This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X75 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 ACPD50X75
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X75 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 75mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X75 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X75
This is a double acting compact cylinder with a rod leaving BOTH covers, so the 50 mm bore delivers the same 881.2 N at 0.5 MPa (1233.7 N at 0.7 MPa) whichever end you push from, 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 stroke speed runs 30-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarding. At 0.5 MPa plan on about 529 N (roughly 54 kg) of usable push, or halve the 89.8 kgf equivalent for a 2:1 margin and it lifts about 45 kg vertically. Note: this model is DISCONTINUED - the current-production drop-in is the ACED50X75, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X75 (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 ACPD50X75 Is Used
Reciprocating transfer slide
A 75 mm shuttle on a packaging line moves trays between two pick points; the rear rod carries a flag for a DMSE switch when the -S magnet is ordered, and the 881.2 N stroke handles the tray weight with margin.
Symmetric press fixture
A bench-top staking jig for electronics enclosures needs equal force from either side of the die; the 50 mm bore gives 1233.7 N at 0.7 MPa in both directions, and the short body fits inside the guard.
Rotary index lock-out pin
A dial-plate indexing station uses the through-rod to push an interlock pin in and out with identical 881.2 N force, mounted on an LB foot bracket inside a cramped machine frame.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X75 with the ACED50X75
For a 75 mm stroke needing about 880 N per direction, bore 50 is the right pick; bore 40 gives 571.8 N at 0.5 MPa and bore 63 gives 1458.1 N if you need more headroom. The through-rod keeps force equal both ways, so no derating for the return stroke. Remember the piston drifts if air is lost - add a rod lock or pilot check to hold a load. FA/FB flange or LB foot mounts bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches (this code has no magnet). Order the ACED50X75 for new projects.
Replacement checklist
- ✓ Current-production ACE → ACED50X75
- ✓ 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 ACPD50X75 FAQ
Because a rod exits both covers, output is equal in both directions: 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 50 mm bore takes a 1/8" port with an M10x1.5 female rod thread.
The ACPD family is out of production; the current drop-in is the ACED50X75 (swap the P for an E) in the same bore, stroke and force class. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange or LB foot brackets bolt to the ISO 21287 face - confirm the mounting dimensions against your fixture before swapping, since the ACP was built to a DIN standard.
