Airtac ATE Single Acting Guided Compact Cylinder ATE12X5B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE12X5B 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 ATE12X5B
This is a genuine AirTAC ISO 21287 compact cylinder in a single acting pull configuration, with the spring extending the rod and air retracting it. With a 12 mm bore, it delivers a net pull of 25.9 N at 0.5 MPa and 42.9 N at 0.7 MPa, and it requires a minimum of 0.2 MPa to overcome the return spring.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight jigs and guards. This version has a male rod thread (B code) and no magnet, so it cannot be used with CMSE or DMSE sensors unless you order the optional -S variant. As a rule of thumb, you can plan for about 1.6 kg of real vertical work at 0.5 MPa, which is roughly 60% of the rated pull.

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 ATE12X5B Is Used
Tiny Clamp Release
Use the 5 mm stroke to release a small spring-loaded clamp on a benchtop assembly fixture, where the compact body fits under the work surface.
Miniature Gate Pin
Pull a locating pin out of a guide hole in a small automated inspection station, with the short stroke providing fast, repeatable retraction.
Lab Valve Actuator
Retract a small flow-control valve stem in a test rig, where the 25.9 N pull at 0.5 MPa is sufficient and the short body saves bench space.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE12X5B the Right Cylinder?
For a lighter application, the ATE12X10 offers a longer standard stroke, while stepping up to the ATE16X25 provides a significantly higher 53.3 N pull at 0.5 MPa. This 5 mm stroke unit is for short, precise pull actions where space is at a premium. Remember, on air loss the spring returns the rod to its extended position; it does not hold a mid-stroke load. Choose the -S code if you need the optional magnet for position sensing, and consider FA/FB flange, LB foot, or CA/CB clevis mounts.
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 ATE12X5B FAQ
At 0.5 MPa, the net pull force is 25.9 N; at 0.7 MPa, it is 42.9 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).
It follows the ISO 21287 compact standard, saving about 50% of the mounting length of an ISO 15552 profile cylinder. This version has no magnet, so sensors are not an option unless you order the -S code, which adds the magnet for CMSE or DMSE switches.
