Airtac ATE Single Acting Guided Compact Cylinder ATE20X20S
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE20X20S is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø20mm bore and 20mm stroke, M5×0.8 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 ATE20X20S
This AirTAC ATE20X20S is a single acting pull cylinder where the spring extends the rod and air retracts it, making it ideal for fail-safe extended positions. With a 20 mm bore, it delivers 88.1 N of pull at 0.5 MPa, net of the return spring, and requires a minimum of 0.2 MPa to overcome spring force.
The ISO 21287 compact body is about 50% shorter than a profile cylinder, saving space in tight fixtures. This model carries the optional -S magnet, enabling CMSE or DMSE sensors. For real work, plan for about 5.4 kg of vertical lift at 0.5 MPa, giving you a practical margin for your application.

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 (Ø20mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 88.1 N |
| 0.7 MPa | 135.2 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 ATE20X20S Is Used
Jig Clamping
Use in a drill jig to pull a clamp arm down onto a small workpiece, with the spring holding the clamp open when air is off.
Label Applicator
Retract a label applicator head after each cycle on a packaging line, where the compact body fits between guide rails.
Small Gate Operator
Pull open a small safety gate on a machine guard, with the spring returning the gate to the closed position.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE20X20S the Right Cylinder?
For a smaller footprint, consider the ATE16X25 with 53.3 N pull, while the ATE25X25 offers a stronger 170.9 N pull at 0.5 MPa. This 20 mm bore model suits light clamping or positioning tasks where space is limited. The spring returns the rod to extended on air loss, but it does not hold a mid-stroke position. Mounting options include FA/FB flange, LB foot, and CA/CB clevis brackets.
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 ATE20X20S FAQ
At 0.5 MPa, the pull force is 88.1 N; at 0.7 MPa, it is 135.2 N. These figures are net of the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The ATE20X20S body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable mounting space. It features fixed TPU bumpers at both ends to absorb energy, and the optional -S magnet allows for CMSE or DMSE sensor mounting.
