Airtac ATE Single Acting Guided Compact Cylinder ATE40X15
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE40X15 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 ATE40X15
This ATE40X15 is a single acting pull cylinder, meaning its spring extends the rod and air retracts it, with a net pull force of 500.3 N at 0.5 MPa. Its compact ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, making it ideal for tight spaces in automated assembly cells.
With a 40 mm bore and 15 mm stroke, this unit fits into fixtures where a longer cylinder would not. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper absorbs end-of-stroke impact. For a safe working load, plan for about 300 N of real work at 0.5 MPa, which translates to lifting roughly 30 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 (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 ATE40X15 Is Used
Jig Clamping
Use in a CNC machine fixture to pull a clamp arm down onto a workpiece, with the spring extending the arm when air is released for quick part changes.
Gate Actuator
Mount on a small conveyor line to retract a stop gate, allowing a box to pass, then the spring returns the gate to block the next item.
Label Applicator
In a packaging machine, retract a label applicator head after it presses a label onto a product, with the spring returning it to the ready position.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE40X15 the Right Cylinder?
When sizing, consider that a smaller 32 mm bore offers 296 N pull at 0.5 MPa, while a larger 50 mm bore provides 775 N pull at the same pressure. This 40 mm model sits between them, offering a balance of force and compactness for medium-duty applications. The spring returns the rod to its extended position on air loss, but it does not hold a mid-stroke position, so use it for simple pull actions. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, and the optional -S magnet enables CMSE or DMSE sensors for position feedback.
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 ATE40X15 FAQ
The ATE40X15 provides a net pull force of 500.3 N at 0.5 MPa and 729 N at 0.7 MPa, with these values already accounting for the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The ISO 21287 compact body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits into tight machine guards and gantries. It has a fixed TPU bumper at both ends to absorb impact, and mounting options like FA/FB flange, LB foot, and CA/CB clevis bolt directly to the standard face.
