This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X50S 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 ACP25X50S
The AirTAC Airtac ACP Compact Cylinder ACP25X50S is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 50mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X50S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP25X50S
A double acting compact cylinder in the DIN-standard ACP series, the ACP25X50S pairs a 25 mm bore with a 50 mm stroke and ships with the optional -S magnet already fitted, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing. At 0.5 MPa it pushes 245.4 N and pulls 206.2 N; at 0.7 MPa those figures rise to 343.6 N and 288.6 N. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarded gantries.
In practice, plan on about 147 N of usable push at 0.5 MPa rather than the full rating, and expect it to lift roughly 12 kg vertically once a 2:1 margin is applied - enough for small clamping plates or lightweight carriers. The hard-anodized aluminium body carries an S45C hard-chrome rod, a fixed TPU bumper sits at both ends, and speed runs 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). Note that this model is discontinued: the current-production drop-in is the ACE25X50, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X50S (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 ACE25X50S 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 ACP25X50S Is Used
Small-parts clamping fixture
The 245.4 N push at 0.5 MPa secures aluminium brackets or plastic housings in a CNC drilling jig, with the 50 mm stroke clearing the part for loading.
Packaging line pusher
Mounted beside a conveyor, the cylinder nudges cartons or blister trays into a lane at up to 500 mm/s, with CMSE switches on the -S magnet confirming each stroke.
Lab sample press
The compact short body fits inside a benchtop testing enclosure, applying about 147 N of working force to press sensor caps or seal sample vials.
Replacing the Airtac ACP Compact Cylinder ACP25X50S with the ACE25X50S
For this 50 mm stroke, the 25 mm bore delivers 245.4 N push at 0.5 MPa. Step down to a 20 mm bore (157.1 N) for lighter clamps, or up to a 32 mm bore (402.1 N) if the load grows. Remember the rod drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. Mounting options include FA/FB flange, LB foot and CA/CB clevis, and the female M6x1.0 rod thread accepts standard I/Y knuckles. Because the ACP line is discontinued, order the ACE25X50 as the current replacement and verify the ISO 21287 footprint against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACE25X50S
- ✓ 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 ACP25X50S 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 25 mm bore, 50 mm stroke double-acting cylinder with a 10 mm rod, M5x0.8 ports, female M6x1.0 rod thread, 0.15-1.0 MPa (22-145 psi) operating pressure, 1.5 MPa (215 psi) proof pressure, -20 to +70 C temperature range and 30-500 mm/s speed.
Order the ACE25X50, the current-production ISO 21287 successor: swap the P for an E and you get the same bore, stroke and force class in a matching short body. Before swapping, confirm the ISO 21287 mounting dimensions against your fixture, since the ACP was built to the older DIN-standard pattern. The ACE family also carries the FA/FB, LB and CA/CB mounting options and supports the optional magnet for CMSE / DMSE switches.
