This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X50S 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.
Airtac ACPD Double Rod Compact Cylinder ACPD50X50S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X50S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 50mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X50S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X50S
Double acting with a rod leaving both covers, the ACPD50X50S pushes and pulls with the same 881.2 N at 0.5 MPa (1233.7 N at 0.7 MPa) because each stroke works on the rod-side area. The 16 mm through-rod resists rotation and side load, and the rear rod can carry a sensor flag. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly on the body.
The hard-anodized aluminium body keeps the mounting length about 50% shorter than an ISO 15552 profile cylinder, which suits tight jigs and gantry frames. A fixed TPU bumper sits at each end, and speed spans 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Note the ACPD family is discontinued: the current-production drop-in is the ACED50X50, so confirm ISO 21287 mounting dimensions before swapping. As a rule of thumb, plan on roughly 529 N of usable work at 0.5 MPa, which lifts about 45 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X50S (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.
Theoretical Output Force (Ø50mm)
| 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).

Where the Airtac ACPD Double Rod Compact Cylinder ACPD50X50S Is Used
Reciprocating transfer carriage
The rear rod balances the front rod on a shuttle that slides parts between two conveyor stations, with 881.2 N available in each direction over the 50 mm travel.
Clamp-and-eject fixture
A CNC fixture uses the front rod to clamp an aluminium housing while the back rod drives an ejector pin, both fed by the same 50 mm bore at 0.5 MPa.
Position-flagged press station
With the -S magnet fitted, a DMSE switch on the body confirms end-of-stroke on a small benchtop marking press running at 30-500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X50S with the ACED50X50S
At 881.2 N per side, the 50 mm bore sits between the 40 mm bore (571.8 N at 0.5 MPa) and the 63 mm bore (1458.1 N at 0.5 MPa); step up if your fixture needs more than about 529 N of working force. The 50 mm stroke is well inside the 250 mm maximum standard stroke for this bore. Air ports are 1/8" PT and the rod end carries a female M10x1.5 thread. Because a plain through-rod cylinder drifts when air is lost, add a rod lock or pilot check for a held load. Order the ACED50X50 as the current replacement and verify its ISO 21287 footprint.
Replacement checklist
- ✓ Current-production ACE → ACED50X50S
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPD Double Rod Compact Cylinder ACPD50X50S FAQ
Because a rod exits both covers, output is equal both ways: 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), and speed 30-500 mm/s. The bore is 50 mm with a 16 mm rod and a 1/8" PT port.
AirTAC no longer produces the ACPD family. The current-production successor is the ACED50X50, an ISO 21287 compact cylinder in the same bore, stroke and force class. Before swapping, confirm the ISO 21287 mounting dimensions against your existing fixture, since the ACP was built to a DIN-standard footprint. FA/FB flange and LB foot mounts remain available on the replacement.
