This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X125 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X125 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 ACP20X125
The AirTAC Airtac ACP Compact Cylinder ACP20X125 is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 125mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X125 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X125
The ACP20X125 is a double acting DIN-standard compact cylinder with a 20 mm bore and a 125 mm stroke, driving a 10 mm hard-chrome rod through a female M6x1.0 thread. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, rising to 219.9 N / 164.9 N at 0.7 MPa, with a theoretical ceiling of 32 kgf at 1.0 MPa. Air supply runs 0.15-1.0 MPa (22-145 psi) and rod speed 30-500 mm/s.
Its hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so it slots into tight fixtures and gantry frames. Note that the 125 mm stroke exceeds the 100 mm standard maximum for bore 20, so it is made to order. As a rule of thumb, plan on about 94 N of usable push at 0.5 MPa - roughly 9 kg of vertical lift with a 2:1 margin. This model is discontinued; the current-production drop-in is ACE20X125, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X125 (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 ACE20X125 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 ACP20X125 Is Used
Small-part ejection on assembly benches
The 157.1 N push at 0.5 MPa is enough to kick stamped terminals or plastic caps off a fixture, and the short body fits under low bench frames.
Lab sample press and dispensing stations
About 9 kg of usable vertical push at 0.5 MPa suits light pressing of vials, lids and test coupons where a full-length cylinder will not fit.
Carton flap tucking on packaging lines
The 125 mm stroke reaches across a carton face to fold flaps, with the fixed TPU bumper softening each end of the 30-500 mm/s travel.
Replacing the Airtac ACP Compact Cylinder ACP20X125 with the ACE20X125
Size against neighbours: bore 16 gives 100.5 N push at 0.5 MPa, while bore 25 reaches 245.4 N - pick 20 mm when your load sits between those. Remember the piston drifts when air is lost, so add a rod lock or pilot check valve if the load must stay put. The 125 mm stroke is non-standard for this bore and built to order. Mounting options include FA/FB flange, LB foot and CA/CB clevis; the optional -S magnet enables CMSE / DMSE switches, and without -S no magnet is fitted. For new projects, order ACE20X125 instead - same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACE20X125
- ✓ 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 ACP20X125 FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa, 219.9 N push and 164.9 N pull; theoretical maximum 32 kgf at 1.0 MPa. Bore 20 mm, stroke 125 mm (non-standard, made to order), rod 10 mm with female M6x1.0 thread, port M5x0.8, operating pressure 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, fixed TPU bumper both ends.
No - the ACP family is discontinued. The current-production replacement is ACE20X125 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since ACP was built to the DIN standard.
