Airtac ATE Single Acting Guided Compact Cylinder ATE20X5S
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE20X5S 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 ATE20X5S
This AirTAC ATE20X5S is a single acting pull cylinder with a spring return, meaning the spring extends the rod while air retracts it. At 0.5 MPa, it delivers a net pull force of 88.1 N, which translates to a safe working load of about 53 N or roughly 5.4 kg for vertical lifting applications. The short ISO 21287 body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, making it ideal for tight spaces.
The 20 mm bore unit has a 5 mm stroke and a 10 mm hard-chrome plated S45C rod. This model includes the optional -S magnet, so you can mount CMSE or DMSE reed switches for position sensing. The hard-anodized aluminium body and fixed TPU bumpers at both ends ensure durability and smooth deceleration at stroke limits.

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 ATE20X5S Is Used
Compact Jig Clamping
Use the 5 mm stroke to pull a clamp arm in a tight CNC fixture where a full-length cylinder cannot fit. The short body saves valuable machine envelope.
Small Part Ejector
Retract a pin to release small stamped parts from a die. The 88.1 N pull at 0.5 MPa is sufficient for lightweight components in a press.
Automated Sorting Gate
Pull a diverter flap in a small parts conveyor. The built-in -S magnet allows CMSE switches to confirm the gate position for reliable sorting.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE20X5S the Right Cylinder?
For a lighter application, consider the 16 mm bore ATE16X25S which provides 53.3 N pull at 0.5 MPa. If you need more force, the 25 mm bore ATE25X25S offers 170.9 N pull at the same pressure. Remember, this is a spring-extend cylinder, so it returns to the extended position on air loss and does not hold a mid-stroke position. The M5x0.8 port and female M6x1.0 rod thread are standard for this size.
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 ATE20X5S FAQ
The ATE20X5S provides a net pull force of 88.1 N at 0.5 MPa and 135.2 N at 0.7 MPa, with these values already accounting for the return spring. The minimum working pressure is 0.2 MPa, and the maximum is 1.0 MPa (145 psi).
The ISO 21287 body is about 50% shorter than a standard ISO 15552 profile cylinder, saving significant mounting space. It also features fixed TPU bumpers for end-of-stroke impact absorption, and this model includes the optional -S magnet for use with CMSE or DMSE sensors.
