Airtac ATE Single Acting Guided Compact Cylinder ATE25X15B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE25X15B is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø25mm bore and 15mm stroke, M5×0.8 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 ATE25X15B
This AirTAC ATE25X25B is a single acting pull cylinder, with a spring that extends the rod and air that retracts it. The 25 mm bore delivers a net pull of 170.9 N at 0.5 MPa, a force well-suited for light clamping and indexing tasks.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, freeing space in tight fixtures. With a male rod thread and M5x0.8 port, it mounts directly to standard brackets. At 0.5 MPa, a safe working load is about 103 N, or roughly 10 kg, giving a clear margin for real applications.

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 (Ø25mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 170.9 N |
| 0.7 MPa | 253.3 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 ATE25X15B Is Used
Fixture Clamping
Use the 170.9 N pull at 0.5 MPa to retract a clamp arm on a small CNC fixture, holding parts during drilling.
Gate Release
In a parts bin, this cylinder pulls a gate pin to release small components onto a chute, with the spring extending it for the next cycle.
Jig Positioning
Mount it on a manual assembly jig to pull a locating pin out of a hole, allowing the operator to rotate the part.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE25X15B the Right Cylinder?
For a smaller option, the 20 mm bore offers 88.1 N pull at 0.5 MPa, while the 32 mm bore provides 296.0 N for heavier work. This 25 mm bore is a balanced middle ground for light automation. Note that on air loss, the spring returns the rod to its extended position, so it cannot hold a mid-stroke load. Choose the optional -S code for a magnet to enable CMSE or DMSE sensors.
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 ATE25X15B FAQ
The net pull force is 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa. The proof pressure is 1.5 MPa (215 psi) and the operating range is 0.2-1.0 MPa (28-145 psi).
This model has no magnet, so no sensor can be mounted. To use CMSE or DMSE switches, you must order the ATE25X15B-S variant, which includes the optional magnet. The fixed TPU bumper at both ends absorbs energy at the end of stroke.
