ACE25X5 as the current replacement since ACP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACE25X5H
- ✓ 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 ACP25X5H FAQ
It is a 25 mm bore, 5 mm stroke double acting compact cylinder: push 245.4 N and pull 206.2 N at 0.5 MPa, push 343.6 N and pull 288.6 N at 0.7 MPa, with a theoretical maximum of 50.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, air filtered to 40 um, port M5x1.0? No - the port is M5x0.8, rod thread M6x1.0 female, rod 10 mm.
Order the ACE25X5, the ISO 21287 successor made by swapping the P for an E. It matches the same 25 mm bore, 5 mm stroke and force class with a matching short body and mounting family (FA/FB flange, LB foot, CA/CB clevis). Because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. Also remember the magnet is only present on the optional -S code, which enables CMSE / DMSE switches.
