This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE16X40B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE16X40B 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 ACP16X40B
The AirTAC Airtac ACP Compact Cylinder ACP16X40B is a double acting DIN-standard tight/compact air cylinder with a Ø16mm 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 ACE16X40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP16X40B
The ACP16X40B is a double acting compact cylinder in the DIN-standard ACP series, with a 16 mm bore and 40 mm stroke. 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 small gantries. At 0.5 MPa it delivers 100.5 N on the push stroke and 75.4 N on the pull stroke; at 0.7 MPa those rise to 140.7 N and 105.6 N, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The B code gives a male rod thread on the 8 mm rod, and the port is M5x0.8.
A practical sizing rule: at 0.5 MPa the usable push force is about 60 N, which corresponds to lifting roughly 6 kg vertically - halve that to about 3 kg if you want a 2:1 margin against a real part weight. The hard-anodized aluminium body carries an S45C hard-chrome rod, a fixed TPU bumper sits at both ends, and speed spans 30-500 mm/s over 0.15-1.0 MPa (22-145 psi). Note that this model is discontinued; the current-production drop-in is the ACE16X40, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE16X40B (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 ACE16X40B 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 ACP16X40B Is Used
Small-parts ejection on assembly fixtures
The 100.5 N push at 0.5 MPa is enough to kick stamped terminals or plastic caps off a nest, and the 40 mm stroke keeps the tooling plate shallow.
Compact gating on packaging lines
With the optional -S magnet and CMSE switches, the rod position can be signalled to the PLC even where the short body leaves no room for external switches.
Sample clamping in lab automation
About 6 kg of practical vertical capacity at 0.5 MPa suits holding microplate trays or vial racks in compact analytical instruments.
Replacing the Airtac ACP Compact Cylinder ACP16X40B with the ACE16X40B
For a 40 mm stroke at this force level, compare the 12 mm bore (56.5 N push at 0.5 MPa) if your load is lighter, or step up to the 20 mm bore (157.1 N push) if you need more headroom. Remember that a plain ACP does not hold position when air is lost - add a rod lock or pilot check valve for a held load. If you need CMSE or DMSE switches, order the -S variant, since the magnet is only fitted with the optional -S code; this version has none. FA/FB flange, LB foot and CA/CB clevis mountings fit the standard face. Buy the ACE16X40 instead - it is the current replacement in the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACE16X40B
- ✓ 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 ACP16X40B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa it pushes 140.7 N and pulls 105.6 N; theoretical maximum is 20.5 kgf at 1.0 MPa. It is double acting with a 16 mm bore, 40 mm stroke, 8 mm male-thread rod, M5x0.8 port, 0.15-1.0 MPa (22-145 psi) operating pressure, 30-500 mm/s speed and a fixed TPU bumper at each end.
Order the ACE16X40, the ISO 21287 successor made by swapping the P for an E. It matches the same bore, stroke and force class with a short body, but because the ACP was DIN-standard you should confirm the ISO 21287 mounting dimensions against your fixture before the swap.
