About the Airtac ATE Single Acting Guided Compact Cylinder ATE40X5S
This ATE40X5S 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 500.3 N of pull force at 0.5 MPa, net of the return spring, making it a compact workhorse for light automation tasks.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine guards and gantries. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing. For a safe vertical lift, plan for about 30 kg (0.6 x 500.3 N divided by 9.81) to keep 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 ATE40X5S Is Used
Jig Clamping
Use in a CNC fixture to pull a clamp arm 5 mm, securing small parts during drilling. The 500.3 N pull at 0.5 MPa holds parts firmly, and the short body fits under the spindle guard.
Sorting Gate
Mount on a packaging conveyor to retract a 5 mm stop pin, diverting lightweight boxes. The spring extends the pin to block, and air pulls it clear for release, cycling at up to 500 mm/s.
Test Probe Actuator
In a quality lab, pull a sensor probe back 5 mm from a test piece. The compact body saves space on the test bench, and the TPU bumper absorbs end-of-stroke impact for quiet operation.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE40X5S the Right Cylinder?
When sizing, compare this 40 mm bore with the 32 mm bore (296.0 N at 0.5 MPa) for lighter loads, or the 50 mm bore (775.0 N) for heavier pulls. The 5 mm stroke suits short indexing moves; the spring returns the rod to extended on air loss, so 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, all compatible with the ISO 21287 face.
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 ATE40X5S FAQ
The ATE40X5S delivers 500.3 N of pull at 0.5 MPa and 729 N at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, proof pressure is 1.5 MPa (215 psi), and speed range is 50-500 mm/s.
This model carries the optional -S magnet, so you can attach CMSE or DMSE reed or solid-state switches for position sensing. The ISO 21287 compact body accepts FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, and the fixed TPU bumper decelerates at both ends.
