This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE25X10B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE25X10B 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 ASP25X10B
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP25X10B 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 ASE25X10B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP25X10B
A single acting push cylinder with spring return, the AirTAC ASP25X10B uses shop air to extend its rod and an internal spring to retract it, so only one air line is needed. At the 25 mm bore it delivers 210.1 N of push at 0.5 MPa and 308.3 N at 0.7 MPa, both figures already net of the return spring. It needs at least 0.2 MPa to overcome the spring, runs on air filtered to 40 um, and strokes at 50-500 mm/s. This exact model is discontinued; the current-production replacement is the ASE25X10, which keeps the same bore, stroke and force class.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped jigs and guarding where a full-length body cannot. For sizing, treat about 126 N (0.6 of the 0.5 MPa rating) as the usable working force, which corresponds to lifting roughly 10 kg vertically with a 2:1 margin. The rod end is male thread (the B code) and the air port is M5x0.8. No magnet is fitted on this code; order the optional -S version if you need CMSE or DMSE switch sensing.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE25X10B (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 ASP25X10B Is Used
Bottle-capping press head
The 10 mm stroke seats a cap onto 30 ml cosmetic bottles on a small packaging line; the 210.1 N push at 0.5 MPa is enough for snap-on caps, and the spring retracts the head the moment air drops.
Part-present kick-off gate
Mounted beside a conveyor lane, the male-thread rod nudges misaligned brackets off the belt; at 0.7 MPa the 308.3 N net push clears steel parts, and the short body fits under the guard rail.
Fixture clamp for PCB test rigs
Clamps a circuit-board carrier into a test nest with about 126 N of practical working force, lifting roughly 10 kg equivalent vertically; the compact footprint fits inside the jig frame.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP25X10B with the ASE25X10B
Pick the ASP25X10B when a 10 mm approach stroke and about 210 N of net push at 0.5 MPa cover the job, and you want spring retraction on air loss rather than a second air line. If the load needs more muscle, step up to the 32 mm bore (352.5 N at 0.5 MPa); if less force is fine, the 20 mm bore gives 127.4 N. Remember the spring drives the rod fully home when air is lost - it will not hold a mid-stroke position. Mounting brackets (FA/FB flange, LB foot, CA/CB clevis) and the optional -S magnet for CMSE / DMSE switches should be chosen at order time. Since this model is discontinued, specify the ASE25X10 and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ASE25X10B
- ✓ 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 ASP25X10B FAQ
It is a single acting push, spring-return cylinder: air extends the rod, the spring retracts it. Net push (already minus the spring) is 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 0.2 MPa as the minimum to beat the spring; proof pressure is 1.5 MPa (215 psi). Speed range is 50-500 mm/s and the fluid is air filtered to 40 um.
Only if you order the -S code: that optional magnet lets CMSE or DMSE reed or solid-state switches sense end positions. This ASP25X10B (no S) carries no magnet, so no switch can be mounted. The model is discontinued; the current-production drop-in is the ASE25X10 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before converting.
