This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X80 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X80 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 ACPD50X80
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X80 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 80mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X80 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X80
Double acting with a rod leaving both covers, the ACPD50X80 pushes and pulls with identical force because both strokes work on the rod-side area: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa in either direction. The 16 mm through-rod resists rotation and side load, carries a sensor flag on the rear end if needed, and the fixed TPU bumper at each end absorbs the stroke. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it cycles at 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 jigs and gantries. Note the magnet is not fitted on this code; the optional -S version accepts CMSE / DMSE switches. This model is discontinued - the current-production ACED50X80 is the drop-in successor in the same bore, stroke and force class, so confirm ISO 21287 mounting dimensions before swapping. As a sizing rule of thumb, plan on about 529 N (roughly 54 kgf) of usable push at 0.5 MPa, which lifts about 27 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X80 (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 ACPD50X80 Is Used
Bench fixture clamping
The symmetric through-rod clamps a machined aluminium housing in a drill jig from both sides, delivering 881.2 N at 0.5 MPa in whichever direction the fixture needs.
Pusher on a packaging line
Mounted under a carton conveyor, the 80 mm stroke kicks boxes onto a side lane at up to 500 mm/s, with the rear rod doubling as a position-flag mount.
Slide transfer in an electronics assembly cell
Bolted to an LB foot bracket, the double rod drives a small linear slide between two pick positions, where equal force both ways keeps cycle timing identical in each direction.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X80 with the ACED50X80
At 881.2 N per direction at 0.5 MPa, the 50 mm bore suits clamping and transfer work in the 50 kg class; step down to the 40 mm bore (571.8 N) for lighter fixtures or up to the 63 mm bore (1458.1 N) when the load grows. The 80 mm stroke sits well inside the 250 mm maximum standard stroke for this bore. Remember the piston drifts if air is lost - add a rod lock or pilot check where a load must stay put. Female M10x1.5 rod thread, PT ports, FA/FB flange or LB foot mounting, and the -S code if you later want CMSE / DMSE sensing. For new builds, order the ACED50X80 instead, as this ACPD version is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACED50X80
- ✓ 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 ACPD50X80 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 per direction, 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 bore takes a 1/8" port with an M10x1.5 female rod thread.
No - the ACPD family is discontinued. The current-production replacement is the ACED50X80 (swap the P for an E), which matches the same 50 mm bore, 80 mm stroke and force class on the short ISO 21287 body. Before swapping, confirm the ISO 21287 mounting dimensions against your fixture, since the ACP was built to the older DIN-standard format. If you need position sensing, order the -S magnet code so CMSE / DMSE switches can be fitted.
