About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X25SB
This AirTAC ASE32X25SB is a single acting push cylinder with spring return, built to ISO 21287 compact dimensions. It delivers 352.5 N of push force at 0.5 MPa (net of the return spring) and 513.4 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight machine frames and guarding. For a safe working load, plan for roughly 212 N of real work at 0.5 MPa, which equals lifting about 21.6 kg vertically with a 2:1 safety margin.
The body is hard-anodized aluminium alloy with a roller-burnished bore, and the S45C steel rod is hard-chrome plated. This model includes the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for position sensing. A fixed TPU bumper at both ends absorbs end-of-stroke energy, and the port is 1/8" PT. The rod has a male thread (B code), and the unit operates on filtered air (40 um) at 0.2-1.0 MPa (28-145 psi).

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 ASE32X25SB Is Used
Jig Clamping
Use in a CNC fixture to clamp small parts with 352.5 N force at 0.5 MPa, ensuring a firm hold during drilling or milling operations.
Parts Ejection
Mount on a packaging line to push finished components off a conveyor into a chute, with the spring return resetting the rod for the next cycle.
Guard Interlock
In a machine safety gate, this cylinder can extend a locking pin into a guard frame, providing a positive stop with a compact footprint.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X25SB the Right Cylinder?
For a lighter duty, the ASE25X25 offers 210.1 N at 0.5 MPa, while the ASE40X25 provides 556.8 N at the same pressure, so you can scale up or down based on your force needs. This 32 mm bore with a 25 mm stroke is a compact choice for short, repetitive pushes. Remember, the spring retracts the rod on air loss, so it does not hold a mid-stroke position. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with the ISO 21287 face. The optional -S magnet is fitted here, enabling sensor feedback for automation control.
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 ASE32X25SB FAQ
At 0.5 MPa, the push force is 352.5 N, and at 0.7 MPa it is 513.4 N, both net of the return spring. The minimum working pressure is 0.2 MPa, and the maximum is 1.0 MPa (145 psi).
The short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, fitting into tight spaces. It also has a fixed TPU bumper at both ends for quiet operation, and the optional -S magnet allows CMSE or DMSE sensors to detect rod position.
