Airtac ATE Single Acting Guided Compact Cylinder ATE25X5
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE25X5 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 ATE25X5
This AirTAC ATE25X5 is a single acting pull cylinder with a spring return, so the spring extends the rod and air retracts it. At 0.5 MPa it delivers 170.9 N of pull force, net of the return spring, and at 0.7 MPa that rises to 253.3 N. The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which lets it fit into tight machine guards and gantries where a full-length cylinder will not. For a real-world check, the 170.9 N pull at 0.5 MPa translates to lifting about 10 kg vertically with a 2:1 safety margin, so you can match it against actual part weights.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling, while the fixed TPU bumper at both ends absorbs end-of-stroke impact. This model has no magnet fitted, so it cannot accept CMSE or DMSE sensors; order the optional -S code if you need position sensing. The M5x0.8 port suits small-bore piping, and the female M6x1.0 rod thread connects directly to standard clevis or rod-end accessories.

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 ATE25X5 Is Used
Small Jig Clamping
Use the ATE25X5 to pull a clamp arm onto a small fixture in a CNC workholding setup, where the 5 mm stroke and 170.9 N pull at 0.5 MPa provide a firm hold without taking up much space on the machine table.
Label Applicator Retract
In a packaging line, this cylinder can retract a label tamp pad after application, with the spring extending it back to the ready position. The short stroke and compact body fit between guide rails, and the fixed TPU bumper prevents noise at cycle rates up to 500 mm/s.
Guard Door Latch Pull
Mount the ATE25X5 on a machine guard to pull a latch pin out of a hole for access, then let the spring re-engage it on air release. The 5 mm stroke is enough for a positive detent, and the compact body keeps the mechanism flush with the frame.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE25X5 the Right Cylinder?
For a lighter pull, the ATE20X25 delivers 88.1 N at 0.5 MPa, while stepping up to the ATE32X25 gives 296.0 N at the same pressure, so you can scale the force to the job. Because this is a spring-extend cylinder, it returns to the extended position on air loss, but it does not hold a mid-stroke position, so plan your circuit accordingly. The compact ISO 21287 body accepts FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets, and the optional -S magnet enables CMSE or DMSE switches for end-of-stroke detection.
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 ATE25X5 FAQ
The ATE25X5 is single acting pull, spring extend, with forces net of the return spring. At 0.5 MPa it pulls 170.9 N, and at 0.7 MPa it pulls 253.3 N. The minimum working pressure is 0.2 MPa, and the maximum is 1.0 MPa (28-145 psi). Proof pressure is 1.5 MPa (215 psi), and the operating temperature range is -20 to +70 C.
The ATE25X5 uses the ISO 21287 compact format, which saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight spaces. This model has no magnet fitted, so it cannot accept CMSE or DMSE sensors. If you need position sensing, order the ATE25X5S version with the optional -S magnet. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the M5x0.8 port is standard for this 25 mm bore.
