This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ASE100X25, 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 ASP100X25
The AirTAC ASP Single Acting Guided Compact Cylinder ASP100X25 is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø100mm bore and 25mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE100X25 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP100X25
The ASP100X25 is a single acting push cylinder with spring return: air extends the 25 mm rod and the internal spring retracts it, so one air line is enough. At 0.5 MPa the push force is 3640.7 N net of the spring, rising to 5211.5 N at 0.7 MPa, and the 100 mm bore needs at least 0.2 MPa to overcome the spring. This model is discontinued; the current-production replacement is ASE100X25, the ISO 21287 successor in the same bore, stroke and force class.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in heavy clamping fixtures and press gantries where every millimetre counts. A fixed TPU bumper sits at both ends, and the optional -S magnet code enables CMSE / DMSE switches; without -S there is no magnet.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE100X25 (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 (Ø100mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 3640.7 N |
| 0.7 MPa | 5211.5 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 ASP100X25 Is Used
Press-frame clamping
The 3640.7 N push at 0.5 MPa clamps steel housings in a 25 mm stroke welding press, with the spring clearing the part the moment air drops.
Machining-centre part ejector
Mounted through a fixture plate, the short ISO 21287 body kicks finished castings off a CNC jig in one 25 mm stroke and retracts on spring return.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP100X25 with the ASE100X25
At this force class, 3640.7 N at 0.5 MPa covers heavy clamps and short-stroke presses; if the job needs less, the 80 mm bore gives 2316.2 N at the same pressure. Remember the spring returns the rod home on air loss, so it will not hold a mid-stroke position. Match FA/FB flange, LB foot or CA/CB clevis mounts to your fixture, and order the -S code only if CMSE / DMSE sensing is required. For new projects, specify ASE100X25 and confirm the ISO 21287 mounting dimensions before swapping, since the ASP is DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ASE100X25
- ✓ 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 ASP100X25 FAQ
Push force is 3640.7 N at 0.5 MPa and 5211.5 N at 0.7 MPa, both already net of the return spring, so no derating is needed. Working pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, speed 50-500 mm/s, and the 1/4" port feeds the 100 mm bore. At 0.2 MPa the air just starts to beat the spring.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot and CA/CB clevis options on the 25 mm female-threaded rod (M16x1.5). Sensing is not fitted as standard: add the optional -S magnet code to enable CMSE / DMSE switches. This model is discontinued, so order ASE100X25 as the current direct and confirm ISO 21287 mounting dimensions first.
