This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED80X50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED80X50S 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 ACPD80X50S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD80X50S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø80mm bore and 50mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED80X50S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD80X50S
Double acting with a rod leaving both covers, the ACPD80X50S pushes and pulls with identical output: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa in either direction, because both strokes work on the rod-side area. The 80 mm bore carries a 20 mm through-rod with a female M12x1.25 rod thread on this model, and the S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the hard-anodized aluminium body. Air supply runs 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof limit, speed is 30-500 mm/s, and a fixed TPU bumper sits at each end.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why this size suits tight press fixtures and sliding guards. In practice, plan on about 1414 N of usable push at 0.5 MPa, and for vertical work the rod will lift roughly 120 kg with a 2:1 margin. Note that this model is discontinued: the current-production drop-in is the ACED80X50, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED80X50S (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 (Ø80mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 2356 N |
| 0.7 MPa | 3299 N |
| Max (@1.0 MPa) | 481 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 ACPD80X50S Is Used
Bench-top press fixture
The 2356.2 N symmetric output at 0.5 MPa suits a small stamping or riveting head on a compact jig where a full-length profile cylinder will not fit.
Reciprocating conveyor pusher
Equal force in both directions moves cartons off a line at up to 500 mm/s, and the rear rod carries a flag for CMSE switch position feedback.
Vertical part lowerer
With about 120 kg of vertical lift at a 2:1 margin, the through-rod lowers castings into a machining fixture from a gantry guard.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD80X50S with the ACED80X50S
At 80 mm bore you are in the 2356.2 N class at 0.5 MPa both ways. If your load needs under 881.2 N, the ACPD50 saves air and money; if it needs up to 3681.6 N, step to the 100 mm bore. The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag. LB foot or FA/FB flange mounting plus the fitted -S magnet for CMSE / DMSE switches covers most positioning jobs. Remember the piston drifts if air is lost, so add a rod lock or pilot check for a held load. Order the ACED80X50 as the current replacement and verify the ISO 21287 footprint.
Replacement checklist
- ✓ Current-production ACE → ACED80X50S
- ✓ 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 ACPD80X50S FAQ
Because a rod exits both covers, force is equal both ways: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa, with a maximum of 480.5 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.
A fixed TPU pad at each cover simply decelerates the piston at end of travel; it is not adjustable and never holds a load. The S in the model code means the optional -S magnet is fitted on this unit, so CMSE or DMSE reed or solid-state switches can be mounted on the body. This model is discontinued; the ACED80X50 is the current drop-in, so confirm ISO 21287 mounting dimensions before ordering.
