This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X30S 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.

The AirTAC Airtac ACP Compact Cylinder ACP25X30S is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 30mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X30S (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP25X30S is a double acting DIN-standard compact cylinder with a 25 mm bore and 30 mm stroke, carrying the optional -S magnet so CMSE or DMSE reed and solid-state switches can be fitted for end-of-stroke sensing. At 0.5 MPa it pushes 245.4 N and pulls 206.2 N, rising to 343.6 N on the extend stroke at 0.7 MPa. Air supply runs 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at each end.
Its hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which makes it a strong fit for shallow fixtures and sliding guards. For sizing, treat roughly 147 N (about 15 kg of vertical lift) as the practical working force at 0.5 MPa instead of the full rating. Note that this model is discontinued: the current-production drop-in is ACE25X30, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X30S (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.
| 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 ACE25X30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| ACP | DIN compact cylinder (double-acting, discontinued). |
|---|---|
| 25 | Bore size in mm. |
| ×30 | Stroke length in mm. |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (adjustable stroke).
The 245.4 N push over a 30 mm stroke suits staking or marking small aluminium fittings on a compact bench fixture where a full-length cylinder will not fit.
Because the -S magnet is fitted, CMSE or DMSE switches confirm the slide has fully retracted before a packaging machine cycle continues.
About 15 kg of usable vertical force at 0.5 MPa holds PCB trays or connector blocks in a narrow CNC loading nest.
For a 30 mm stroke around 245 N of push, bore 25 sits well; if your load needs more, bore 32 delivers 402.1 N at 0.5 MPa, while bore 20 gives 157.1 N for lighter clamping. Keep in mind the piston drifts when air is removed, so add a rod lock or pilot check valve if the load must stay put. This unit already includes the -S magnet for CMSE / DMSE switches, and FA/FB flange, LB foot or CA/CB clevis mounts bolt to the same face. Order ACE25X30 as the current replacement.
Replacement checklist
At 0.5 MPa it pushes 245.4 N and pulls 206.2 N; at 0.7 MPa push is 343.6 N and pull 288.6 N. The theoretical maximum is 50.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi).
The ISO 21287-class body cuts mounting length by roughly half compared with an ISO 15552 profile cylinder, ideal for tight gantries. The S in the code means the optional magnet is fitted, so CMSE / DMSE switches mount directly. This model is discontinued; ACE25X30 is the current drop-in, so verify ISO 21287 dimensions first.
