Airtac ATE Single Acting Guided Compact Cylinder ATE25X25
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE25X25 is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø25mm bore and 25mm 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 ATE25X25
This 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 and 253.3 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa to overcome the spring.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable space in tight fixtures. The optional -S magnet enables CMSE or DMSE sensors for position detection, while the fixed TPU bumper absorbs end-of-stroke impact. For a real-world estimate, this cylinder can safely handle about 10 kg of vertical load with a 2:1 safety margin at 0.5 MPa.

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 ATE25X25 Is Used
Jig Clamping
Use in a drilling jig to pull a clamp arm down onto a workpiece, with the spring holding the clamp open when air is off.
Label Applicator
Retract a label applicator head to apply labels to products on a conveyor, with the spring returning the head to its ready position.
Safety Guard Lock
Pull a safety guard closed over a machine access point, with the spring keeping the guard open when the machine is idle.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE25X25 the Right Cylinder?
For lighter tasks, the ATE20X25 offers 88.1 N pull at 0.5 MPa, while the ATE32X25 provides 296.0 N for heavier work. Since this is a spring-extend cylinder, it returns to the extended position on air loss and does not hold a mid-stroke position. Choose the -S code if you need the magnet for CMSE or DMSE switches, and select FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC mounting brackets to fit your fixture.
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 ATE25X25 FAQ
The ATE25X25 delivers a net pull of 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa and a proof pressure of 1.5 MPa (215 psi). The operating pressure range is 0.2-1.0 MPa (28-145 psi).
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, making it ideal for tight spaces. The fixed TPU bumper absorbs end-of-stroke impact, and the optional -S magnet allows for CMSE or DMSE sensor mounting.
