This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X5S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X5S 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 ACP20X5S
The AirTAC Airtac ACP Compact Cylinder ACP20X5S is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X5S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X5S
The ACP20X5S is a double acting DIN-standard compact cylinder with a 20 mm bore and a very short 5 mm stroke, fitted with the optional -S magnet so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke detection. It pushes 157.1 N and pulls 117.8 N at 0.5 MPa, rising to 219.9 N at 0.7 MPa, with a theoretical peak of 32 kgf at 1.0 MPa. The hard-anodized aluminium body carries M5x0.8 ports and the S45C hard-chrome rod ends in a female M6x1.0 thread.
Because the ISO 21287-class short body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, this unit slots into shallow fixtures, clamping bridges and slide assemblies where a full-length body cannot. Plan on about 94 N (roughly 9.6 kg) of real work at 0.5 MPa rather than the full 157.1 N rating, which means it lifts about 4.8 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production drop-in is the ACE20X5, so confirm ISO 21287 mounting dimensions before swapping. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with fixed TPU bumpers at both ends.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X5S (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 ACE20X5S 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 ACP20X5S Is Used
Micro clamping on SPC fixtures
The 5 mm stroke and 157.1 N push at 0.5 MPa suit short-travel swing clamps on CNC inspection fixtures, where the -S magnet feeds a CMSE switch to confirm the clamp is closed.
Eject pin on small plastic moulds
A 20 mm bore driving about 9.6 kg of usable thrust at 0.5 MPa nudges finished micro parts off shallow mould cavities without marking the surface.
Presence check on electronics assembly lines
The short body fits between PCB conveyor guides, and the fitted magnet with a DMSE switch verifies that a connector or bracket is seated in under 100 ms.
Replacing the Airtac ACP Compact Cylinder ACP20X5S with the ACE20X5S
At 20 mm bore this sits between the 16 mm size (100.5 N push at 0.5 MPa) and the 25 mm size (245.4 N push at 0.5 MPa), so step up if your clamp or press needs more than about 94 N of usable force. The 5 mm stroke is well inside the 100 mm maximum standard stroke for this bore. The female M6x1.0 rod thread accepts standard I/Y knuckles, and FA/FB flange, LB foot or CA/CB clevis mounts bolt to the same face. Remember that a plain unit drifts when air is lost, so add a rod lock or pilot check valve if the load must stay put. Order the ACE20X5 as the current replacement for this discontinued model.
Replacement checklist
- ✓ Current-production ACE → ACE20X5S
- ✓ 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 ACP20X5S 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; the theoretical maximum is 32 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s and temperature -20 to +70 C. For real work, budget about 94 N, roughly 9.6 kg equivalent, and about 4.8 kg vertical lift with a 2:1 margin.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow jigs and slides. Both ends carry fixed TPU bumpers that only decelerate the piston, so the rod drifts if air is lost. The ACP20X5S is discontinued; the current-production replacement is the ACE20X5 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before you swap.
