This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X40B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X40B 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 ACP20X40B
The AirTAC Airtac ACP Compact Cylinder ACP20X40B is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X40B
The ACP20X40B is a double acting DIN-standard compact cylinder with a 20 mm bore and 40 mm stroke, male rod thread (B code) and PT port thread. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those rise to 219.9 N and 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits so well inside tight jigs and guarding.
This model is discontinued. The current-production drop-in is the ACE20X40 (swap the P for an E), which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN standard. Practical sizing: plan on about 94 N (roughly 9.6 kg of vertical lift, halved for a 2:1 margin) of real work at 0.5 MPa rather than the full 157.1 N rating. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends and no magnet fitted unless the -S code is ordered.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X40B (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 ACE20X40B 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 ACP20X40B Is Used
Bench-top press fixture
The 157.1 N push at 0.5 MPa is enough to seat small terminals or snap-fit caps in an electronics assembly jig, and the short body fits under a low press head.
Compact indexing stop
A 40 mm stroke is ideal for a raise-and-lower part stop on a small rotary indexing table, where the short ISO 21287-class body keeps the fixture footprint tight.
Carton flap tuck-down
On a semi-auto packaging bench, the 117.8 N pull force folds flaps or holds a lightweight part against a nest while glue or tape is applied.
Replacing the Airtac ACP Compact Cylinder ACP20X40B with the ACE20X40B
A 20 mm bore at 157.1 N push (0.5 MPa) suits light clamping and positioning; step down to a 16 mm bore (100.5 N) for smaller loads or up to a 25 mm bore (245.4 N) when you need more margin. The 40 mm stroke is well inside the 100 mm maximum standard stroke for this bore, so no made-to-order build is required. The male rod thread (B) pairs with I/Y knuckles on the ISO 21287 mounting face; FA/FB flange, LB foot and CA/CB clevis brackets are available. If you need position feedback, order the -S code to enable CMSE / DMSE switches - without it there is no magnet. Order the ACE20X40 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE20X40B
- ✓ 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 ACP20X40B FAQ
Push 157.1 N and pull 117.8 N at 0.5 MPa; push 219.9 N and pull 164.9 N at 0.7 MPa; theoretical maximum 32 kgf at 1.0 MPa. It is double acting with a 20 mm bore, 40 mm stroke, 10 mm rod, M5x0.8 port, male rod thread (B), operating pressure 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s and a fixed TPU bumper at both ends.
Order the ACE20X40, the ISO 21287 successor made by swapping the P for an E. It matches the same bore, stroke and force class and drops into the same short-body envelope, but confirm the ISO 21287 mounting dimensions before the swap because the ACP was a DIN-standard design. Also note the optional -S magnet code if you plan to fit CMSE or DMSE switches.
