About the Airtac ATE Single Acting Guided Compact Cylinder ATE40X5SB
This AirTAC ATE40X5SB is a single acting pull cylinder with spring return, meaning the spring extends the rod and air retracts it. At 0.5 MPa it delivers a net pull of 500.3 N, and at 0.7 MPa that rises to 729 N, so it can handle moderate clamping or lifting tasks in a compact envelope.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight fixtures. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing. For a real-world load, plan on about 30 kg of safe vertical lift at 0.5 MPa, accounting for a 2:1 safety 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 ATE40X5SB Is Used
Fixture Clamping
Use the ATE40X5SB to pull a clamp arm down onto a workpiece in a CNC fixture, delivering 500.3 N of holding force at 0.5 MPa in a compact space.
Gate Actuation
In a packaging line, this cylinder can retract a small diverter gate to redirect products, with a 5 mm stroke that is fast and precise at speeds up to 500 mm/s.
Press Guard Interlock
Mount it to pull a safety guard closed on a small press, using the spring-extend fail-safe to keep the guard in place when air pressure is lost.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE40X5SB the Right Cylinder?
For a smaller option, the ATE32X25 offers 296 N pull at 0.5 MPa, while the ATE50X25 provides 775 N. This 40 mm bore with a 5 mm stroke suits short, precise pull actions where space is limited. Remember, on air loss the spring returns the rod to its extended home position, 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 ATE40X5SB FAQ
The ATE40X5SB delivers a net pull of 500.3 N at 0.5 MPa and 729 N at 0.7 MPa, both figures 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 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight jigs and guards. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE sensors for position feedback.
