This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X225S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X225S 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 ACPD50X225S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X225S 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 ACED50X225S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X225S
Double acting with a rod leaving both covers, the ACPD50X225S pushes and pulls with the same 881.2 N at 0.5 MPa (1233.7 N at 0.7 MPa) because both strokes work on the rod-side area. The 16 mm through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end, and speed runs 30-500 mm/s over 0.15-1.0 MPa (22-145 psi).
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 225 mm stroke fits tight gantries and sliding guards. Plan on roughly 529 N of real work at 0.5 MPa, which lifts about 45 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production drop-in is ACED50X225, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X225S (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 ACPD50X225S Is Used
Reciprocating conveyor pusher
The through-rod drives a pusher bar from one side while the rear rod carries a flag for a DMSE switch, indexing cartons at 881.2 N per stroke.
Twin-sided clamp fixture
Equal 1233.7 N at 0.7 MPa on both rod ends clamps a machining fixture symmetrically, with the 225 mm stroke clearing part loading in a tight cell.
Lift-assist press head
With about 45 kg of vertical lift capacity at a 2:1 margin, the double rod guides a small press head or nest without added anti-rotation hardware.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X225S with the ACED50X225S
At 50 mm bore you get 881.2 N both ways at 0.5 MPa; step down to ACPD40 for 571.8 N or up to ACPD63 for 1458.1 N if the load changes. The 225 mm stroke sits inside the 250 mm standard range for this bore, so no made-to-order build is needed. This unit carries the optional -S magnet, so CMSE / DMSE switches can be added for end-of-stroke sensing. Remember the piston drifts if air is lost - use a rod lock or pilot check where a load must be held. Order ACED50X225 as the replacement.
Replacement checklist
- ✓ Current-production ACE → ACED50X225S
- ✓ 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 ACPD50X225S FAQ
Because a rod exits both covers, force is equal in both directions: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, both ways. Maximum force at 1.0 MPa is 179.7 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi).
The hard-anodized aluminium body is an ISO 21287-class short build, roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, with FA/FB flange or LB foot mounting and a fixed TPU bumper at each end. The S in the model code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted for position sensing.
