Airtac ATE Single Acting Guided Compact Cylinder ATE63X25B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE63X25B is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø63mm bore and 25mm stroke, 1/8" 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 ATE63X25B
This AirTAC ATE63X25B is a single acting pull cylinder with spring return, meaning the spring extends the rod and air retracts it. At 0.5 MPa it delivers a net pull of 1320 N, and at 0.7 MPa that rises to 1903.2 N, so it can handle moderate retraction tasks in tight spaces.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which lets it fit into cramped jigs and guards. With a 63 mm bore and 25 mm stroke, it offers a practical vertical lift of about 80 kg at 0.5 MPa when you apply a 2:1 safety margin, making it a solid choice for light lifting or clamping fixtures.

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 (Ø63mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 1320.0 N |
| 0.7 MPa | 1903.2 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 ATE63X25B Is Used
Jig Retraction
Use the ATE63X25B to retract a locating pin in a CNC fixture, where the spring extends the pin to locate the part and air pulls it back for unloading.
Gate Latch Pull
In a warehouse conveyor guard, this cylinder can pull a safety gate latch open on command, with the spring returning it to the locked position when air is removed.
Clamp Release
On a light assembly line, mount it to release a spring-loaded clamp after a part is placed, providing a controlled retraction force of 1320 N at 0.5 MPa.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE63X25B the Right Cylinder?
For a smaller option, the ATE50X25B offers a pull of 775 N at 0.5 MPa, while the ATE80X25B steps up to 2159.1 N at the same pressure. Since this is single acting pull, the spring returns the rod to its extended position on air loss; it does not hold a mid-stroke position, so plan for that behavior. The male rod thread (B code) suits direct coupling, and the 1/8" port is standard for this bore size.
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 ATE63X25B FAQ
At 0.5 MPa, the pull force is 1320 N, and at 0.7 MPa it is 1903.2 N, both net of 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 would need to order the ATE63X25SB variant, which includes the optional magnet for sensor mounting.
