This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE25X15 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE25X15 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 ATP25X15 is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø25mm bore and 15mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE25X15 (ISO 21287 ACE), in the same bore, stroke and force class.
A single acting compact pull cylinder, the ATP25X15 uses an internal spring to hold the rod extended and compressed air at 0.2 MPa or more to retract it over a 15 mm stroke. At 0.5 MPa it delivers 170.9 N of pull net of the spring (253.3 N at 0.7 MPa), so it suits light clamping and return-to-home tasks in the 25 mm bore class. The hard-anodized aluminium body with an S45C hard-chrome 10 mm rod carries a fixed TPU bumper at each end.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it drops into tight jigs and guarding where a full-length body will not fit. In practice, plan on roughly 103 N of usable pull at 0.5 MPa - about 10 kgf, or around 5 kg of vertical lift with a 2:1 margin - when matching it to a real part weight. Note this model is discontinued: the current-production replacement is the ATE25X15, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE25X15 (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. |
| ×15 | 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 spring keeps the pin extended for part loading; 170.9 N of air pull at 0.5 MPa retracts it 15 mm clear of the workpiece before machining.
Fails to extended on air loss, so the gate stays open and cartons pass safely; 0.2 MPa minimum pressure is enough to cycle it closed.
The 15 mm stroke and about 5 kg vertical-lift margin suit lightweight specimen trays that must spring back to home between tests.
Size against the 25 mm bore's 170.9 N pull at 0.5 MPa: step down to a 20 mm bore (88.1 N) for lighter latches, or up to a 32 mm bore (296.0 N) if the spring must overcome more drag. Because the spring returns the rod to its extended home on air loss, the ATP25X15 does not hold a mid-stroke position - pick a double-acting ACP/ACE if you need to stop mid-travel. This version has a female M6x1.0 rod thread and PT ports; there is no magnet fitted, so position sensing with CMSE / DMSE switches requires ordering the optional -S code. For new builds, specify the ATE25X15 instead.
Replacement checklist
It is a single acting pull cylinder: the spring extends the rod and air retracts it. Pull is 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa, both net of the return spring. A practical planning figure is about 103 N of usable pull at 0.5 MPa - roughly 10 kgf, or about 5 kg of vertical lift with a 2:1 margin. Operating range is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, speed 50-500 mm/s, and the M5x0.8 port takes air filtered to 40 um.
Only if the optional -S magnet is ordered - this ATP25X15 code has no magnet, so no CMSE or DMSE switch can be mounted as-is. The model itself is discontinued; the current-production drop-in is the ATE25X15 (same 25 mm bore, 15 mm stroke and force class). Confirm the ISO 21287 mounting dimensions against your fixture before swapping, and use FA/FB flange, LB foot or CA/CB clevis brackets to match the mounting face.
