This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X120S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X120S 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 ACP20X120S

About the Airtac ACP Compact Cylinder ACP20X120S
The ACP20X120S is a double acting compact cylinder built to the DIN-standard short-body format, with a 20 mm bore, a 120 mm stroke and a 10 mm hard-chrome S45C piston rod. Its hard-anodized aluminium body and threaded aluminium covers keep the mounting length about 50% shorter than an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those rise to 219.9 N and 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The 120 mm stroke exceeds the 100 mm standard maximum for this bore, so it is a made-to-order build.
The S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the body for end-of-stroke signalling. A fixed TPU bumper sits at both ends to soften arrival, but it never locks or holds a load - if the valve centres or air is lost the piston drifts, so add a rod lock or pilot check valve where holding matters. This model is discontinued: the current-production drop-in is the ISO 21287 ACE20X120 in the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X120S (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 ACE20X120S 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 ACP20X120S Is Used
Electronics fixture clamping
The short ISO 21287 body fits inside crowded PCB test fixtures, and 157.1 N of push at 0.5 MPa holds boards against locating pins without over-clamping.
Gantry pick-and-place with position feedback
With the -S magnet fitted, CMSE or DMSE switches confirm extend and retract on a 120 mm stroke, ideal for small-part transfer heads on automated assembly cells.
Small-part ejection from stamping dies
About 8 kg of practical vertical thrust at 0.5 MPa is enough to kick finished bushings or spacers off a die table, and the fixed TPU bumper softens each cycle at 30-500 mm/s.
Replacing the Airtac ACP Compact Cylinder ACP20X120S with the ACE20X120S
Size against the neighbours: a 16 mm bore gives 100.5 N push at 0.5 MPa, while a 25 mm bore raises it to 245.4 N, so the 20 mm sits between them for light-to-medium clamping and positioning. As a rule of thumb, plan on about 94 N of usable work at 0.5 MPa (roughly 0.6 of the rated push), which is enough to lift about 8 kg vertically - halve that for a comfortable 2:1 margin on real part weights. The female M6x1.0 rod thread takes standard I/Y knuckles, and FA/FB flange, LB foot or CA/CB clevis mountings bolt to the ISO 21287 face. Order the -S magnet (fitted here) whenever CMSE or DMSE switches are needed. For new projects, specify the ACE20X120 instead, as this ACP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACE20X120S
- ✓ 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 ACP20X120S 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; theoretical maximum is 32 kgf at 1.0 MPa. It is double acting with a 20 mm bore, 120 mm made-to-order stroke, 10 mm rod, M5x0.8 ports, 0.15-1.0 MPa (22-145 psi) operating range, 1.5 MPa (215 psi) proof pressure, -20 to +70 C temperature, and 30-500 mm/s speed.
Order the ACE20X120, the current-production ISO 21287 successor: swap the P for an E and you get the same bore, stroke and force class in a matching short body. Because the ACP was built to the DIN standard, confirm the ISO 21287 mounting dimensions before swapping. The ACE family also covers related types such as ASP/ATP, ACPD and ACPJ.
