This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED80X55S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED80X55S 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 ACPD80X55S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD80X55S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø80mm bore and 55mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED80X55S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD80X55S
Double acting with a rod leaving both covers, the ACPD80X55S pushes and pulls with identical force because each stroke works on the rod-side area: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa in either direction. The 80 mm bore carries a 20 mm through-rod, 1/4" ports and a female M12x1.75 rod thread, 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 gantries and guarding where a full-length body cannot.
The S code means the optional -S magnet is fitted on this unit, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the tube for end-of-stroke signalling. The through-rod resists rotation and side load, and the rear rod is a handy carrier for a sensor flag. A fixed TPU bumper sits at each end and the body is hard-anodized aluminium with an S45C hard-chrome rod. Note this model is discontinued: the current-production drop-in is ACED80X55, same bore, stroke and force class, so confirm ISO 21287 mounting dimensions before swapping. As a sizing guide, keep real work near 1414 N at 0.5 MPa, which corresponds to lifting about 120 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED80X55S (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 ACPD80X55S Is Used
Reciprocating press transfer
The equal 2356.2 N push and pull at 0.5 MPa lets one 80 mm cylinder clamp a steel bracket on the forward stroke and eject it on the return, with the rear rod driving a flag past a DMSE switch for cycle counting.
Pallet lift-and-lower column
A through-rod 80 mm bore lifting about 120 kg vertically with margin, guided by the second rod end on a linear bushing, suits short-stroke 55 mm raise/lower stations on packaging line infeed tables.
Dual-side gate actuator
With a rod exiting both covers, a sliding machine guard or diverter gate can be driven from either face of the cylinder, keeping the 1/4" ported body buried inside the frame where space is short.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD80X55S with the ACED80X55S
At 80 mm bore you sit near the top of the compact range: 2356.2 N per direction at 0.5 MPa, with the 63 mm bore (1458.1 N) below and the 100 mm bore (3681.6 N) above if you need more force. Stroke 55 mm is well inside the 300 mm standard limit for this bore. Choose LB foot or FA/FB flange mounting to suit the fixture, and remember a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. Since ACPD80X55S is discontinued, order ACED80X55 as the current equivalent and verify the ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACED80X55S
- ✓ 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 ACPD80X55S FAQ
Because it is a double-rod cylinder, output is equal both ways: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa on every stroke, with a maximum of 480.5 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
No - the ACPD family is discontinued. The current-production drop-in is ACED80X55 (swap the P for an E), which matches the same 80 mm bore, 55 mm stroke and force class in the ISO 21287 short-body format. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to a DIN standard.
