This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X5B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X5B 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 ACP20X5B
The AirTAC Airtac ACP Compact Cylinder ACP20X5B 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 ACE20X5B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X5B
A double acting compact cylinder in the DIN-standard ACP series, the ACP20X5B pairs a 20 mm bore with a very short 5 mm stroke and a male threaded rod (the B code). At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, rising to 219.9 N push at 0.7 MPa, with a theoretical peak of 32 kgf at 1.0 MPa. The hard-anodized aluminium body and S45C hard-chrome rod run on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), moving at 30-500 mm/s with a fixed TPU bumper at each end.
Because the ISO 21287-class short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this model slots into tight clamping nests and small fixtures where a full-length body cannot. As a working figure, treat roughly 94 N (about 9.6 kg) as the usable push load at 0.5 MPa instead of the full 157.1 N rating. Note two buying points: the magnet is not fitted on this code, so position switches need the optional -S version with CMSE / DMSE sensors, and the ACP family is discontinued - the current-production drop-in is the ACE20X5, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X5B (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 ACE20X5B 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 ACP20X5B Is Used
Micro clamping in machining fixtures
The 5 mm stroke and 157.1 N push at 0.5 MPa are suited to short-travel hold-down clamps on small CNC jigs where the short body fits inside the fixture plate.
Eject or kick-off pins on assembly stations
A 219.9 N push at 0.7 MPa gives enough force to nudge small stamped or moulded parts off a nest, and the male rod thread takes a custom pin directly.
Indexing flag actuator on test benches
With the optional -S magnet and CMSE / DMSE switches, the 5 mm stroke can toggle a visible indicator or interlock flag on an electronics test rig.
Replacing the Airtac ACP Compact Cylinder ACP20X5B with the ACE20X5B
For a 5 mm stroke at this force level, compare the 16 mm bore (100.5 N push at 0.5 MPa) if the load is light, or step up to the 25 mm bore (245.4 N push) for more margin. A plain cylinder drifts when air is removed, so add a rod lock or pilot check valve if the position must hold. The male rod thread suits direct attachment to small tooling; FA/FB flange, LB foot or CA/CB clevis mounts bolt to the same face. Order the -S code if CMSE / DMSE switching is planned. Since ACP is discontinued, specify the ACE20X5 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE20X5B
- ✓ 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 ACP20X5B 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. It is double acting, runs at 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air, and has a 20 mm bore with a 5 mm stroke and a 10 mm rod with male thread.
No - the ACP family is discontinued. The current-production drop-in is the ACE20X5 (swap the P for an E), which matches the same bore, stroke and force class in the ISO 21287 short-body format. Confirm the ISO 21287 mounting dimensions against your fixture before ordering, since the ACP was built to the older DIN standard.
