Airtac ATE Single Acting Guided Compact Cylinder ATE25X5SB
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE25X5SB 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 ATE25X5SB
This AirTAC ATE25X5SB is a single acting pull, spring-return compact cylinder, so the spring extends the rod and air retracts it. At 0.5 MPa it delivers a net pull of 170.9 N, and at 0.7 MPa that rises to 253.3 N, with the spring force already subtracted.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which suits tight fixtures and gantries. The optional -S magnet is fitted here, so CMSE or DMSE switches can be mounted, and the male rod thread (B) simplifies linkage. For a safe working load, plan for about 0.6 times the 0.5 MPa rating, which is roughly 103 N, or about 10 kg vertically 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 ATE25X5SB Is Used
Fixture Clamp Retract
Use the 5 mm stroke to retract a locating pin or clamp in a small jig, with the spring extending it to the home position when air is released.
Label Applicator Pull
In a labeling machine, this cylinder can pull a tensioner arm back 5 mm to release a label web, relying on the spring to re-tension it.
Guard Door Latch
Mount it on a machine guard to retract a spring-loaded latch, allowing the guard to open, with the spring returning the latch to the locked position.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE25X5SB the Right Cylinder?
For a smaller option, the ATE20X5 offers 88.1 N at 0.5 MPa, while stepping up to the ATE32X5 gives 296.0 N. Since this is a spring-extend cylinder, it returns to the extended position on air loss, so it does not hold a mid-stroke position. The M5x0.8 port suits small-bore circuits, and the male rod thread (B) is ready for direct coupling.
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 ATE25X5SB FAQ
The net pull force, already accounting for the return spring, is 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa. 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 of an ISO 15552 profile cylinder, making it ideal for tight spaces. It has a fixed TPU bumper at both ends, and the optional -S magnet allows mounting CMSE or DMSE sensors.
