Airtac ATE Single Acting Guided Compact Cylinder ATE20X20
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE20X20 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 ATE20X20
This AirTAC ATE20X20 is a single acting pull cylinder, spring-return, where the spring extends the rod and air retracts it, delivering a net pull of 88.1 N at 0.5 MPa. Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, fitting into tight machine guards and gantries where full-length cylinders won't go.
With a 20 mm bore and 20 mm stroke, this unit uses a hard-anodized aluminium body and S45C hard-chrome rod for wear resistance. Since it has no magnet (the -S code is optional), it cannot accept CMSE or DMSE sensors unless ordered with that option. At 0.5 MPa, a safe working load of about 53 N (roughly 5.4 kg) is a practical planning figure for real applications.

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 ATE20X20 Is Used
Jig clamping pull
Use the ATE20X20 to pull a clamp arm tight against a workpiece in a CNC fixture, where its 88.1 N pull at 0.5 MPa secures small parts during drilling or milling.
Label applicator retract
In a packaging line, this cylinder retracts a label applicator head after each cycle, with the spring extending it back to the ready position, handling speeds up to 500 mm/s.
Guard door latch
Mount it on a machine guard door to pull a latch pin out of a hole when air is applied, and let the spring re-engage the pin on air loss, ensuring the door stays locked in a power failure.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE20X20 the Right Cylinder?
For a lighter duty, consider the ATE16X25 with a 53.3 N pull at 0.5 MPa, while the ATE25X25 offers a stronger 170.9 N pull at the same pressure. This ATE20X20 suits short-stroke pull tasks up to 25 mm, but note that on air loss the spring returns the rod to its extended home position, so it does not hold a mid-stroke load. Choose from FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC brackets to match your fixture, and order the -S code if you need sensor 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 ATE20X20 FAQ
The ATE20X20 provides a net pull of 88.1 N at 0.5 MPa and 135.2 N at 0.7 MPa, with forces already accounting for the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
Only if you order the optional -S magnet code. Without the -S code, this ATE20X20 has no magnet, so CMSE or DMSE switches cannot be mounted. The compact ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and the fixed TPU bumper absorbs end-of-stroke impact.
