This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X150B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X150B 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 ACP20X150B

About the Airtac ACP Compact Cylinder ACP20X150B
The ACP20X150B is a double acting compact cylinder in the DIN-standard ACP series, with a 20 mm bore pushing 157.1 N and pulling 117.8 N at 0.5 MPa (219.9 N / 164.9 N at 0.7 MPa, 32 kgf theoretical maximum). Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slides into tight jigs and guarding where a full-length body cannot. The B code gives a male rod thread on the 10 mm rod, and the PT port is M5x0.8.
Note that the 150 mm stroke exceeds the 100 mm maximum standard stroke for a 20 mm bore, so this unit is made to order. The hard-anodized aluminium body carries a fixed TPU bumper at each end, and the S45C hard-chrome rod runs on a two-way grease-storing seal at 30-500 mm/s. Plan on about 94 N (roughly 9.6 kg) of usable push at 0.5 MPa, or about 8 kg of vertical lift with a 2:1 margin. This model is discontinued; the current-production drop-in is ACE20X150, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X150B (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 ACE20X150B 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 ACP20X150B Is Used
Compact ejection station
The 157.1 N push at 0.5 MPa ejects small stamped clips from a jig, and the short body fits inside the fixture plate where a full-length cylinder would overhang.
Small-parts press fit
About 9.6 kg of usable working force at 0.5 MPa presses bushings into plastic housings on an assembly bench, with the 150 mm made-to-order stroke reaching deep into the nest.
Guiderail deflector
On a bottle-line conveyor, the male rod thread drives a swing deflector to divert cartons between lanes, running at 30-500 mm/s under the 0.15-1.0 MPa (22-145 psi) supply.
Replacing the Airtac ACP Compact Cylinder ACP20X150B with the ACE20X150B
At 0.5 MPa this 20 mm bore delivers 157.1 N of push; if your load needs more, step up to the 25 mm bore at 245.4 N, and if less force and a shorter body suit, the 16 mm bore gives 100.5 N. The 150 mm stroke is a made-to-order length above the 100 mm standard cap for this bore. Choose the B male rod thread for external knuckles and tooling, and add the -S code only if you need the optional magnet for CMSE / DMSE switches - without it no magnet is fitted. A plain cylinder drifts when air is lost, so specify a rod lock or pilot check valve for held loads. Order ACE20X150 as the current replacement and verify ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE20X150B
- ✓ 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 ACP20X150B FAQ
Push is 157.1 N and pull 117.8 N at 0.5 MPa; 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. It is double acting, 20 mm bore with a 10 mm rod, M5x0.8 PT port, male rod thread (B), operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, and a fixed TPU bumper at both ends. The 150 mm stroke is non-standard for this bore (standard cap 100 mm) and is made to order.
Order ACE20X150, the ISO 21287 successor in the same bore, stroke and force class. The ACP is DIN-standard, so confirm the ISO 21287 mounting dimensions against your fixture before swapping. If you also need position feedback, order the ACE with the magnet option so CMSE / DMSE switches can be fitted.
