This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ASE50X25, the same code under the new prefix. 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 ASP50X25
The AirTAC ASP Single Acting Guided Compact Cylinder ASP50X25 is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø50mm bore and 25mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE50X25 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP50X25
A single acting push cylinder with spring return, the ASP50X25 uses shop air to extend its 16 mm rod and an internal spring to retract it, so one air line is all the plumbing needs. At 0.5 MPa it delivers 875.5 N of push force net of the spring (1268.2 N at 0.7 MPa), and it needs at least 0.2 MPa to overcome the spring. The 50 mm bore sits in the mid-force class of the range, well above the 352.5 N of a bore 32 unit. Note that this model is discontinued; the current-production replacement is the ASE50X25 (swap the P for an E), 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 tight welding jigs and packaging frames where a full-length body will not reach. A fixed TPU bumper pads both ends of travel, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the optional -S magnet code enables CMSE / DMSE switches (no magnet is fitted without it). Speed range is 50-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE50X25 (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 (Ø50mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 875.5 N |
| 0.7 MPa | 1268.2 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 ASP50X25 Is Used
Packaging carton press
The 875.5 N push at 0.5 MPa seats flaps and labels on a carton sealing line, and the spring retracts the platen the moment air is removed.
Fixture part ejector
Mounted on an LB foot inside a machining fixture, the 25 mm stroke kicks finished bushings off a locating pin between cycles at 50-500 mm/s.
Gate latch actuator
On a conveyor gate, the single air line pushes the latch pin home while the return spring pulls it back on power loss, fail-safe to the retracted state.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP50X25 with the ASE50X25
Size by force: if 875.5 N at 0.5 MPa is more than your jig needs, the bore 40 ASP40X25 gives 556.8 N; if you need more, the bore 63 ASP63X25 reaches 1420.5 N. Remember the spring drives the rod home on air loss, so this cylinder will not hold a mid-stroke position under load. Mounting brackets FA/FB flange, LB foot and CA/CB clevis bolt to the standard face, and the female M10x1.5 rod thread accepts standard knuckles. Order the -S code if you want the magnet for CMSE / DMSE position switches. Before ordering, confirm the ISO 21287 mounting dimensions of the ASE50X25 replacement, since this DIN-standard body is no longer produced.
Replacement checklist
- ✓ Current-production ACE → ASE50X25
- ✓ 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 ASP50X25 FAQ
Push force is 875.5 N at 0.5 MPa and 1268.2 N at 0.7 MPa, both already net of the return spring. Working pressure is 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa (215 psi), minimum 0.2 MPa to beat the spring. Fluid is air filtered to 40 um, temperature range -20 to +70 C, speed 50-500 mm/s. Bore 50 mm, stroke 25 mm, rod 16 mm, port 1/8", female rod thread M10x1.5.
Order the ASE50X25, the current-production ISO 21287 successor (swap the P for an E). It matches the same 50 mm bore, 25 mm stroke and force class, and the FA/FB, LB and CA/CB mounting family carries over, but confirm the ISO 21287 mounting dimensions before swapping because this DIN-standard body is no longer manufactured.
