Airtac ATE Single Acting Guided Compact Cylinder ATE12X5
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE12X5 is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø12mm 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 ATE12X5
This AirTAC ATE12X5 is a single acting pull cylinder, spring-return, where the spring extends the rod and air retracts it. With a 12 mm bore and 5 mm stroke, it delivers a net pull of 25.9 N at 0.5 MPa, making it suitable for light-duty retraction tasks in compact spaces.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, fitting into tight jigs and guards. The optional -S magnet is not fitted here, so no sensor can be mounted; order the -S code for CMSE or DMSE switches. For a safe working load, plan for about 15.5 N (0.6 x 25.9 N) of real work at 0.5 MPa, or roughly 1.6 kg vertical lift 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 (Ø12mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 25.9 N |
| 0.7 MPa | 42.9 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 ATE12X5 Is Used
Small Jig Clamping
Use the ATE12X5 to retract a small clamp in a precision assembly jig, where its 25.9 N pull at 0.5 MPa secures lightweight parts without over-stressing them.
Tight-Space Indexing
In a compact indexing table, this cylinder's 5 mm stroke and short ISO 21287 body fit into confined spaces, providing a reliable spring-extend pull for positioning small components.
Light Guard Retraction
For a machine guard that needs to retract a small latch, the ATE12X5 offers a simple, spring-return action that pulls the latch open when air is applied, ensuring safe operation in limited areas.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE12X5 the Right Cylinder?
Choose the ATE12X5 for applications needing a short, spring-extend pull with minimal force, such as small clamps or light indexing. Compare with the ATE16X25, which offers a net pull of 53.3 N at 0.5 MPa for more demanding tasks. On air loss, the spring returns the rod to its extended home position, but 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, fitting standard ISO 21287 faces.
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 ATE12X5 FAQ
The ATE12X5 provides a net pull of 25.9 N at 0.5 MPa and 42.9 N at 0.7 MPa, with forces already accounting for the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
Yes, it is an ISO 21287 compact cylinder with a hard-anodized aluminium body, about 50% shorter than an ISO 15552 profile cylinder. The magnet is optional; this model has no magnet, so sensors like CMSE or DMSE require ordering the -S code. It features fixed TPU bumpers at both ends for end-of-stroke deceleration.
