This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE25X70B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE25X70B 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 ACP25X70B 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 ACE25X70B (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP25X70B is a double acting DIN-standard compact cylinder with a 25 mm bore and 70 mm stroke, pushing 245.4 N and pulling 206.2 N at 0.5 MPa (343.6 N / 288.6 N at 0.7 MPa, up to 50.1 kgf theoretical at 1.0 MPa). Air filtered to 40 um drives it across 0.15-1.0 MPa (22-145 psi), with speeds of 30-500 mm/s and a fixed TPU bumper at each end. The B code gives a male rod thread on the 10 mm rod; the port is M5x0.8.
Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit. For sizing, treat about 147 N (roughly 15 kg) as the usable push force at 0.5 MPa - in vertical terms that lifts about 12 kg with a 2:1 margin. Note this model is discontinued: the current-production drop-in is the ACE25X70, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE25X70B (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 ACE25X70B 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).
With 245.4 N push at 0.5 MPa and a short 70 mm body, this cylinder clamps workpieces inside crowded machining fixtures where a full-length body cannot reach.
The 70 mm stroke ejects small cartons or trays from chutes at up to 500 mm/s, and the M5x0.8 port keeps plumbing compact on dense manifolds.
About 15 kg of usable push force at 0.5 MPa seats vials and microplate lids gently in diagnostic equipment, with the male rod thread taking a knuckle directly.
At 25 mm bore you sit mid-range: a 20 mm bore delivers 157.1 N push at 0.5 MPa, while a 32 mm bore reaches 402.1 N - step up if your tooling mass approaches the 15 kg usable-load mark. The 70 mm stroke is well inside the 150 mm standard limit for this bore. The male rod thread (B) suits I/Y rod knuckles; FA/FB flange, LB foot and CA/CB clevis brackets bolt to the mounting face. If you need position feedback, order the -S variant to enable CMSE / DMSE switches - this code has no magnet. Remember a plain cylinder drifts when air is lost, so add a rod lock or pilot check valve for held loads. Order the ACE25X70 as the current replacement.
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, and the fluid must be air filtered to 40 um. The 10 mm rod carries a male thread and the port is M5x0.8.
No - the ACP family is discontinued. The current-production successor is the ACE25X70 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class. Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions against your fixture before ordering the swap.
