This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X50 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 ACP20X50
The AirTAC Airtac ACP Compact Cylinder ACP20X50 is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 50mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X50 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X50
A double acting compact cylinder with a 20 mm bore and 50 mm stroke, the ACP20X50 pushes 157.1 N and pulls 117.8 N at 0.5 MPa, rising to 219.9 N on the extend stroke at 0.7 MPa. Its hard-anodized aluminium body with an S45C hard-chrome rod runs on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, with a fixed TPU bumper at each end. This model is discontinued; the current-production drop-in is ACE20X50.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures where a full-length body cannot. For real-world sizing, treat roughly 94 N (about 0.6 of the push force) as the usable working force at 0.5 MPa, which corresponds to lifting about 9 kg vertically - halve that for a 2:1 margin and match it against your part weight. FA/FB flange, LB foot and CA/CB clevis brackets bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X50 (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 ACE20X50 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 ACP20X50 Is Used
Small-part clamping on CNC fixtures
The 157.1 N push at 0.5 MPa holds aluminum or plastic workpieces in machining jigs, and the short body fits between fixture walls where a full-length cylinder would not.
Push-off on electronics assembly lines
With a 50 mm stroke and 30-500 mm/s speed, it nudges PCB trays or connector bins off a conveyor, and the optional -S magnet with CMSE switches confirms end positions.
Lab and test-rig actuation
The 20 mm bore delivers about 9 kg of vertical lift capability at 0.5 MPa, enough for raising light probes or gates in compact benchtop test stations.
Replacing the Airtac ACP Compact Cylinder ACP20X50 with the ACE20X50
At 157.1 N push at 0.5 MPa, the 20 mm bore suits clamping and positioning of light-to-medium parts; step down to the 16 mm bore (100.5 N) for tighter spaces or up to the 25 mm bore (245.4 N) when more force is needed. The 50 mm stroke sits well inside the 100 mm maximum standard stroke for this bore, so it is a catalog item. Note that a plain cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must hold. Order the -S code if you need the magnet for CMSE / DMSE switches, and confirm ISO 21287 mounting dimensions before swapping to the ACE20X50 replacement.
Replacement checklist
- ✓ Current-production ACE → ACE20X50
- ✓ 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 ACP20X50 FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa it pushes 219.9 N and pulls 164.9 N. The theoretical maximum is 32 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed spans 30-500 mm/s.
No - the ACP family is discontinued. The current-production drop-in is ACE20X50, which matches the same 20 mm bore, 50 mm stroke and force class in the ISO 21287 short body. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to the DIN standard.
