This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X30S 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 ACP20X30S
The AirTAC Airtac ACP Compact Cylinder ACP20X30S is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 30mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X30S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X30S
The ACP20X30S is a double acting compact cylinder in the DIN-standard ACP series, with a 20 mm bore and 30 mm stroke driving a 10 mm hard-chrome S45C rod. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, rising to 219.9 N push at 0.7 MPa. Its hard-anodized aluminium body with threaded aluminium covers keeps the mounting length roughly half that of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body cannot. The S in the code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling.
Practical sizing: treat about 94 N (0.6 of the push figure) as the usable force at 0.5 MPa, which corresponds to lifting roughly 8 kg vertically with a 2:1 margin. Both ends carry a fixed TPU bumper that only decelerates the piston - it never holds a load if air is lost, so add a rod lock or pilot check valve for that. Note this model is discontinued: the current-production drop-in is the ACE20X30 (ISO 21287), same bore, stroke and force class - confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X30S (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 ACE20X30S 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 ACP20X30S Is Used
Small-part clamping fixture
The 157.1 N push at 0.5 MPa clamps aluminium brackets or plastic housings in a CNC second-op jig, with the 30 mm stroke clearing part loading quickly.
Position feedback on a test rig
Because the -S magnet is fitted, CMSE or DMSE switches confirm extend and retract on an automated leak-test station without external proximity sensors.
Bench-top press assist
Roughly 8 kg of vertical lift capacity with a 2:1 margin suits ejecting small stamped parts from a manual press die at 30-500 mm/s.
Replacing the Airtac ACP Compact Cylinder ACP20X30S with the ACE20X30S
At 20 mm bore this sits mid-range: a 16 mm bore gives 100.5 N push at 0.5 MPa if the load is lighter, while a 25 mm bore delivers 245.4 N for heavier clamping. Stroke 30 mm is well inside the 100 mm maximum standard stroke for this bore, so it is a catalogue item. Mounting options include FA/FB flange, LB foot and CA/CB clevis, and the fitted -S magnet accepts CMSE / DMSE switches. Since ACP is discontinued, order the ACE20X30 as the current replacement and verify the ISO 21287 mounting footprint against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACE20X30S
- ✓ 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 ACP20X30S FAQ
Push 157.1 N and pull 117.8 N at 0.5 MPa; push 219.9 N and pull 164.9 N at 0.7 MPa; theoretical maximum 32 kgf at 1.0 MPa. It is double acting with a 20 mm bore, 30 mm stroke, 10 mm rod, M6x1.0 female rod thread, M5x0.8 ports, 0.15-1.0 MPa (22-145 psi) operating range, 1.5 MPa (215 psi) proof pressure, -20 to +70 C temperature, 30-500 mm/s speed and fixed TPU bumpers at both ends.
Order the ACE20X30, the ISO 21287 successor made by swapping the P for an E. It matches the same 20 mm bore, 30 mm stroke and force class with a short-body design, but because the ACP was DIN-standard you should confirm the ISO 21287 mounting dimensions against your fixture before swapping. The ACE also accepts the optional -S magnet for CMSE / DMSE switches.
