This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE25X25 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE25X25 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 ATP Single Acting Port Compact Cylinder ATP25X25 is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø25mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE25X25 (ISO 21287 ACE), in the same bore, stroke and force class.
A single acting pull cylinder with spring return, the ATP25X25 uses its internal spring to extend the 10 mm rod and compressed air to retract it, so the rod sits normally extended and fails to the extended position when air is lost. At 0.5 MPa the net pull (already minus the spring) is 170.9 N, rising to 253.3 N at 0.7 MPa; the minimum working pressure is 0.2 MPa, which is what it takes to beat the spring. The 25 mm stroke is well inside the 150 mm standard limit for this bore, and rod speed runs 50-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures, gates and clamping nests. In practice the 170.9 N pull supports about 102 N (roughly 10 kg) of real work at 0.5 MPa, and with a 2:1 margin it lifts about 8 kg vertically - enough to retract a small slide or lift a light cover. The hard-anodized aluminium body carries a fixed TPU bumper at both ends, and the female M6x1.0 rod thread takes standard I/Y knuckles. Note: this model is discontinued; the current-production successor is the ATE25X25, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE25X25 (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 | Pull force (spring return) |
|---|---|
| 0.5 MPa | 170.9 N |
| 0.7 MPa | 253.3 N |
Single-acting pull: the spring extends the rod; air retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.
| ATP | DIN compact cylinder (single-acting pull, spring-return, discontinued). |
|---|---|
| 25 | Bore size in mm. |
| ×25 | 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).
Spring extends the rod to raise a small machine guard or inspection lid about 8 kg vertically; applying 0.2-0.5 MPa air pulls it back down for access.
On a packaging machine indexing slide, the 170.9 N net pull at 0.5 MPa retracts the carriage to home, while the spring pushes it out to the pick position between cycles.
In a drill jig, the spring holds the clamp arm open and a 0.5 MPa air signal (253.3 N at 0.7 MPa available) pulls the arm to release the workpiece for unloading.
Size by net pull: at 0.5 MPa the 25 mm bore gives 170.9 N, while the smaller 20 mm bore manages 88.1 N and the larger 32 mm bore reaches 296.0 N - pick 25 mm when a light gate or slide needs a positive return-to-home spring. Remember the spring cannot hold a mid-stroke position; on air loss the rod goes fully extended. The rod end is female M6x1.0 and the port is M5x0.8. This unit has no magnet; if you need CMSE or DMSE switch sensing, order the -S variant instead. Since the ATP25X25 is discontinued, plan the swap to the ATE25X25 and verify the ISO 21287 mounting dimensions first.
Replacement checklist
Net of the return spring, the 25 mm bore pulls 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 50-500 mm/s, rod 10 mm with female M6x1.0 thread, port M5x0.8, stroke 25 mm (standard up to 150 mm for this bore), air filtered to 40 um. The model is discontinued; the ATE25X25 is the current replacement.
The compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow pockets, gantries and guard frames where a full-length body will not. A fixed TPU bumper at each end decelerates the rod at the ends of travel; it is a passive pad, not an adjustable air device, and it never locks or holds a load. Mounting options include FA/FB flange, LB foot and CA/CB clevis, and the optional -S magnet enables CMSE / DMSE switches.
