Airtac ATE Single Acting Guided Compact Cylinder ATE25X15
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE25X15 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 ATE25X15
This AirTAC ATE25X15 is a single acting pull cylinder with a spring-return design, meaning the spring extends the rod and compressed air retracts it. At 0.5 MPa it delivers a net pull of 170.9 N, rising to 253.3 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa. The ISO 21287 compact body takes up about 50% less mounting length than an ISO 15552 profile cylinder, making it ideal for tight machine guards and indexing fixtures.
For a 2:1 safety margin, plan to lift about 8.7 kg vertically with this bore at 0.5 MPa, or size it for roughly 103 N of continuous work. The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in high-cycle applications, while the fixed TPU bumper at both ends absorbs end-of-stroke impact without adjustment. Since this unit has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be mounted on it.

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 ATE25X15 Is Used
Jig Clamping
Use the 170.9 N pull at 0.5 MPa to retract a spring-loaded clamp pin in a drill jig, holding thin sheet metal parts securely during machining operations.
Carton Tabbing
In a carton erecting machine, this cylinder pulls a folding tab into place on a 15 mm stroke, cycling at up to 500 mm/s to keep pace with a packaging line.
Sortation Gate
Retract a small diverter gate on a gravity conveyor to route parcels to a secondary lane, with the spring return resetting the gate when air is removed.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE25X15 the Right Cylinder?
When sizing, compare this 25 mm bore against the 20 mm bore which pulls 88.1 N at 0.5 MPa for lighter pick-and-place tasks, or step up to the 32 mm bore with 296.0 N at 0.5 MPa for heavier clamping work. The 15 mm stroke suits short transfer slides and compact clamping mechanisms where space is limited. Remember that on air loss the spring returns the rod to its extended position, so it will not hold a mid-stroke load. The M5x0.8 port accepts standard fittings, and the female M6x1.0 rod thread connects directly to your tooling.
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 ATE25X15 FAQ
The ATE25X15 delivers a net pull of 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa, with forces already accounting for the return spring. Minimum working pressure is 0.2 MPa, proof pressure is 1.5 MPa (215 psi), and operating pressure range is 0.2-1.0 MPa (28-145 psi). Operating speed is 50-500 mm/s.
No, this specific unit has no magnet because the -S code was not ordered. The magnet is optional and only available when you order the -S suffix, which then allows CMSE or DMSE switches to be mounted. Without the -S code, there is no magnet and no sensor can be fitted. The fixed TPU bumper at both ends absorbs end-of-stroke impact.
