This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE32X20B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE32X20B 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 ACP32X20B
The AirTAC Airtac ACP Compact Cylinder ACP32X20B 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 ACE32X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP32X20B
A double acting compact cylinder with a 32 mm bore and a short 20 mm stroke, the ACP32X20B carries a male rod thread (the B code) and a 1/8" port. At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa those figures rise to 563 N and 483.8 N, with a theoretical ceiling of 82 kgf at 1.0 MPa. Its hard-anodized aluminium body and S45C hard-chrome rod run on filtered air at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to +70 C.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight fixtures such as press-fit stations and gate clamps. Plan on about 241 N of real work at 0.5 MPa (roughly 60% of the rated push), enough to lift about 20 kg vertically with a 2:1 margin. Note that this model is discontinued: the current drop-in is ACE32X20, so confirm ISO 21287 mounting dimensions before swapping. Fixed TPU bumpers sit at both ends, and the optional -S magnet (not fitted on this code) enables CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE32X20B (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 ACE32X20B 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 ACP32X20B Is Used
Bench-top crimping press
The 402.1 N push at 0.5 MPa crimps small terminals and connectors on electronics assembly benches, with the 20 mm stroke matching short press heads.
Carton flap tucker
Mounted via FB flange on a packaging line, the male rod thread drives a flap-tucking blade that folds box tops before sealing.
Parts presence check fixture
With the optional -S magnet and CMSE switches, the cylinder confirms part seating in an automotive bracket checking gauge, retracting 345.6 N at 0.5 MPa.
Replacing the Airtac ACP Compact Cylinder ACP32X20B with the ACE32X20B
For a 20 mm stroke in this force band, the 32 mm bore gives 402.1 N push at 0.5 MPa; if your load is lighter, a 25 mm bore (245.4 N push) saves space, while a 40 mm bore (628.3 N push) adds headroom. The male rod thread (B) suits rod knuckles and external tooling; FA/FB flange, LB foot or CA/CB clevis mounts bolt to the same face. Remember the piston drifts when air is lost, so add a rod lock or pilot check valve for held loads. Order ACE32X20 instead - this ACP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACE32X20B
- ✓ 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 ACP32X20B FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa, 563 N push and 483.8 N pull; theoretical maximum is 82 kgf at 1.0 MPa. Bore is 32 mm, stroke 20 mm, rod 12 mm, port 1/8" PT, speed 30-500 mm/s, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi).
Order ACE32X20, the current-production ISO 21287 successor: swap the P for an E and you get the same bore, stroke and force class with a matching short body and mounting family. Confirm the ISO 21287 mounting dimensions against your fixture before the swap, and add -S to the code if you need the optional magnet for CMSE / DMSE switches.
