Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X25S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X25S is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø32mm bore and 25mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X25S
This AirTAC ASE32X25S is a single acting push cylinder with spring return, so air extends the rod and the built-in spring retracts it, needing only one air line. It delivers 352.5 N of push force at 0.5 MPa (net of the spring) and 513.4 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa to overcome the spring.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight jigs and guards where a full-length cylinder will not. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing, and the fixed TPU bumper at both ends absorbs end-of-stroke energy. For a safe working load, plan for about 211 N (or roughly 22 kg) of real work at 0.5 MPa, not the full 352.5 N rating.

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. Single-acting strokes are short (Ø12 to 10 mm, Ø16-100 to 25 mm).

Where the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X25S Is Used
Fixture Clamping
Use in a CNC fixture to clamp small parts with 352.5 N at 0.5 MPa, where the compact body fits under a workholding plate and the spring retracts the clamp when air is released.
Conveyor Stop
Mount on a packaging line to stop lightweight cartons at a 25 mm stroke, with the spring returning the stop pin so products flow freely when the air signal drops.
Guard Door Interlock
Activate a safety interlock on a machine guard, where the 32 mm bore pushes a latch into place and the spring pulls it back, fitting in the narrow gap between guard and frame.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X25S the Right Cylinder?
For lighter duty, the 25 mm bore ASE25X25 offers 210.1 N at 0.5 MPa, while stepping up to the 40 mm bore ASE40X25 gives 556.8 N at 0.5 MPa if you need more force. Since this is single acting, the spring returns the rod to its home position on air loss, but it does not hold a mid-stroke position, so use it for simple extend-and-retract tasks. With the -S magnet, you can mount CMSE or DMSE switches, and the ISO 21287 face accepts FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC brackets for versatile installation.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Single-acting: do not force the rod against the spring.
- check Installation by qualified personnel per AirTAC docs.
Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X25S FAQ
The push force is 352.5 N at 0.5 MPa and 513.4 N at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, proof pressure is 1.5 MPa (215 psi), and operating pressure range is 0.2-1.0 MPa (28-145 psi). Speed range is 50-500 mm/s.
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight jigs and guards. The fixed TPU bumper absorbs end-of-stroke impact, and the optional -S magnet (fitted here) allows CMSE or DMSE switches for sensing. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets.
