This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE32X20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE32X20S 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 ACP32X20S
The AirTAC Airtac ACP Compact Cylinder ACP32X20S is a double acting DIN-standard tight/compact air cylinder with a Ø32mm bore and 20mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE32X20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP32X20S
The ACP32X20S is a double acting DIN-standard compact cylinder with a 32 mm bore and a short 20 mm stroke, fitted with the optional -S magnet so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke detection. At 0.5 MPa it pushes with 402.1 N and pulls with 345.6 N, and its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs, guards and gantries where a full-length body simply will not fit.
Built with a hard-anodized aluminium body, an S45C hard-chrome piston rod and a fixed TPU bumper at both ends, it runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) with a speed range of 30-500 mm/s. For planning, treat roughly 240 N (about 24 kg of vertical lift) as the usable push at 0.5 MPa rather than the full rating. Note that this model is discontinued: the current-production drop-in is the ACE32X20, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE32X20S (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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
The ACE32X20S 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 ACP32X20S Is Used
Fixture clamping on CNC machining centres
The 402.1 N push at 0.5 MPa clamps aluminium or small steel workpieces in dedicated jigs, and the 20 mm stroke keeps the envelope minimal inside crowded fixture plates.
Position-verified part ejection
With the -S magnet and a DMSE switch, a packaging line can confirm the ejector has fully extended before the next carton indexes into place.
Compact press-fit of bushings
A short-stroke bench fixture for pressing small bushings into housings uses the 563 N push at 0.7 MPa, with the short body fitting under a low gantry frame.
Replacing the Airtac ACP Compact Cylinder ACP32X20S with the ACE32X20S
Size both ways before ordering: the 25 mm bore delivers 245.4 N push at 0.5 MPa, while the 40 mm bore reaches 628.3 N, so the 32 mm bore at 402.1 N sits in the middle for medium clamping and positioning jobs. The 20 mm stroke is well inside the 200 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order build. Remember that a plain cylinder of this type drifts when air is lost - for a held load add a rod lock or pilot check valve. FA/FB flange, LB foot and CA/CB clevis mounts bolt straight to the ISO 21287 face, and the -S magnet on this unit pairs with CMSE / DMSE switches. Since the ACP32X20S is discontinued, order the ACE32X20 as the current replacement and verify the ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACE32X20S
- ✓ 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 ACP32X20S FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa push rises to 563 N and pull to 483.8 N. The theoretical maximum at 1.0 MPa is 82 kgf. A practical rule is to plan on about 60% of the 0.5 MPa push - roughly 240 N, or about 24 kg of vertical lift - so the cylinder is never run at its limit.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits where space is tight. The S in the model code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clamped on for stroke-end signals. This model is discontinued; the ACE32X20 is the current drop-in successor in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before you swap.
