This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X80S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X80S 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 ACP20X80S

About the Airtac ACP Compact Cylinder ACP20X80S
The ACP20X80S is a double acting DIN-standard compact cylinder with a 20 mm bore and 80 mm stroke, driving a 10 mm hard-chrome S45C rod through an M6x1.0 female thread. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those rise to 219.9 N and 164.9 N, with a theoretical ceiling of 32 kgf at 1.0 MPa. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding where a full-length body cannot. The -S code on this model means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the body for end-of-stroke sensing.
In practice, plan on about 94 N of usable push at 0.5 MPa - roughly 60% of the rated figure - which corresponds to lifting about 8 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries M5x0.8 ports, runs on 0.15-1.0 MPa (22-145 psi) of filtered air at 30-500 mm/s, and uses fixed TPU bumpers at both ends. Note that this model is discontinued: the current-production replacement is the ACE20X80, so confirm the ISO 21287 mounting dimensions before you swap.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X80S (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 ACE20X80S 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 ACP20X80S Is Used
Small-part ejection from plastic moulds
The 157.1 N push at 0.5 MPa clears lightweight moulded clips and caps from shallow cavities, while the 80 mm stroke reaches into a press frame that a full-length body cannot enter.
Position-verified test fixtures
With the fitted -S magnet, CMSE or DMSE switches confirm clamp and release positions on an electronics test bench, cutting cycle faults on PCB bed-of-nails rigs.
Bench-top crimping of wire terminals
About 94 N of usable force at 0.5 MPa crimps small-gauge spade terminals on an assembly bench, with the short body mounted under the tooling plate on an FB flange.
Replacing the Airtac ACP Compact Cylinder ACP20X80S with the ACE20X80S
At 20 mm bore this sits between the 16 mm (100.5 N push at 0.5 MPa) and the 25 mm (245.4 N push at 0.5 MPa); if your load needs more than about 94 N of real work, step up to the 25 mm. The 80 mm stroke is within the 100 mm standard range for this bore, so no made-to-order stroke is needed. Because the piston drifts when air is lost, add a rod lock or pilot check valve if the load must stay put. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the same face, and the -S magnet on this unit accepts CMSE / DMSE switches. Order the ACE20X80 as the current drop-in successor.
Replacement checklist
- ✓ Current-production ACE → ACE20X80S
- ✓ 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 ACP20X80S FAQ
At 0.5 MPa the 20 mm bore delivers 157.1 N push and 117.8 N pull; 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. Derate to about 94 N of practical push at 0.5 MPa - roughly 8 kg of vertical lift with a 2:1 margin. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
The hard-anodized aluminium body is an ISO 21287-class compact build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot and CA/CB clevis options on the same face. Each end carries a fixed TPU bumper that simply decelerates the piston - it is not a load lock, so use a rod lock or pilot check valve to hold position. The ACP20X80S is discontinued; the ACE20X80 is the current-production replacement in the same bore, stroke and force class, but confirm the ISO 21287 mounting dimensions before swapping since the ACP was built to a DIN standard.
