Airtac ATE Single Acting Guided Compact Cylinder ATE25X5S
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE25X5S is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø25mm bore and 5mm 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 ATE25X5S
This AirTAC ATE25X5S is a single acting pull cylinder, spring-return, where the spring extends the rod and air retracts it. With a 25 mm bore and 5 mm stroke, it delivers 170.9 N of pull at 0.5 MPa, net of the return spring, and 253.3 N at 0.7 MPa.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, fitting tight machine guards and indexing fixtures. The included -S magnet enables CMSE or DMSE sensors for position feedback, and at 0.5 MPa this unit safely handles about 10 kg of vertical work with a 2:1 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 (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 ATE25X5S Is Used
Small Part Ejector
Use the 5 mm stroke to pop a stamped washer off a locating pin in a press die, with the spring holding the ejector ready for the next cycle.
Label Applicator Tamp
Pull a vacuum cup back 5 mm to tamp a label onto a moving carton, using the compact body to fit between existing guide rails.
Sorting Gate Pin
Retract a 5 mm pin to release a small plastic part onto a chute in a vibratory feeder system, with the -S magnet confirming the pin position via a DMSE switch.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE25X5S the Right Cylinder?
For lighter duty, the 20 mm bore ATE20X25 pulls 88.1 N at 0.5 MPa, while stepping up to the 32 mm bore ATE32X25 gives 296.0 N. This 25 mm bore model suits short 5 mm strokes where a compact envelope is critical. Remember, the spring returns the rod to extended on air loss, so it does not hold a mid-stroke position. Choose the optional foot or flange mount to match 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 ATE25X5S FAQ
At 0.5 MPa the pull force is 170.9 N, and at 0.7 MPa it is 253.3 N. These figures are net of the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, making it ideal for tight jigs and gantries. The fixed TPU bumper absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE sensors for position detection.
