This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X225 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X225 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 ACPD50X225
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X225 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 225mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X225 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X225
A double acting compact cylinder with a rod leaving both covers, the ACPD50X225 pushes and pulls with identical force: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa in either direction, because both strokes work on the rod-side area. The 50 mm bore drives a 16 mm through-rod over a 225 mm stroke at 30-500 mm/s, and the short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight machine frames and sliding guards.
The through-rod resists rotation and side load and gives a symmetric mount, while the rear rod can carry a sensor flag on a pick-and-place gantry. At 0.5 MPa, plan on about 529 N of usable work (roughly 54 kg vertical lift, or about 27 kg with a 2:1 margin) rather than the full rating. A fixed TPU bumper pads both ends, the hard-anodized aluminium body carries 1/8" ports, and the rod end is female M10x1.5. Note: this model is discontinued; the current-production drop-in is the ACED50X225, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X225 (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 ACPD50X225 Is Used
Symmetric press fixture
Equal 881.2 N force in both directions lets one cylinder clamp a machined housing from either side of a drilling jig without reversing the port plumbing.
Gantry transfer slide
The 225 mm stroke and 16 mm through-rod move plastic trays between two conveyor lanes, with the rear rod carrying a position flag for the controller.
Lift-assist ejector
About 27 kg of vertical lift with a 2:1 margin at 0.5 MPa suits pushing finished cartons down off a packaging machine chute.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X225 with the ACED50X225
Size between the 40 mm bore (571.8 N at 0.5 MPa) and the 63 mm bore (1458.1 N at 0.5 MPa); the 50 mm sits in the middle at 881.2 N each way. If a load must stay put when air is lost, add a rod lock or pilot check - a plain through-rod cylinder drifts. FA/FB flange or LB foot mounting bolts to the ISO 21287 face, and CMSE / DMSE switches need the optional -S magnet code, which this model does not carry. For new builds, order the ACED50X225 instead, the current successor in the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACED50X225
- ✓ 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 ACPD50X225 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 peak of 179.7 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, and temperature -20 to +70 C.
It is a short-body compact cylinder whose mounting length is about 50% less than an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB flange or LB foot options. The ACPD family is discontinued; the current drop-in is the ACED50X225 (same 50 mm bore, 225 mm stroke and force class). Confirm the ISO 21287 mounting dimensions before you swap.
