This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE16X20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE16X20S 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 ACP16X20S
The AirTAC Airtac ACP Compact Cylinder ACP16X20S is a double acting DIN-standard tight/compact air cylinder with a Ø16mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE16X20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP16X20S
The ACP16X20S is a double acting DIN-standard compact cylinder with a 16 mm bore and 20 mm stroke, driven by air in both directions and stopped by a fixed TPU bumper 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 maximum of 20.5 kgf at 1.0 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures a full-length cylinder cannot reach.
This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the hard-anodized aluminium body to report rod position. As a rule of thumb, plan on about 60 N of usable push at 0.5 MPa, which vertically lifts roughly 6 kg with margin - enough to index small plastic housings or press light snap-fit parts. Note that ACP is discontinued: the current-production successor is the ACE16X20, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE16X20S (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 ACE16X20S 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 ACP16X20S Is Used
Small-part ejection from plastic molds
The 100.5 N push at 0.5 MPa is enough to kick finished caps or clips off a benchtop mold, and the 20 mm stroke matches shallow cavity depth.
Position-checked test fixtures
With the -S magnet fitted, a CMSE or DMSE switch confirms the rod is fully home before an electrical test starts on a PCB or connector.
Light clamping on assembly benches
About 6 kg of vertical lift equivalent holds small brackets or covers in place during a screwdriving or gluing step.
Replacing the Airtac ACP Compact Cylinder ACP16X20S with the ACE16X20S
For a 20 mm stroke at this force level, the 16 mm bore is a sensible middle choice: a 12 mm bore gives only 56.5 N push at 0.5 MPa, while a 20 mm bore delivers 157.1 N if your jig needs more margin. The rod end here is a female M4x0.7 thread on an 8 mm rod, and the port is M5x0.8. A plain cylinder drifts when air is lost, so add a rod lock or pilot check valve if the load must stay put. FA/FB flange, LB foot and CA/CB clevis mountings are available. Since ACP is discontinued, order the ACE16X20 as the drop-in replacement and verify the ISO 21287 hole pattern first.
Replacement checklist
- ✓ Current-production ACE → ACE16X20S
- ✓ 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 ACP16X20S 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, 20 mm stroke, 8 mm rod, M5x0.8 port, female M4x0.7 rod thread, 0.15-1.0 MPa (22-145 psi) operating pressure, 1.5 MPa (215 psi) proof pressure, -20 to +70 C temperature range and 30-500 mm/s speed. Fixed TPU bumpers sit at both ends.
Order the ACE16X20, the current-production ISO 21287 successor in the same bore, stroke and force class. The ACP is DIN-standard, so confirm the ISO 21287 mounting dimensions against your fixture before swapping. The ACE family also covers related types such as ASP/ATP single-acting, ACPD double-rod and ACPJ adjustable-stroke variants.
