This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X70 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X70 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 ACP25X70 is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X70 (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP25X70 is a double acting DIN-standard compact cylinder with a 25 mm bore and 70 mm stroke, built around a hard-anodized aluminium body with covers threaded on and an S45C hard-chrome piston rod. At 0.5 MPa it pushes 245.4 N and pulls 206.2 N, rising to 343.6 N push and 288.6 N pull at 0.7 MPa, with a theoretical maximum of 50.1 kgf at 1.0 MPa. Air is the only fluid, filtered to 40 um, over 0.15-1.0 MPa (22-145 psi).
Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits tight jigs and guarding where a full-length body cannot. For sizing, treat about 147 N (0.6 of the push figure) as the usable working force, and note it lifts roughly 25 kg vertically at 0.5 MPa - halve that for a 2:1 margin. A fixed TPU bumper sits at both ends, speed runs 30-500 mm/s, and the optional -S magnet enables CMSE / DMSE switches. This model is discontinued; the current-production drop-in is ACE25X70.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X70 (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 ACE25X70 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. |
| ×70 | 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 at 0.5 MPa clinches snap-fit plastic housings or crimps small terminals on an assembly bench, with the 70 mm stroke clearing part loading by hand.
Mounted on a packaging line guard, the short body tucks top flaps of small cartons at up to 500 mm/s, using the fixed TPU bumper to soften each end of travel.
Ordered with the -S magnet code, CMSE or DMSE switches confirm a workpiece is seated in a CNC gantry nest, retracting the probe between cycles.
At 25 mm bore this sits mid-range: a 20 mm bore gives 157.1 N push at 0.5 MPa, while a 32 mm bore reaches 402.1 N, so step up if your load needs more than about 147 N of working force. The 70 mm stroke is well inside the 150 mm maximum standard stroke for this bore. The female M6x1.0 rod thread takes I/Y knuckles, and FA/FB flange, LB foot or CA/CB clevis mounts bolt to the standard face. Remember the plain cylinder drifts when air is lost - add a rod lock or pilot check valve for held loads. Order ACE25X70 as the current replacement and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
Push is 245.4 N and pull 206.2 N at 0.5 MPa; at 0.7 MPa push rises to 343.6 N and pull to 288.6 N, with a theoretical maximum of 50.1 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, port M5x0.8, rod thread female M6x1.0.
Order ACE25X70, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 25 mm bore, 70 mm stroke and force class with a matching short body and mounting family, but confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to the DIN standard.
