About the Airtac ATE Single Acting Guided Compact Cylinder ATE32X25
This ATE32X25 is a genuine AirTAC ISO 21287 compact cylinder built for single acting pull duty, where the spring extends the rod and air retracts it. With a 32 mm bore, it delivers a net pull of 296 N at 0.5 MPa and 434.2 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa needed to overcome the spring. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight machine guarding and compact jigs where space is at a premium.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling, while the fixed TPU bumper at both ends absorbs end-of-stroke impact. For a safe working margin, plan for roughly 178 N of real work at 0.5 MPa, which translates to lifting about 18 kg vertically with a 2:1 safety factor. The 1/8" port and M8x1.25 female rod thread are standard for this bore size, and the optional -S magnet can be ordered to enable CMSE or DMSE sensor mounting.

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 ATE32X25 Is Used
Jig Clamping Retract
Use the 296 N pull at 0.5 MPa to retract a locating pin in a CNC fixture, where the spring extends the pin to engage the workpiece and air pulls it clear for unloading.
Conveyor Stop Release
Mount this 32 mm bore cylinder on a packaging line to pull a stop gate down and let cartons pass, with the spring returning the gate to block position when air is removed.
Guard Door Latch
In a machine safety circuit, the ATE32X25 pulls a latch bolt to unlock an access door, and the spring extends the bolt to secure the guard when the air supply is off.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE32X25 the Right Cylinder?
When sizing this ATE32X25, compare it against the smaller ATE25X25 which pulls 170.9 N at 0.5 MPa, or step up to the ATE40X25 for 500.3 N at the same pressure. The 25 mm stroke is the maximum standard for this bore, so if you need longer travel, you will require a non-standard made-to-order stroke. Remember that on air loss, the spring returns the rod to its extended home position and does not hold a mid-stroke load. Choose the -S code if you need the optional magnet for CMSE or DMSE sensors, and select from FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC mounting brackets to match your fixture.
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 ATE32X25 FAQ
The ATE32X25 provides a net pull force of 296 N at 0.5 MPa and 434.2 N at 0.7 MPa, with the spring force already subtracted. The minimum working pressure is 0.2 MPa, operating range is 0.2-1.0 MPa (28-145 psi), and proof pressure is 1.5 MPa (215 psi). Speed range is 50-500 mm/s.
The ISO 21287 compact body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits into tight spaces like machine guards and gantries. The fixed TPU bumper at both ends absorbs end-of-stroke energy. The optional -S magnet enables CMSE or DMSE sensor mounting, and FA/FB, LB, CA/CB, CR, SDB, and FTC mounting options are available.
