This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X40 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.

About the Airtac ACP Compact Cylinder ACP20X40
The ACP20X40 is a double acting compact cylinder in the DIN-standard ACP series, with a 20 mm bore and 40 mm stroke on a 10 mm rod. Air drives the piston both ways, and fixed TPU bumpers at each end take the end-of-travel shock. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, rising to 219.9 N and 164.9 N at 0.7 MPa, with a theoretical peak of 32 kgf at 1.0 MPa. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit.
The hard-anodized aluminium body carries an S45C hard-chrome rod, and the two-way grease-storing piston seal keeps lubrication on the sealing face over a 30-500 mm/s speed range. In practical terms, plan on roughly 94 N (about 9.6 kg of force) of usable push at 0.5 MPa, which lifts about 8 kg vertically with a 2:1 margin. Note that this model is discontinued: the current-production drop-in is the ACE20X40, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. The magnet is not fitted on this code; order the -S version if you need CMSE or DMSE switch sensing.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X40 (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 ACE20X40 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 ACP20X40 Is Used
Bench-top press fixture
With 157.1 N push at 0.5 MPa, the 20 mm bore ejects pins and light press-fits on small electronics assembly benches, and the 40 mm stroke clears a 30 mm part stack.
Compact jig clamping
The short body saves about 50% of the length of an ISO 15552 profile cylinder, so the ACP20X40 clamps PCB or bracket workpieces inside narrow drill and rivet jigs.
Small carton push-off
Pushing roughly 9.6 kg of usable force at 0.5 MPa, this cylinder nudges lightweight cartons off a checkweigher lane where a larger bore would be oversized.
Replacing the Airtac ACP Compact Cylinder ACP20X40 with the ACE20X40
At 20 mm bore this sits in the light clamping class: the 16 mm bore gives 100.5 N push at 0.5 MPa if you need less, while the 25 mm bore delivers 245.4 N if your fixture needs more grip. The 40 mm stroke is well inside the 100 mm maximum standard stroke for this bore, so it ships as a standard build. Remember that a plain ACP20X40 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 mounts bolt to the same face family as the ACE20X40, the current replacement for this discontinued model.
Replacement checklist
- ✓ Current-production ACE → ACE20X40
- ✓ 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 ACP20X40 FAQ
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. The theoretical maximum is 32 kgf at 1.0 MPa. It is a double acting cylinder with a 20 mm bore, 40 mm stroke, 10 mm rod, M5x0.8 ports and a female M6x1.0 rod thread, running on 0.15-1.0 MPa (22-145 psi) air at 30-500 mm/s.
No - the ACP family is discontinued. The current-production drop-in is the ACE20X40, the ISO 21287 successor in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to the DIN standard. Mounting options such as FA/FB flange, LB foot and CA/CB clevis carry over, and the optional -S magnet enables CMSE or DMSE switches on the ACE equivalent.
