This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X40S 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 ACP20X40S
The AirTAC Airtac ACP Compact Cylinder ACP20X40S is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X40S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X40S
Double acting on both strokes, the ACP20X40S is AirTAC's DIN-standard compact cylinder with a 20 mm bore and 40 mm stroke. 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. 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 sensing. Its hard-anodized aluminium body and S45C hard-chrome rod run on filtered air at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits cramped jigs and guarding. In practice, plan on about 94 N (roughly 9 kg of thrust) for real work at 0.5 MPa, or expect it to lift about 8 kg vertically once a 2:1 margin is applied. Note this model is discontinued: the current-production successor is ACE20X40, a drop-in in the same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X40S (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 ACE20X40S 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 ACP20X40S Is Used
Small-parts press fitting
With about 94 N of usable thrust at 0.5 MPa, this bore seats bushings, dowel pins and terminals into plastic housings on electronics assembly benches where space is tight.
Position-verified clamping
The fitted -S magnet lets CMSE or DMSE switches confirm clamp and release on fixture nests for small machined brackets, cutting scrap from unclamped parts.
Light vertical lifting
Halving the 16 kgf theoretical lift gives about 8 kg of vertical capacity with margin - enough to raise chutes or gates on packaging and labelling machines.
Replacing the Airtac ACP Compact Cylinder ACP20X40S with the ACE20X40S
If 157.1 N of push at 0.5 MPa is marginal for your load, step up to the 25 mm bore (245.4 N); if you need less force and a smaller envelope, the 16 mm bore delivers 100.5 N. The 40 mm stroke sits well inside the 100 mm maximum standard stroke for this bore, so it is a catalogue item. Choose the female M6x1.0 rod thread as coded here, or order the B variant for a male thread. Remember that a plain cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must be held. For new designs, specify ACE20X40 instead, since ACP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACE20X40S
- ✓ 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 ACP20X40S FAQ
Push is 157.1 N and pull 117.8 N at 0.5 MPa; at 0.7 MPa push is 219.9 N and pull 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. It is double acting with a 20 mm bore, 40 mm stroke, 10 mm rod, M5x0.8 ports, M6x1.0 female rod thread, fixed TPU bumpers at both ends, and runs at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s and -20 to +70 C.
Order ACE20X40: swap the P for an E and you get the current-production ISO 21287 compact cylinder in the same bore, stroke and force class. The short body still saves about half the mounting length of an ISO 15552 profile cylinder, and FA/FB flange, LB foot and CA/CB clevis mountings bolt to the standard face. Because the ACP was DIN-standard, verify the ISO 21287 mounting dimensions before the swap.
