This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X50 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 ACP25X50
The AirTAC Airtac ACP Compact Cylinder ACP25X50 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 ACE25X50 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP25X50
A double acting compact cylinder in the DIN-standard ACP series, the ACP25X50 pairs a 25 mm bore with a 50 mm stroke in a hard-anodized aluminium body with an S45C hard-chrome rod. 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. The 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.
In practice, plan on about 147 N (roughly 15 kg of thrust) for real work at 0.5 MPa, which means this cylinder can lift about 7 kg vertically with a 2:1 margin. Air supply is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and fixed TPU bumpers at both ends. Note the ACP family 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 ACE25X50 (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 ACE25X50 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 ACP25X50 Is Used
Small-part clamping fixture
A 25 mm bore delivering 245.4 N at 0.5 MPa clamps aluminium brackets or plastic housings in a CNC second-op jig, with the 50 mm stroke clearing part loading by hand.
Packaging line pusher
On a carton divert station, the compact body mounts between conveyor rails and pushes lightweight boxes off the line at speeds up to 500 mm/s.
Lab sample press
A benchtop sample-holding press uses the 50 mm stroke and about 15 kg of usable thrust to seat vials or test coupons without damaging them.
Replacing the Airtac ACP Compact Cylinder ACP25X50 with the ACE25X50
For a 50 mm stroke at this force level, compare the 20 mm bore (157.1 N push at 0.5 MPa) if the load is lighter, or step up to the 32 mm bore (402.1 N push) for heavier clamping. The 25 mm bore tops out at a 150 mm standard stroke, so 50 mm sits comfortably inside it. Mounting choices are FA/FB flange, LB foot and CA/CB clevis, and rod-end knuckles bolt to the standard face. Position sensing needs the optional -S magnet code; without it no CMSE or DMSE switch can be fitted. Remember the piston drifts when air is lost, so add a rod lock or pilot check valve for held loads. Order the ACE25X50 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE25X50
- ✓ 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 ACP25X50 FAQ
At 0.5 MPa it pushes 245.4 N and pulls 206.2 N; at 0.7 MPa those rise to 343.6 N push and 288.6 N pull. The theoretical maximum is 50.1 kgf at 1.0 MPa. It is a double acting cylinder with a 25 mm bore, 50 mm stroke, 10 mm rod, M6x1.0 female rod thread and M5x0.8 ports, running on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um.
Sensors are only possible when the optional -S magnet is ordered; the base ACP25X50 has no magnet, so CMSE or DMSE switches cannot be mounted on it. The ACP series itself is discontinued - the current-production successor is the ACE25X50, a drop-in in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions against your fixture before swapping.
