Airtac ATE Single Acting Guided Compact Cylinder ATE16X20S
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE16X20S is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø16mm 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 ATE16X20S
This AirTAC ATE16X20S is a single acting pull cylinder with spring return, meaning the spring extends the rod and air retracts it, with forces already net of the spring. Its compact ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, making it ideal for tight spaces where a full-length unit won't fit.
At 0.5 MPa, this 16 mm bore unit delivers a net pull of 53.3 N, while at 0.7 MPa it reaches 83.5 N. As a practical guide, you can plan for about 32 N of real work at 0.5 MPa, which translates to lifting roughly 3.3 kg vertically with a 2:1 safety margin. The optional -S magnet is fitted on this model, enabling CMSE or DMSE switches for position sensing.

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 (Ø16mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 53.3 N |
| 0.7 MPa | 83.5 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 ATE16X20S Is Used
Small Parts Ejector
Use the 53.3 N pull at 0.5 MPa to retract a pin that releases small stamped components from a die in a bench press, with the spring extending the pin for the next cycle.
Jig Clamp Release
In a manual assembly jig, this cylinder's pull action releases a lightweight clamp arm, while the spring return resets it, speeding up repetitive part loading in a workshop.
Lab Valve Actuator
Actuate a small pinch valve on a fluid line in a test rig, using the 83.5 N pull at 0.7 MPa to close the line and the spring to reopen it, ensuring a fail-safe open state.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE16X20S the Right Cylinder?
For lighter tasks, the ATE12X10 offers a 25.9 N pull at 0.5 MPa, while stepping up to the ATE20X25 provides 88.1 N at the same pressure. Remember, this spring-extend cylinder does not hold a mid-stroke position on air loss; it returns to its extended home position. The M5x0.8 port and female M4x0.7 rod thread suit small-scale automation fixtures.
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 ATE16X20S FAQ
The ATE16X20S provides a net pull force of 53.3 N at 0.5 MPa and 83.5 N at 0.7 MPa, with these values already accounting for the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
This specific model includes the optional -S magnet, which is not standard on all ATE cylinders. With this magnet fitted, you can mount CMSE or DMSE reed or solid-state switches to detect the piston position. The fixed TPU bumper at both ends absorbs energy at stroke limits.
