About the Airtac ATE Single Acting Guided Compact Cylinder ATE20X15S
This ATE20X15S is a single acting pull cylinder, spring-return, from AirTAC's ISO 21287 compact line. Its spring extends the 10 mm rod, while air retracts it, delivering a net pull of 88.1 N at 0.5 MPa, enough for light clamping or indexing tasks. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine guards and compact jigs where space is limited.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in repetitive cycles. This model includes the optional -S magnet, so you can fit CMSE or DMSE reed switches for position sensing. For a safe working load, plan for about 53 N of real work at 0.5 MPa, which translates to lifting roughly 5.4 kg vertically with a 2:1 safety margin, making it a practical choice for small part handling.

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 ATE20X15S Is Used
Jig Clamping
Use the 88.1 N pull at 0.5 MPa to retract a clamp pin in a small assembly jig, holding a component in place during a light press operation. The compact body fits under a workbench guard where a longer cylinder would not.
Sorting Gate
In a small conveyor line, this cylinder can pull a diverter flap to route lightweight parts into a reject bin. The spring extends the flap to its default position when air is off, ensuring fail-safe operation.
Bin Release
Mount this cylinder on a storage rack to pull a latch that releases a small parts bin. With a 15 mm stroke and 88.1 N force, it provides enough travel and strength to unclip a lightweight container for retrieval.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE20X15S the Right Cylinder?
When sizing, consider the bore 16 variant, which offers 53.3 N pull at 0.5 MPa, if you need a lighter option; or step up to bore 25 for 170.9 N pull at 0.5 MPa for heavier loads. This 20 mm bore unit suits applications where space is constrained and force requirements are moderate. Remember, the spring returns the rod to its extended position on air loss, so it does not hold a mid-stroke position. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with the ISO 21287 face.
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 ATE20X15S FAQ
The ATE20X15S delivers a net pull force of 88.1 N at 0.5 MPa and 135.2 N at 0.7 MPa, both figures already accounting for the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi). The operating pressure range is 0.2-1.0 MPa (28-145 psi).
The ATE20X15S uses a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, saving valuable mounting space in tight fixtures. It features a fixed TPU bumper at both ends to absorb end-of-stroke impact, and the optional -S magnet allows for CMSE or DMSE sensor mounting. The rod end is female with M6x1.0 thread, and the port is M5x0.8.
