Airtac ATE Single Acting Guided Compact Cylinder ATE25X5B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE25X5B is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø25mm bore and 5mm 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 ATE25X5B
This AirTAC ATE25X5B is a single acting pull cylinder with spring return, so the spring extends the rod and air retracts it. With a 25 mm bore, it delivers a net pull of 170.9 N at 0.5 MPa, making it ideal for light clamping or lifting tasks where a compact footprint matters.
Its ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight jigs and guards. The optional -S magnet is not fitted here, so no sensor can be mounted without ordering that code. For real work, plan for about 103 N (0.6 times the 0.5 MPa rating) to maintain a safety margin, which lifts roughly 10.5 kg vertically with a 2:1 safety factor.

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 ATE25X5B Is Used
Jig Clamping
Use in a drill jig to pull a clamp arm down onto a workpiece with 170.9 N at 0.5 MPa, securing parts for accurate hole placement in a small bench fixture.
Small Part Ejection
In a parts feeder, retract a pin to release a 25 mm bore-sized component from a nest, with the spring extending it back for the next cycle.
Lab Test Rig
In a materials tester, pull a probe or gripper with a controlled 170.9 N force at 0.5 MPa to measure adhesion or spring rate on small samples.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE25X5B the Right Cylinder?
For smaller tasks, consider the ATE20X5B with 88.1 N pull at 0.5 MPa, or step up to the ATE32X25B for 296.0 N if you need more force. This 5 mm stroke is short, so it suits precise, small movements rather than long travel. The male rod thread (B code) simplifies mounting with rod-end accessories, and the M5x0.8 port is standard for this bore. Remember, on air loss the spring returns the rod to its extended position, so it does not hold a mid-stroke load.
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 ATE25X5B FAQ
At 0.5 MPa, the net pull force is 170.9 N, and at 0.7 MPa it is 253.3 N, both already accounting for the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
No, this model has no magnet because the -S code was not ordered. To use CMSE or DMSE switches, you must order the ATE25X5SB version, which includes the optional magnet. The cylinder body has slots for the sensors, but the magnet is required for them to work.
