This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X5H — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X5H 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 ACP20X5H
The AirTAC Airtac ACP Compact Cylinder ACP20X5H is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X5H (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X5H
A double acting DIN-standard compact cylinder, the ACP20X5H pairs a 20 mm bore with a very short 5 mm stroke for small indexing and clamping moves in cramped fixtures. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, and its hard-anodized aluminium body with S45C hard-chrome rod keeps the envelope tight. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into jigs and guards a full-length cylinder cannot reach.
Plan on about 94 N of usable force at 0.5 MPa rather than the full 157.1 N rating, which corresponds to lifting roughly 8 kg vertically with a 2:1 margin. The fixed TPU bumper at each end only decelerates the piston; it never holds a load when air is lost. This model is discontinued, and the current-production drop-in is the ACE20X5 - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X5H (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 ACE20X5H 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 ACP20X5H Is Used
Small-part ejection on a press die
The 157.1 N push at 0.5 MPa is enough to kick a stamped washer or terminal off the die face, and the 5 mm stroke keeps the unit inside the die shoe.
Fixture clamp for PCB test racks
About 94 N of practical clamping force at 0.5 MPa holds a populated circuit board against a locating stop during in-circuit testing.
Short-lift gate on a packaging sensor station
With the optional -S magnet and a DMSE switch, the 5 mm stroke confirms gate position on a carton check station; lift capacity is roughly 8 kg vertically.
Replacing the Airtac ACP Compact Cylinder ACP20X5H with the ACE20X5H
For a 5 mm stroke at this force level, compare the 16 mm bore (100.5 N push at 0.5 MPa) if space is tighter, or step up to the 25 mm bore (245.4 N push) for heavier clamping. The 20 mm bore tops out at a 100 mm standard stroke, so 5 mm is well inside range. Mounting options include FA/FB flange, LB foot and CA/CB clevis; the optional -S magnet enables CMSE / DMSE switches, and without -S there is no magnet. Replacement: ACE20X5.
Replacement checklist
- ✓ Current-production ACE → ACE20X5H
- ✓ 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 ACP20X5H 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 is 32 kgf at 1.0 MPa. It is a 20 mm bore, 5 mm stroke double acting compact cylinder with M5x0.8 ports, a 10 mm rod with female M6x1.0 thread, 0.15-1.0 MPa (22-145 psi) operating pressure, 30-500 mm/s speed and fixed TPU bumpers at both ends.
Order the ACE20X5, the ISO 21287 successor made by swapping the P for an E. It matches the same bore, stroke and force class and drops into the same FA/FB flange, LB foot or CA/CB clevis family, but because the ACP was DIN-standard you should confirm the ISO 21287 mounting dimensions before the swap.
