This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE25X15SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE25X15SB 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 ASP25X15SB
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP25X15SB 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 ASE25X15SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP25X15SB
A single acting push cylinder with spring return, the discontinued ASP25X15SB uses shop air to extend its 10 mm rod and an internal spring to pull it home - only one air line is needed, and 0.2 MPa is the minimum working pressure to beat the spring. At 0.5 MPa it delivers 210.1 N of push net of the spring (308.3 N at 0.7 MPa), so plan on roughly 126 N of real work once you keep a margin. The short ISO 21287-class body saves about 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 cannot.
This 25 mm unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signals; models ordered without -S have no magnet at all. The male rod thread (B code) bolts to I/Y knuckles, and the fixed TPU bumper at each end simply decelerates the rod. Note the ASP family is discontinued: the current-production drop-in is the ASE25X15, which matches this bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ASP was built to a DIN-standard footprint.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE25X15SB (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 ASP25X15SB Is Used
Small bracket press-fit
The 210.1 N push at 0.5 MPa seats light aluminium brackets into a locating nest on an electronics assembly bench, with the spring clearing the part the moment air is released.
Part-present ejection
With the -S magnet and a DMSE switch, the 15 mm stroke confirms a plastic cap has cleared a packaging chute before the next cycle starts.
Fixture lid latch
A CNC jig uses the male-thread rod and a clevis to swing a small clamp lid closed; the short body fits under the guard where a longer cylinder would not.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP25X15SB with the ASE25X15SB
Size by force first: if 210.1 N at 0.5 MPa is marginal for your clamp or eject load, step up to the 32 mm bore (352.5 N at 0.5 MPa); if it is far more than needed, the 20 mm bore (127.4 N) saves air and space. Vertically, this cylinder lifts about 10 kg with a 2:1 margin (21 kgf raw at 0.5 MPa). Remember the spring drives the rod fully home on air loss - it will not hold a mid-stroke position. Choose FA/FB flange, LB foot or CA/CB clevis to match the fixture, keep the -S magnet if you need CMSE/DMSE switching, and order the ASE25X15 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ASE25X15SB
- ✓ 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 ASP25X15SB FAQ
Net of the return spring it pushes 210.1 N at 0.5 MPa and 308.3 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, speed 50-500 mm/s, temperature -20 to +70 C, on air filtered to 40 um. The port is M5x0.8, the rod is 10 mm with a male thread, and the 15 mm stroke sits within the standard range for this bore.
Order the ASE25X15, the current-production ISO 21287 successor: swap the P for an E and you get the same 25 mm bore, 15 mm stroke and force class in a matching short body. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, because the ASP followed a DIN-standard footprint, and re-order the -S magnet code if your CMSE or DMSE switches must keep working.
