About the Airtac ATE Single Acting Guided Compact Cylinder ATE25X15S
This AirTAC ATE25X15S is a compact ISO 21287 single acting pull cylinder, spring-extend type, where the spring pushes the rod out and air retracts it. At 0.5 MPa it delivers 170.9 N of pull force, net of the return spring, and at 0.7 MPa it reaches 253.3 N, making it suitable for light assembly tasks. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine guards and gantries where a full-length cylinder would not. With the optional -S magnet fitted, you can mount CMSE or DMSE reed switches for position sensing, which is useful for automated cycle confirmation.
For a real-world load, plan for about 10 kg of safe vertical work at 0.5 MPa, factoring a 2:1 margin from the 170.9 N rating. The hard-anodized aluminium body and S45C hard-chrome rod resist wear in repetitive pick-and-place operations. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the minimum working pressure is 0.2 MPa to overcome the spring. Port size is M5x0.8, and the rod thread is M6x1.0 female, so it connects to standard grippers or tooling.

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 ATE25X15S Is Used
Small Part Ejector
In a plastic injection mold, this cylinder retracts a core pin to release a small cap. The 170.9 N pull at 0.5 MPa clears the part, and the compact body fits between the mold plates without extra space.
Conveyor Gate Stop
On a light packaging line, the ATE25X15S pulls a stop pin down to let a carton pass. The spring extends the pin to block the next item, and the M5x0.8 port connects to a small solenoid valve for quick cycling.
Automated Clamp Release
In a PCB assembly fixture, this cylinder retracts a clamp to release a board after soldering. The optional -S magnet triggers a CMSE switch to confirm the clamp is open, ensuring the next board loads safely.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE25X15S the Right Cylinder?
When sizing, compare this 25 mm bore with the 20 mm bore, which pulls 88.1 N at 0.5 MPa, or the 32 mm bore at 296.0 N, to match your required force. This model suits short strokes up to 25 mm, and at 15 mm stroke it fits compact fixtures without over-travel. The spring-return action means the rod extends when air is off, so it does not hold a mid-stroke position; use it for simple retract operations. Choose the -S magnet version for sensor feedback, and pick from FA/FB flange, LB foot, or CA/CB clevis mounts to integrate with your frame.
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 ATE25X15S FAQ
At 0.5 MPa, the pull force is 170.9 N, and at 0.7 MPa it is 253.3 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 proof pressure is 1.5 MPa (215 psi).
The ATE25X15S body is about 50% shorter than an ISO 15552 profile cylinder, so it mounts in confined areas like machine guards or gantries. The fixed TPU bumper at both ends absorbs impact, and the optional -S magnet allows CMSE or DMSE sensors for position feedback.
