This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X45 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X45 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 ACP20X45
The ACP20X45 is a double acting DIN-standard compact cylinder with a 20 mm bore and 45 mm stroke. At 0.5 MPa it delivers 157.1 N on the push stroke, and its short ISO 21287-class body saves roughly 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. Air supply is filtered to 40 um, pressure runs 0.15-1.0 MPa (22-145 psi), and rod speed spans 30-500 mm/s.
Built around a hard-anodized aluminium body with an S45C hard-chrome rod, this model carries a fixed TPU bumper at both ends and a female M6x1.0 rod thread with an M5x0.8 port. In practice, plan on about 94 N of usable push force at 0.5 MPa, which means it lifts roughly 8 kg vertically with a 2:1 margin. Note that this model is discontinued: the current-production replacement is the ACE20X45, a drop-in successor in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X45 (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 ACE20X45 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 ACP20X45 Is Used
Small-parts clamping fixture
A 94 N usable push at 0.5 MPa is enough to hold aluminium brackets or plastic housings in a CNC drilling jig, with the 45 mm stroke clearing the part for loading.
Lab sample ejector
The compact short body fits inside benchtop test rigs where a full-length profile cylinder cannot, pushing sample trays or vials out of a fixture at 30-500 mm/s.
Carton flap tucker
On a light packaging line, the 20 mm bore closes small carton flaps or pushes product into a sleeve, lifting about 8 kg vertically with a 2:1 margin.
Replacing the Airtac ACP Compact Cylinder ACP20X45 with the ACE20X45
For a 45 mm stroke at this force level, the 20 mm bore gives 157.1 N push at 0.5 MPa. Step down to the 16 mm bore (100.5 N) for lighter clamping, or move to the 25 mm bore (245.4 N) if the load grows. The 45 mm stroke sits well inside the 100 mm maximum standard stroke for this bore, so it is a catalogue item. If the load must stay put when air is lost, add a rod lock or pilot check valve, since a plain cylinder will drift. Choose the -S code if you need the optional magnet for CMSE / DMSE switches; without it there is no magnet. Mount with FA/FB flange, LB foot or CA/CB clevis. This model is discontinued, so order the ACE20X45 and confirm the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE20X45
- ✓ 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 ACP20X45 FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa it pushes 219.9 N and pulls 164.9 N. Theoretical maximum is 32 kgf at 1.0 MPa. It is a double acting compact cylinder, 20 mm bore, 45 mm stroke, 10 mm rod with female M6x1.0 thread, M5x0.8 port, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a fixed TPU bumper at both ends.
Order the ACE20X45, the current-production ISO 21287 successor: swap the P for an E and you get the same bore, stroke and force class in a matching short body. The ACE accepts FA/FB flange, LB foot and CA/CB clevis mountings plus I/Y rod knuckles on the standard face. Before swapping, confirm the ISO 21287 mounting dimensions against your fixture, because the ACP was built to the DIN standard. Also remember the magnet is the optional -S code, not a default feature.
