Airtac ATE Single Acting Guided Compact Cylinder ATE20X5SB
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE20X5SB 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 ATE20X5SB
This AirTAC ATE20X5SB is a single acting pull cylinder, meaning a spring extends the rod and air retracts it, with the 88.1 N pull force at 0.5 MPa already net of the return spring. Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, making it a fit for tight fixtures where a full-length unit won't go.
With the optional -S magnet fitted, you can mount CMSE or DMSE switches for position sensing. For a real-world load, plan for about 5.4 kg of safe vertical work at 0.5 MPa, which is roughly 60% of the rated force, 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 ATE20X5SB Is Used
Small Part Ejection
Use the 5 mm stroke to eject small stamped components from a die or nest in a compact press, where the short body fits between the die plates and the 88.1 N pull clears the part.
Tensioner Release
In a light assembly fixture, this cylinder can retract a tensioner arm to release a belt or cable. The spring return ensures the arm extends to its home position when air is removed.
Gauge Positioning
Move a small dial indicator or sensor probe into position for a quick measurement cycle. The 5 mm travel is ideal for a check-and-retract sequence, and the compact body fits on a crowded inspection station.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE20X5SB the Right Cylinder?
For a lighter pull, the 16 mm bore ATE16X25 offers 53.3 N at 0.5 MPa, while stepping up to the 25 mm bore ATE25X25 provides 170.9 N at the same pressure. This 20 mm bore model with a 5 mm stroke suits short, precise movements where space is tight. Remember, the spring returns the rod to its extended position on air loss, so it does not hold a mid-stroke position.
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 ATE20X5SB FAQ
This single acting pull cylinder delivers 88.1 N at 0.5 MPa and 135.2 N at 0.7 MPa, 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 body is about 50% shorter than an ISO 15552 profile cylinder, which is a major advantage in tight spaces. The fixed TPU bumper at both ends absorbs energy at stroke end, and this model includes the optional -S magnet for use with CMSE or DMSE switches.
