This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE20X5S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE20X5S 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 ASP20X5S
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP20X5S 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 ASE20X5S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP20X5S
The ASP20X5S is a single acting push cylinder with spring return: air extends the 10 mm rod and the internal spring retracts it, so the unit sits normally retracted and needs only one air line. With a 20 mm bore it delivers 127.4 N of push at 0.5 MPa (190.2 N at 0.7 MPa), both figures already net of the return spring, and it starts moving from just 0.2 MPa. The S in the code means the optional magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the body for end-of-stroke detection.
This is a DIN-standard compact body in hard-anodized aluminium with an S45C hard-chrome rod and a fixed TPU bumper at each end, and its short build saves about 50% of the mounting length of an ISO 15552 profile cylinder. For sizing, treat roughly 76 N (0.6 of the 127.4 N rating) as the practical working force at 0.5 MPa, which corresponds to lifting about 6 kg vertically with a 2:1 margin. Note that this model is discontinued: the current-production replacement is the ASE20X5 (swap the P for an E), so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE20X5S (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 ASP20X5S Is Used
Bracket clinching on electronics assembly benches
A 5 mm stroke and 127.4 N at 0.5 MPa are enough to press small clips and terminals into plastic housings, with the spring returning the tool instantly when air is removed.
Position confirm on semiconductor jigs
The fitted -S magnet accepts CMSE or DMSE switches, so a fixture can confirm the 5 mm clamp is made before the next step starts.
Carton flap tuck on small packaging machines
The short compact body fits inside tight guarding where a full-length ISO 15552 profile cylinder will not, and the single air line keeps plumbing simple.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP20X5S with the ASE20X5S
At 127.4 N push at 0.5 MPa, the 20 mm bore sits between the 16 mm bore (78.4 N) and the 25 mm bore (210.1 N); step up to 25 mm if your jig needs more margin, or down to 16 mm to save space. Because the spring drives the rod home on air loss, this cylinder returns to the retracted position rather than holding a mid-stroke load. The 5 mm stroke is a standard short stroke for this bore, the rod end is female M6x1.0 and the port is M5x0.8 PT, and FA/FB flange, LB foot or CA/CB clevis mounting can be ordered. This model is discontinued, so order the ASE20X5 as the current drop-in and verify the ISO 21287 footprint first.
Replacement checklist
- ✓ Current-production ACE → ASE20X5S
- ✓ 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 ASP20X5S FAQ
Push is 127.4 N at 0.5 MPa and 190.2 N at 0.7 MPa, both already net of the return spring. A practical rule is to plan for about 76 N of real work at 0.5 MPa, which lifts roughly 6 kg vertically with a 2:1 margin. Minimum working pressure is 0.2 MPa (28-145 psi overall range, proof 1.5 MPa / 215 psi), speed is 50-500 mm/s, the port is M5x0.8 and the rod thread is female M6x1.0.
No, the ASP20X5S is discontinued. The current-production replacement is the ASE20X5, an ISO 21287 compact cylinder in the same bore, stroke and force class. Because the ASP was built to a DIN-standard compact format, confirm the ISO 21287 mounting dimensions against your fixture before swapping, and remember the magnet on this unit was the optional -S code, so order the magnet variant of the ASE if you run CMSE or DMSE switches.
