This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE20X15S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE20X15S 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 ASP20X15S
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP20X15S is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø20mm bore and 15mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE20X15S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP20X15S
A single acting push cylinder with spring return, the discontinued ASP20X15S uses air to extend the rod and an internal spring to retract it, so one air line is all the plumbing a 20 mm bore station needs. 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; the spring only wins below 0.2 MPa, the minimum working pressure. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight fixture plates and guarding where a full-length body will not fit.
Because the S code is in this model, the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling without any extra ordering step. A fixed TPU bumper at each end decelerates the rod, and the hard-anodized aluminium body with an S45C hard-chrome rod stands up to daily cycling. Plan on about 76 N of real work at 0.5 MPa (roughly 60% of the rating), which corresponds to lifting about 6 kg vertically with a 2:1 margin. This model is discontinued: the current-production replacement is the ASE20X15, and buyers should confirm the ISO 21287 mounting dimensions before swapping, since the ASP follows a DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE20X15S (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 ASP20X15S Is Used
Small-part press fitting
The 127.4 N push at 0.5 MPa seats dowel pins or nylon standoffs into plastic housings on an electronics assembly bench, with the spring clearing the ram between cycles.
Position-confirmed ejector
With the fitted -S magnet driving a DMSE switch, a PCB transfer gantry confirms the 15 mm eject stroke is complete before the conveyor indexes the next board.
Blister tray hold-down
A cartoning machine uses the short body to hold blister trays under a sealing head, retreating automatically to the retracted home position whenever air pressure drops.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP20X15S with the ASE20X15S
Size this bore by load: the 16 mm bore gives 78.4 N at 0.5 MPa, while stepping up to 25 mm raises it to 210.1 N, so pick 20 mm when your clamping or ejecting job sits between those figures. Remember the spring returns the rod home on air loss and will not hold a mid-stroke position, so add an external stop if the workpiece must stay put. The female M6x1.0 rod thread takes standard I/Y knuckles, and the 15 mm stroke sits inside the standard range for this bore. Order the ASE20X15 as the drop-in successor and verify the ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ASE20X15S
- ✓ 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 ASP20X15S FAQ
Push force is 127.4 N at 0.5 MPa and 190.2 N at 0.7 MPa, both already net of the return spring. Operating pressure is 0.2-1.0 MPa (28-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed range 50-500 mm/s, temperature -20 to +70 C, and air filtered to 40 um. The port is M5x0.8 and the rod end carries a female M6x1.0 thread.
The S in this model code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted for stroke signalling; models without the S code carry no magnet. The ASP20X15S itself is discontinued, and the current-production drop-in is the ASE20X15 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.
