This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE20X5 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE20X5 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 ASP Single Acting Guided Compact Cylinder ASP20X5
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP20X5 is a single acting, push (spring return) 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 ASE20X5 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP20X5
A single acting push cylinder with spring return, the ASP20X5 uses a 20 mm bore and a very short 5 mm stroke: air extends the rod and the internal spring pulls it back home. At 0.5 MPa it delivers 127.4 N of push, already net of the spring, rising to 190.2 N at 0.7 MPa, and it starts working from just 0.2 MPa. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped fixtures where a full-length body simply will not fit.
For sizing, treat roughly 76 N (about 0.6 of the rated push) as the usable working force at 0.5 MPa, which corresponds to lifting about 6 kg vertically with a 2:1 margin. The rod ends in a female M6x1.0 thread and the air port is M5x0.8. This model is discontinued; the current-production replacement is the ASE20X5, so confirm the ISO 21287 mounting dimensions before swapping. Note there is no magnet fitted - the optional -S code is required if you later want CMSE or DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE20X5 (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 (spring return) |
|---|---|
| 0.5 MPa | 127.4 N |
| 0.7 MPa | 190.2 N |
Single-acting push: air extends the rod; the return spring retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

Where the Airtac ASP Single Acting Guided Compact Cylinder ASP20X5 Is Used
PCB test fixture clamping
The 127.4 N push at 0.5 MPa is enough to press small circuit boards onto test pogo-pin beds, and the 5 mm stroke keeps the clamp head travel tight and fast.
Micro part ejection from a mold or nest
A quick 5 mm kick at up to 500 mm/s nudges tiny stamped or molded parts out of shallow nests on an automated assembly line, with the spring retracting the pin between cycles.
Presence check on a packaging line
With the optional -S magnet and a CMSE switch, the short stroke can confirm a carton or tray is seated in a fixture before the next machine cycle starts.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP20X5 with the ASE20X5
At 127.4 N push at 0.5 MPa, the 20 mm bore sits between the 16 mm (78.4 N) and 25 mm (210.1 N) sizes - step down for lighter eject or index tasks, up if your load needs more margin. Because the spring returns the rod on air loss, this cylinder cannot hold a mid-stroke position; it always parks retracted. Mounting brackets from the FA/FB flange, LB foot and CA/CB clevis family bolt to the standard face, and the optional -S magnet enables CMSE / DMSE sensing. Order the ASE20X5 as the current drop-in replacement.
Replacement checklist
- ✓ Current-production ACE → ASE20X5
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ASP Single Acting Guided Compact Cylinder ASP20X5 FAQ
It is a single acting push, spring-return cylinder: 127.4 N push at 0.5 MPa and 190.2 N at 0.7 MPa, both already net of the return spring. Bore 20 mm, stroke 5 mm, rod 10 mm with a female M6x1.0 thread, M5x0.8 port, operating pressure 0.2-1.0 MPa (28-145 psi), proof 1.5 MPa (215 psi), speed 50-500 mm/s, temperature -20 to +70 C, air filtered to 40 um. The model is discontinued; the ASE20X5 is the current replacement.
The body is hard-anodized aluminium with an S45C hard-chrome rod and fixed TPU bumpers at both ends, in a compact format roughly 50% shorter in mounting length than an ISO 15552 profile cylinder. Sensing is not included by default: you must order the optional -S code to get the magnet, which then accepts CMSE or DMSE switches. Without -S there is no magnet and no switching is possible.
