This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X80B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X80B 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 ACP Compact Cylinder ACP20X80B
The AirTAC Airtac ACP Compact Cylinder ACP20X80B is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 80mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X80B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X80B
The ACP20X80B is a double acting compact cylinder in the DIN-standard ACP series, with a 20 mm bore and an 80 mm stroke on a 10 mm rod ending in a male thread (the B code). At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those figures rise to 219.9 N and 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi), speed runs 30-500 mm/s, and both ends carry a fixed TPU bumper.
Its hard-anodized aluminium body is an ISO 21287 short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. As a working rule, plan on roughly 94 N of usable push at 0.5 MPa (about 0.6 of the rating), which corresponds to lifting around 8 kg vertically with a 2:1 margin. Note that this model is discontinued: the current-production drop-in is the ACE20X80, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X80B (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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 kgf | |
The ACE20X80B produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP20X80B Is Used
Lab sample handling
Pushes sample trays of up to about 8 kg between test stations in compact analytical equipment, where the short ISO 21287 body fits inside tight enclosures.
Blister pack ejection
The 80 mm stroke ejects finished blister cards from a forming station on a small pharmaceutical packaging line at up to 500 mm/s.
Clamp-and-index fixture
Male rod thread accepts an I-type knuckle to swing a clamp arm on a CNC jig, using roughly 94 N of practical holding force at 0.5 MPa.
Replacing the Airtac ACP Compact Cylinder ACP20X80B with the ACE20X80B
Size check: a 16 mm bore gives 100.5 N push at 0.5 MPa, while stepping up to 25 mm yields 245.4 N - choose 20 mm when your load sits between those bands. The 80 mm stroke is within the 100 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order build. This unit has no magnet fitted; if you need CMSE or DMSE switches, order the -S variant instead. Remember the piston drifts when air is lost, so add a rod lock or pilot check valve for held loads. For new projects, specify the ACE20X80 replacement.
Replacement checklist
- ✓ Current-production ACE → ACE20X80B
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACP Compact Cylinder ACP20X80B FAQ
Push is 157.1 N and pull is 117.8 N at 0.5 MPa; at 0.7 MPa it reaches 219.9 N push and 164.9 N pull, with a theoretical maximum of 32 kgf at 1.0 MPa. It is double acting with a 20 mm bore, 80 mm stroke, 10 mm male-threaded rod, M5x0.8 ports, 0.15-1.0 MPa (22-145 psi) operating pressure and 30-500 mm/s speed.
Order the ACE20X80, the current ISO 21287 successor made by swapping the P for an E. It matches the same bore, stroke and force class, but because the ACP was built to a DIN standard, verify the ISO 21287 mounting dimensions against your fixture before committing to the swap.
