This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X15B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X15B 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 ACP20X15B
The AirTAC Airtac ACP Compact Cylinder ACP20X15B is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 15mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X15B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X15B
A double acting compact cylinder in the DIN-standard ACP series, the ACP20X15B pairs a 20 mm bore with a short 15 mm stroke and a male rod thread (the B code) on a 10 mm hard-chrome S45C rod. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures, guarding and slide assemblies where a full-length body will not fit. Air supply is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and speed runs 30-500 mm/s with fixed TPU bumpers at both ends.
At 0.5 MPa this bore pushes 157.1 N and pulls 117.8 N; at 0.7 MPa expect 219.9 N push and 164.9 N pull, with a theoretical ceiling of 32 kgf at 1.0 MPa. In practice plan on about 94 N of usable work at 0.5 MPa, which lifts roughly 8 kg vertically with a 2:1 margin - enough for small clamps, part ejection and gate indexing. Note this unit ships without a magnet: order the -S code if you need CMSE / DMSE switch sensing. The ACP family is discontinued; the current-production drop-in is ACE20X15, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X15B (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 ACE20X15B 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 ACP20X15B Is Used
Small-part press fitting
The 157.1 N push at 0.5 MPa seats bearings, bushings or terminals into plastic housings on electronics assembly benches, with the 15 mm stroke matching shallow press depth.
Gate indexing on compact fixtures
Fits jig plates and gantry slides where a full-length body will not go; the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder.
Carton flap tuck and eject
On packaging machines the 20 mm bore flicks flaps or pushes light cartons off a chute, lifting about 8 kg vertically with a 2:1 margin at 0.5 MPa.
Replacing the Airtac ACP Compact Cylinder ACP20X15B with the ACE20X15B
Size against real forces: the 16 mm bore delivers 100.5 N push at 0.5 MPa, while the 25 mm bore steps up to 245.4 N - pick the 20 mm when your load sits between those two. Remember a plain ACP drifts when air is lost, so add a rod lock or pilot check valve if the load must hold position. Mounting options include FA/FB flange, LB foot and CA/CB clevis, and the optional -S magnet enables CMSE / DMSE switches. For new builds, specify the ACE20X15 instead, as this ACP model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACE20X15B
- ✓ 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 ACP20X15B FAQ
At 0.5 MPa: 157.1 N push and 117.8 N pull. At 0.7 MPa: 219.9 N push and 164.9 N pull. Theoretical maximum is 32 kgf at 1.0 MPa. The cylinder is double acting, runs 30-500 mm/s on air filtered to 40 um, and carries a fixed TPU bumper at each end. It is discontinued, so confirm the ACE20X15 as your replacement.
Sensing requires the optional -S magnet code; this base model has no magnet, so CMSE or DMSE reed and solid-state switches only work when -S is ordered. Mounting uses FA/FB flange, LB foot and CA/CB clevis brackets on the ISO 21287-class face. Before swapping from the discontinued ACP, verify the ISO 21287 dimensions of the ACE20X15 against your fixture.
