This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE16X125B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE16X125B 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 ACP16X125B
The AirTAC Airtac ACP Compact Cylinder ACP16X125B is a double acting DIN-standard tight/compact air cylinder with a Ø16mm 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 ACE16X125B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP16X125B
A double acting compact cylinder in the DIN-standard ACP series, the ACP16X125B pairs a 16 mm bore with a 125 mm stroke and a male rod thread (the B code). Air drives the piston both ways, and a fixed TPU bumper sits at each end. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those rise to 140.7 N and 105.6 N, with a theoretical peak of 20.5 kgf at 1.0 MPa. The 125 mm stroke is longer than the 75 mm standard maximum for this bore, so it is a made-to-order build.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits slim pick-and-place heads and enclosed test rigs. In practice, plan on roughly 60 N (about 6 kg) of usable push at 0.5 MPa, or size a vertical lift at around 5 kg with a 2:1 margin. Note this unit is discontinued: the current-production drop-in is the ACE16X125, so confirm the ISO 21287 mounting dimensions before swapping. No magnet is fitted; the optional -S code adds one for CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE16X125B (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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | 106 N |
| Max (@1.0 MPa) | 21 kgf | |
The ACE16X125B 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 ACP16X125B Is Used
Small-part ejection from plastic moulds
The 100.5 N push at 0.5 MPa is enough to strip lightweight moulded clips and caps off shallow cores, and the 125 mm reach clears deep cavities on a compact tool.
Sample transfer in laboratory automation
With about 5 kg of vertical lift capacity at a 2:1 margin, the 8 mm rod handles reagent trays and slide racks between stations inside tight analyser enclosures.
Carton flap tucking on packaging lines
Running at 30-500 mm/s, the long 125 mm stroke folds tall flap panels on small cartons where a full-length cylinder would not fit behind the guarding.
Replacing the Airtac ACP Compact Cylinder ACP16X125B with the ACE16X125B
At 100.5 N push at 0.5 MPa, this 16 mm bore covers light clamping and small part transfer. Step down to a 12 mm bore (56.5 N) for tiny fixtures, or up to a 20 mm bore (157.1 N) when parts run heavier. The 125 mm stroke exceeds the 75 mm standard limit for bore 16, so order it as a non-standard build and allow lead time. The male rod thread (B) suits external knuckles; FA/FB flange, LB foot and CA/CB clevis mountings bolt to the same face. A plain cylinder drifts when air is lost, so add a rod lock or pilot check valve for held loads. For new projects, specify the ACE16X125 instead.
Replacement checklist
- ✓ Current-production ACE → ACE16X125B
- ✓ 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 ACP16X125B FAQ
Push is 100.5 N and pull 75.4 N at 0.5 MPa; at 0.7 MPa push is 140.7 N and pull 105.6 N, with a theoretical maximum of 20.5 kgf at 1.0 MPa. It is a double acting 16 mm bore, 125 mm stroke compact cylinder with an 8 mm male rod thread, M5x0.8 ports, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, and a fixed TPU bumper at both ends. The 125 mm stroke is a non-standard, made-to-order length since bore 16 tops out at 75 mm standard.
No - the ACP series is discontinued. The current-production replacement is the ACE16X125 (swap the P for an E), which matches the same bore, stroke and force class in the ISO 21287 short-body format. Before swapping, confirm the ISO 21287 mounting dimensions against your fixture, since the ACP was built to the older DIN standard. If you need position feedback, order the -S magnet code so CMSE or DMSE switches can be fitted; without -S there is no magnet in the piston.
