This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ASE32X25SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ASE32X25SB 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 ASP32X25SB
The AirTAC Airtac ASP Single Acting Guided Compact Cylinder ASP32X25SB is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø32mm bore and 25mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE32X25SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP32X25SB
Single acting push cylinder with spring return: air extends the rod and the return spring retracts it, so the ASP32X25SB needs only one air line and sits normally retracted at rest. This 32 mm bore, 25 mm stroke unit delivers 352.5 N of push at 0.5 MPa and 513.4 N at 0.7 MPa, both already net of the spring, and it takes just 0.2 MPa (28-145 psi working band) to beat the spring and start the stroke. The S code in the model means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped straight onto the body for end-of-stroke signalling.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it drops into tight jigs, guarding and gantries where a full-length body will not fit. The B code gives a male rod thread on the 12 mm rod, and a fixed TPU bumper at each end decelerates the stroke. In practical terms, plan on about 211 N of usable push at 0.5 MPa, which lifts roughly 18 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production replacement is the ASE32X25, and you should confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE32X25SB (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 (Ø32mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 352.5 N |
| 0.7 MPa | 513.4 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 ASP32X25SB Is Used
Bench press ejection
Kicks finished aluminium brackets off a small assembly press; the 352.5 N push at 0.5 MPa is enough for light eject work and the spring return clears the die the moment air is lost.
Carton hold-down on a packing line
Presses folded flaps on 25 mm-tall carton stacks at up to 500 mm/s; the short body fits under low guarding where a full-length profile cylinder cannot.
Gantry part present check
With the fitted -S magnet and a DMSE switch, the PLC confirms rod extension on each cycle of a vision-inspection gantry; spring retraction gives a fail-safe home position.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP32X25SB with the ASE32X25SB
Size both ways before committing: the 25 mm bore pushes 210.1 N at 0.5 MPa if your load is lighter, while the 40 mm bore gives 556.8 N if you need more headroom, both net of their return springs. Because the spring drives the rod home on air loss, this cylinder retracts to its home position but does not hold an arbitrary mid-stroke position, so add a separate stop or clamp if you need to park a load mid-travel. The male rod thread (B code) pairs with I/Y rod knuckles, and FA/FB flange, LB foot or CA/CB clevis mountings bolt to the same face; the fitted -S magnet accepts CMSE/DMSE switches. Order the ASE32X25 as the current drop-in replacement for this discontinued model.
Replacement checklist
- ✓ Current-production ACE → ASE32X25SB
- ✓ 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 ASP32X25SB FAQ
Push force is 352.5 N at 0.5 MPa and 513.4 N at 0.7 MPa, both already net of the return spring, so no further deduction is needed. It is a single acting push cylinder: air extends the rod, the spring retracts it, and the minimum working pressure is 0.2 MPa. Operating range is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof pressure, running on air filtered to 40 um at 50-500 mm/s.
Yes, the ASP family is out of production; order the ASE32X25, which swaps the P for an E and matches the same 32 mm bore, 25 mm stroke and force class as a current-production drop-in. Confirm the ISO 21287 mounting dimensions before swapping since this unit is DIN-standard. For feedback, this ASP32X25SB carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches mount directly on the body; the fixed TPU bumpers at both ends simply decelerate the stroke.
