This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X90 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X90 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 ACP20X90
The AirTAC Airtac ACP Compact Cylinder ACP20X90 is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 90mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X90 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X90
Double acting with air powering both the extend and return stroke, the ACP20X90 is a DIN-standard compact cylinder with a 20 mm bore and 90 mm stroke. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those figures rise to 219.9 N and 164.9 N, with a theoretical 32 kgf at 1.0 MPa. The hard-anodized aluminium body carries an S45C hard-chrome rod, and fixed TPU bumpers sit at both ends.
Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. In practice, plan on about 94 N of usable push at 0.5 MPa, which lifts roughly 8 kg vertically with a 2:1 margin. Note that this model is discontinued: the current-production replacement is ACE20X90, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X90 (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 ACE20X90 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 ACP20X90 Is Used
Small-part ejection on CNC fixtures
The 90 mm stroke and 157.1 N push at 0.5 MPa knock finished aluminium brackets off a machining fixture, and the short body fits inside the fixture base where a full-length cylinder cannot.
Carton pusher on a packaging line
With about 94 N of usable working force at 0.5 MPa, the cylinder diverts lightweight cartons between conveyor lanes at speeds up to 500 mm/s.
Sample press in a lab automation cell
The 20 mm bore delivers 219.9 N at 0.7 MPa to seat sample vials into a test rack, and the compact body mounts under the deck of a benchtop analyzer.
Replacing the Airtac ACP Compact Cylinder ACP20X90 with the ACE20X90
Size both ways: if 157.1 N push at 0.5 MPa is more than the job needs, the 16 mm bore (100.5 N) saves space; if the load demands more, step up to the 25 mm bore (245.4 N). A plain ACP20X90 does not hold position when air is lost - the piston drifts - so add a rod lock or pilot check valve for held loads. The female M6x1.0 rod thread and PT ports suit standard fittings, and FA/FB flange, LB foot or CA/CB clevis mounting bolts to the same face. If you need position sensing, order the -S code for the optional magnet; without it no CMSE or DMSE switch can be fitted. For new projects, specify ACE20X90, the current drop-in successor.
Replacement checklist
- ✓ Current-production ACE → ACE20X90
- ✓ 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 ACP20X90 FAQ
At 0.5 MPa the 20 mm bore pushes 157.1 N and pulls 117.8 N. At 0.7 MPa it reaches 219.9 N push and 164.9 N pull. The theoretical maximum is 32 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and speed spans 30-500 mm/s.
Sensing requires the optional -S magnet code; the base ACP20X90 has no magnet, so CMSE or DMSE switches cannot be mounted unless you order -S. The model itself is discontinued - the current-production replacement is ACE20X90, a drop-in successor in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping.
