This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE25X10SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE25X10SB 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 ASP25X10SB
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP25X10SB is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø25mm bore and 10mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE25X10SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP25X10SB
A single acting push cylinder with spring return, the ASP25X10SB uses shop air to extend the rod and an internal spring to pull it back home, so only one air line is needed. At 0.5 MPa the 25 mm bore delivers 210.1 N of push already net of the spring (308.3 N at 0.7 MPa), and 0.2 MPa is the minimum pressure needed to beat the spring. The male rod thread (B code) and the fitted -S magnet for CMSE / DMSE switches make it easy to wire position feedback into a compact fixture.
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, guarding and gantries. In practice, plan on roughly 126 N of real work at 0.5 MPa (about 60% of the rating), which lifts around 6 kg vertically - halve that for a 2:1 margin and match it to your part weight. Note this model is discontinued: the current-production replacement is the ASE25X10, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE25X10SB (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 ASP25X10SB Is Used
Bench-top press jig
The 210.1 N push at 0.5 MPa is enough to seat small dowels or snap-fit caps in an electronics assembly jig, with the 10 mm stroke matching a short press travel.
Presence-check gate on a packaging line
With the -S magnet fitted, CMSE or DMSE switches confirm the rod is extended before the carton erector releases the next blank.
Ejector in a small injection fixture
Spring return guarantees the eject pin retracts the moment air is lost, clearing the mould area without a second valve port.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP25X10SB with the ASE25X10SB
Size the bore against your load: at 0.5 MPa the smaller 20 mm bore pushes 127.4 N while the 32 mm bore reaches 352.5 N, so the 25 mm at 210.1 N sits squarely between them for light clamping and eject duties. Remember the spring drives the rod fully home on air loss - it will not hold a mid-stroke position. If you need a flange, foot or clevis, the FA/FB, LB and CA/CB brackets bolt straight to the face; order the ASE25X10 as the current drop-in successor.
Replacement checklist
- ✓ Current-production ACE → ASE25X10SB
- ✓ 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 ASP25X10SB 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. It is a single acting push cylinder with a 25 mm bore, 10 mm stroke, 10 mm rod, M5x0.8 port, male rod thread, operating range 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa (215 psi), speed 50-500 mm/s, temperature -20 to +70 C, and air filtered to 40 um.
The hard-anodized aluminium body follows the short ISO 21287-class format, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it fits where a full-length cylinder will not. Fixed TPU bumpers at both ends decelerate the rod at each end of travel; they are not adjustable and never lock or hold a load. This model is discontinued - the ASE25X10 is the current replacement, so confirm ISO 21287 mounting dimensions before ordering.
