Airtac ATE Single Acting Guided Compact Cylinder ATE40X15B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE40X15B is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø40mm bore and 15mm stroke, 1/8" 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 ATE40X15B
This AirTAC ATE40X15B is a single acting pull cylinder with spring return, meaning the spring extends the rod and air retracts it. With a 40 mm bore, it delivers a net pull force of 500.3 N at 0.5 MPa and 729 N at 0.7 MPa, ready for light assembly tasks.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, so it fits tight machine guards. The male rod thread (B code) simplifies linkage, and the fixed TPU bumper absorbs end-of-stroke impact. For a safe working load, plan around 300 N (about 30 kg) at 0.5 MPa to leave a margin for real-world friction and side loads.

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 (Ø40mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 500.3 N |
| 0.7 MPa | 729.0 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 ATE40X15B Is Used
Clamping fixture release
Use the 500 N pull to retract a spring-loaded clamp pin in a CNC fixture, freeing a part after machining. The compact body fits under the workholding plate.
Carton flap pull-down
Retract a flap on a packaging line with a 15 mm stroke, pulling it into a gluing station. The 40 mm bore provides enough force for light cardboard without crushing it.
Gate latch retraction
Pull a safety gate latch on a small automated press. The spring extends the latch to lock the gate when air is off, meeting fail-safe requirements.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE40X15B the Right Cylinder?
For a lighter pull, consider the ATE32X25 with 296 N at 0.5 MPa, or step up to the ATE50X25 for 775 N. This 40 mm bore suits short-stroke pull actions up to 25 mm standard. Since it is spring-extend, it returns to the extended position on air loss, but it does not hold a mid-stroke load. Choose the -S code if you need a magnet for CMSE or DMSE sensors; this model has no magnet.
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 ATE40X15B FAQ
At 0.5 MPa, the net pull force is 500.3 N; at 0.7 MPa, it is 729 N. These are net of the return spring, so they are the usable forces. Minimum working pressure is 0.2 MPa, and proof pressure is 1.5 MPa (215 psi).
The ATE40X15B body is about 50% shorter than an ISO 15552 profile cylinder, saving mounting length in confined areas. It has a fixed TPU bumper at both ends to absorb impact, and the male rod thread (B) allows direct coupling. The optional -S magnet enables CMSE or DMSE sensors, but this model has no magnet.
