Airtac ATE Single Acting Guided Compact Cylinder ATE32X25B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE32X25B is a genuine single acting, pull (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 ATE Single Acting Guided Compact Cylinder ATE32X25B
This AirTAC ATE32X25B is a single acting pull cylinder, with a spring that extends the rod and air that retracts it. At 0.5 MPa it delivers a net pull of 296 N, and at 0.7 MPa that rises to 434.2 N, so it suits light clamping and indexing tasks.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, making it ideal for tight jigs and guards. The male rod thread (B code) allows direct coupling to linkages, and the hard-anodized aluminium body with S45C chrome rod resists wear. At 0.5 MPa, a safe working load is about 18 kg (0.6 x 296 N divided by 9.81), so plan for real work around that figure.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø32mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 296.0 N |
| 0.7 MPa | 434.2 N |
Single-acting pull: the spring extends the rod; air 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 ATE Single Acting Guided Compact Cylinder ATE32X25B Is Used
Jig Clamping
Use the 296 N pull at 0.5 MPa to retract a clamp pin in a small assembly jig, freeing operators' hands for part placement. The compact body fits under a workbench guard where a longer cylinder would not.
Indexing Stop
Mount this cylinder to pull a locating stop out of a conveyor path on a packaging line. With a 25 mm stroke, it clears the stop quickly, and the spring returns it to block the next part when air is released.
Small Press Guard
In a bench-top press, this unit retracts a safety shield or guard panel before the ram cycles. The 434.2 N pull at 0.7 MPa moves the guard reliably, and the fixed TPU bumper absorbs end-of-stroke impact.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE32X25B the Right Cylinder?
For a smaller pull force, consider the ATE25X25 with 170.9 N at 0.5 MPa, or step up to the ATE40X25 for 500.3 N. This 32 mm bore is a middle ground for compact automation where space is tight but force is still needed. The spring returns the rod to its extended position on air loss, so it does not hold a mid-stroke load. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all fitting the ISO 21287 face. The optional -S magnet is not fitted here, so CMSE or DMSE sensors cannot be used unless you order the -S code.
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 ATE Single Acting Guided Compact Cylinder ATE32X25B FAQ
At 0.5 MPa, the net pull is 296 N, and at 0.7 MPa it is 434.2 N, both after accounting for the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi). The port is 1/8" PT, and the rod is 12 mm with a male thread.
The ATE32X25B uses an ISO 21287 compact design, which is about 50% shorter than an ISO 15552 profile cylinder. This lets you fit it into tight jigs, guards, or gantries where a full-length cylinder would not. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the optional -S magnet is not included here, so order the -S code if you need CMSE or DMSE sensors.
