Airtac ATE Single Acting Guided Compact Cylinder ATE50X25S
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE50X25S is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø50mm 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 ATE50X25S
This AirTAC ATE50X25S 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 775 N, and at 0.7 MPa that rises to 1127.5 N, so you can size it for real work without derating for the spring.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which helps it fit into tight machine frames and guarding. The optional -S magnet is fitted here, so you can mount CMSE or DMSE reed or solid-state switches for position sensing. As a rule of thumb, plan for about 465 N of safe working load at 0.5 MPa, or roughly 47 kg of vertical lift with a 2:1 safety margin.

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 (Ø50mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 775.0 N |
| 0.7 MPa | 1127.5 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 ATE50X25S Is Used
Jig Clamp Retract
Use the 775 N pull to retract a clamping arm on a CNC fixture, where the spring extends the clamp into place and air pulls it clear for part loading.
Conveyor Stop Release
On a packaging line, this cylinder can pull a stop pin down to let a carton pass, with the spring returning the pin to block the next item.
Sorting Gate Actuator
In a warehouse sortation system, the ATE50X25S retracts a diverter gate to route parcels to a different lane, relying on the spring for fail-safe return.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE50X25S the Right Cylinder?
For a lighter pull, the ATE32X25 offers 296 N at 0.5 MPa, while stepping up to the ATE63X25 gives 1320 N at the same pressure. This 50 mm bore sits in the middle of the range, suitable for medium-duty retract tasks. Since it is single acting pull, the spring returns the rod to its extended home position on air loss; it does not hold a mid-stroke position. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all matching the ISO 21287 face.
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 ATE50X25S FAQ
The ATE50X25S delivers a net pull of 775 N at 0.5 MPa and 1127.5 N at 0.7 MPa, with the spring force already subtracted. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi). Operating pressure range is 0.2-1.0 MPa (28-145 psi).
The ATE50X25S uses a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, saving mounting length in confined machine areas. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE switch mounting for position feedback.
