Airtac ATE Single Acting Guided Compact Cylinder ATE40X20B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE40X20B is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø40mm bore and 20mm 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 ATE40X20B
This AirTAC ATE40X20B is a single acting pull cylinder with a spring return, so the spring extends the rod and air retracts it. At 0.5 MPa it delivers 500.3 N of pull force net of the spring, and at 0.7 MPa that rises to 729 N, making it a solid choice for light assembly and clamping tasks.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which lets it fit into tight machine guards and gantries. With a male rod thread (B code) and a 1/8" port, it is ready to bolt into standard fixtures. For a safe working load, plan for about 300 N of real work at 0.5 MPa, which translates to lifting roughly 31 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 ATE40X20B Is Used
Jig Clamping
Use the ATE40X20B to clamp small parts in a CNC fixture, where the 500.3 N pull at 0.5 MPa holds components securely during drilling or milling operations.
Sorting Gate
In a packaging line, this cylinder can retract a stop gate to divert products, with its 20 mm stroke and spring return ensuring the gate resets automatically when air is removed.
Test Rig Actuator
For a quality lab, the ATE40X20B can pull a test probe into contact with a sample, using its 729 N pull at 0.7 MPa to apply a consistent force for measurement cycles.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE40X20B the Right Cylinder?
For a lighter pull, consider the ATE32X25 with 296.0 N at 0.5 MPa, or step up to the ATE50X25 for 775.0 N at the same pressure. This 40 mm bore offers a balanced force for medium-duty applications. Remember, the spring returns the rod to its extended position on air loss, so it does not hold a mid-stroke load. The optional -S magnet is not fitted here, so no sensors can be mounted without ordering that code.
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 ATE40X20B FAQ
At 0.5 MPa, the pull force is 500.3 N, and at 0.7 MPa, it is 729 N, both net of the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, saving mounting space in tight areas. It has a fixed TPU bumper at both ends to absorb end-of-stroke energy, and the optional -S magnet is required for CMSE or DMSE sensors.
