This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE25X15S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE25X15S 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 ASP25X15S
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP25X15S is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø25mm 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 ASE25X15S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP25X15S
The ASP25X15S is a single acting push cylinder with spring return: air extends the rod and the internal spring retracts it, so only one air line is needed. This 25 mm bore unit delivers 210.1 N of push at 0.5 MPa (net of the spring) and 308.3 N at 0.7 MPa, with a 15 mm stroke and a 10 mm rod ending in a female M6x1.0 thread. It runs on 0.2-1.0 MPa (28-145 psi) of filtered air at 50-500 mm/s. Note that the ASP family is discontinued; the current-production replacement is the ASE25X15.
Its 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 jigs and guarding where a full-length body will not fit. The hard-anodized aluminium body carries a fixed TPU bumper at both ends, and because this model carries the optional -S magnet, CMSE or DMSE reed and solid-state switches can be mounted directly on the tube. For sizing, treat about 126 N (roughly 60% of the 0.5 MPa rating) as the practical working force, which lifts about 10 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE25X15S (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 (Ø25mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 210.1 N |
| 0.7 MPa | 308.3 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 ASP25X15S Is Used
Small-part press fitting
Seating dowel pins or bearings into aluminium housings on an electronics assembly bench, where the 210.1 N push at 0.5 MPa and 15 mm travel match light press work.
Spring-return clamp on a drill jig
Holding thin sheet-metal brackets against a drill jig: air loss automatically retracts the clamp, freeing the part without a trapped-pressure valve.
Position-checked ejector
Kicking small finished parts off a conveyor stop with confirmation of extension via a CMSE or DMSE switch, since this model carries the -S magnet.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP25X15S with the ASE25X15S
Size by force first: at 0.5 MPa this bore pushes 210.1 N net of the spring, so a 20 mm bore (127.4 N) suits lighter clamps and a 32 mm bore (352.5 N) suits heavier ones. Remember the spring drives the rod home on air loss, so the cylinder returns to retracted rather than holding a mid-stroke position. The 15 mm stroke sits well inside the standard range for this bore, and the female M6x1.0 rod thread accepts I/Y knuckles directly. If you need position sensing, this S-coded model already carries the magnet for CMSE / DMSE switches. For new builds, order the ASE25X15 instead - it is the current drop-in, but confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ASE25X15S
- ✓ 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 ASP25X15S FAQ
Push force is 210.1 N at 0.5 MPa and 308.3 N at 0.7 MPa, both already net of the return spring. Bore is 25 mm, stroke 15 mm, rod 10 mm with a female M6x1.0 thread, port M5x0.8. Operating pressure is 0.2-1.0 MPa (28-145 psi), proof 1.5 MPa (215 psi), temperature -20 to +70 C, speed 50-500 mm/s, air filtered to 40 um. The model is discontinued; the ASE25X15 is the current replacement.
The compact short-body construction saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow pockets, guards and gantries. This S-coded unit carries the optional -S magnet, letting you bolt CMSE or DMSE reed or solid-state switches onto the tube for end-of-stroke signals. A fixed TPU bumper decelerates the rod at each end, and FA/FB flange or LB foot mounts bolt to standard fixture faces.
