This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X15B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X15B 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 ACPD Double Rod Compact Cylinder ACPD50X15B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 15mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X15B (ISO 21287 ACE), in the same bore, stroke and force class.
A double acting compact cylinder with a rod leaving both covers, the ACPD50X15B delivers the same 881.2 N at 0.5 MPa (1233.7 N at 0.7 MPa) whether it pushes or pulls, because both strokes work on the rod-side area. The 16 mm through-rod resists rotation and side load, gives a symmetric mounting point at each end, and the rear rod can carry a sensor flag. A fixed TPU bumper sits in both covers, and speed runs 30-500 mm/s.
The hard-anodized aluminium body follows the short ISO 21287 format, cutting roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and gantries. Practical sizing: plan on about 529 N (roughly 54 kgf) of real work at 0.5 MPa, and expect it to lift about 44 kg vertically with a 2:1 margin. Note that this model is discontinued - the current-production drop-in is the ACED50X15, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X15B (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).
| ACPD | DIN compact cylinder (double-rod, discontinued). |
|---|---|
| 50 | 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 through-rod drives a slide from either end with identical 881.2 N force at 0.5 MPa in both directions, ideal for a short-stroke pick-and-place shuttle on a packaging line.
The rear rod can mount a flag for a proximity sensor on a bottling machine gate, giving a symmetric actuator with a 15 mm stroke and fixed TPU bumpers at each end.
A machining fixture can clamp a workpiece from two opposing points using one double-rod body, each side applying about 54 kgf of usable force at 0.5 MPa.
For a 50 mm bore job needing equal force in both directions, this 15 mm stroke unit gives 881.2 N at 0.5 MPa each way. If the load is lighter, the ACPD40X15B offers 571.8 N at 0.5 MPa; if you need more, step up to the ACPD63X15B at 1458.1 N. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. Mounting brackets (FA/FB flange, LB foot, CA/CB clevis and more) bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches; this unit has no S code, so no sensor can be fitted. Order the ACED50X15 as the current replacement.
Replacement checklist
No - because a rod exits both covers, both strokes use the rod-side area, so force is equal in each direction: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, with a maximum of 179.7 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is 1/8" (PT thread).
The ACPD family is no longer in production. The current drop-in is the ACED50X15 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class. Before swapping, confirm the ISO 21287 mounting dimensions, since the ACP was built to the older DIN-standard format. Also note this unit has no magnet; on either series, order the -S code if you want CMSE / DMSE switch capability.
