Airtac ATE Single Acting Guided Compact Cylinder ATE20X5
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE20X5 is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø20mm bore and 5mm 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 ATE20X5
This is a single acting pull cylinder from AirTAC's ATE series, built to the ISO 21287 compact standard. The spring extends the rod at rest, and air pressure retracts it, delivering a net pull of 88.1 N at 0.5 MPa. Its short body takes up about half the mounting length of an ISO 15552 profile cylinder, making it ideal for tight spaces in automated assembly fixtures.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling. A fixed TPU bumper at each end absorbs impact, and the minimum working pressure is 0.2 MPa. For a 5 mm stroke, this unit can safely handle a vertical load of about 5.4 kg, calculated from the 0.5 MPa force with 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 (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 ATE20X5 Is Used
Tight-Fit Jig Clamping
Use the ATE20X5 to retract a locating pin in a compact jig where a full-length cylinder won't fit. The 5 mm stroke and 88.1 N pull are enough to clear small parts between cycles.
Small Parts Ejection
In a small assembly machine, this cylinder can pull back a spring-loaded ejector blade. The short stroke and fixed TPU bumper provide quick, quiet operation for parts up to about 5 kg.
Gate Locking on a Guard
Mount this compact unit on a machine guard to retract a spring-loaded locking bolt. The spring-extend action keeps the guard locked when air is off, enhancing safety in a small footprint.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE20X5 the Right Cylinder?
For a 20 mm bore, this ATE20X5 provides 88.1 N of pull at 0.5 MPa. If you need less force, the 16 mm bore offers 53.3 N at the same pressure, while stepping up to a 25 mm bore gives you 170.9 N. This model has a 5 mm stroke, which is well within the 25 mm maximum standard stroke for this bore size. Note that the spring returns the rod to its extended position on air loss; it does not hold a mid-stroke position. This version has no magnet, so it cannot be used with sensors; order the -S code if you need that option.
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 ATE20X5 FAQ
The ATE20X5 delivers 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. It operates from 0.2 to 1.0 MPa (28-145 psi) and has a proof pressure of 1.5 MPa (215 psi).
No, this specific model without the -S code has no magnet, so CMSE or DMSE sensors cannot be mounted. If you need position sensing, you must order the ATE20X5S variant, which includes the optional magnet. The compact ISO 21287 body has slots for these sensors.
