This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X150B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X150B 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 ACP25X150B is a double acting DIN-standard tight/compact air cylinder with a Ø25mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE25X150B (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP25X150B is a double acting DIN-standard compact cylinder with a 25 mm bore and 150 mm stroke, the maximum standard stroke for this bore. Air drives the piston both ways, a fixed TPU bumper sits at each end, and the B code gives a male rod thread on the 10 mm rod. At 0.5 MPa it pushes 245.4 N and pulls 206.2 N; at 0.7 MPa those rise to 343.6 N and 288.6 N, with a theoretical 50.1 kgf at 1.0 MPa. Its hard-anodized aluminium body runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and gantries. In practice, plan on roughly 147 N of usable push at 0.5 MPa, which lifts about 12 kg vertically with a 2:1 margin. This model is discontinued: the current-production drop-in is the ACE25X150, so confirm ISO 21287 mounting dimensions before swapping. The magnet is not fitted; order the -S code if you need CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X150B (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 ACE25X150B 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. |
| ×150 | 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 clamps aluminium or small steel workpieces in machining jigs, and the short body fits where a full-length profile cylinder cannot.
With 150 mm of stroke the rod can push cartons or trays off a conveyor lane, cycling at 30-500 mm/s between the fixed TPU bumpers.
The male rod thread (B code) bolts straight to I/Y knuckles for sliding covers and sample carriers, with about 12 kg vertical lift capacity at a 2:1 margin.
At 25 mm bore you get 245.4 N push at 0.5 MPa; step down to the 20 mm bore (157.1 N) for lighter clamping or up to the 32 mm bore (402.1 N) when the load grows. If the part must stay put when air is lost, add a rod lock or pilot check valve - a plain cylinder drifts. The 150 mm stroke is the standard maximum for this bore, so no made-to-order length is needed. Mount with FA/FB flange, LB foot or CA/CB clevis, and add the -S magnet code only if CMSE / DMSE sensing is required. For new projects, specify the ACE25X150 instead.
Replacement checklist
At 0.5 MPa it pushes 245.4 N and pulls 206.2 N; at 0.7 MPa it pushes 343.6 N and pulls 288.6 N, with a theoretical maximum of 50.1 kgf at 1.0 MPa. The model is discontinued; the current-production replacement is the ACE25X150 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.
It is a compact DIN-standard cylinder with a hard-anodized aluminium body, an S45C hard-chrome rod and a fixed TPU bumper at each end, saving about 50% of the mounting length of an ISO 15552 profile cylinder. Sensing is not included: order the -S magnet code to enable CMSE or DMSE reed or solid-state switches; without -S there is no magnet.
