Airtac ATE Single Acting Guided Compact Cylinder ATE16X20
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE16X20 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 ATE16X20
This AirTAC ATE16X20 is a single acting pull cylinder with a spring that extends the rod and air that retracts it, so it rests extended and fails safe to that position. At 0.5 MPa it delivers 53.3 N of pull force net of the spring, and at 0.7 MPa that rises to 83.5 N, making it a compact choice for light indexing or clamping tasks.
Its ISO 21287 short body takes up about 50% less mounting length than an ISO 15552 profile cylinder, which helps in tight machine guards or gantries. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, and the fixed TPU bumper at both ends absorbs end-of-stroke impact. For a real-world load, plan on about 3.3 kg of safe vertical lift at 0.5 MPa, so it suits small parts handling rather than heavy pushing.

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 ATE16X20 Is Used
Small Jig Clamping
Use the ATE16X20 to pull a small clamp arm onto a workpiece in a benchtop assembly jig, where the 53.3 N pull at 0.5 MPa secures light plastic or aluminum parts without over-stressing them.
Light Gate Stop
In a packaging line, this cylinder can retract a small stop pin to let a lightweight carton pass, then the spring extends it back to block the next item, cycling at speeds up to 500 mm/s.
Test Fixture Latch
For a quality-control fixture that checks small electronic housings, the ATE16X20 pulls a latch to release the part after inspection, with the spring returning the latch for the next cycle.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE16X20 the Right Cylinder?
When sizing, compare this 16 mm bore against the 12 mm bore, which pulls 25.9 N at 0.5 MPa, or the 20 mm bore at 88.1 N for a bit more force. The 20 mm stroke is within the standard 75 mm maximum for this bore, so no made-to-order lead time applies. Remember this cylinder does not hold a mid-stroke position; on air loss the spring returns the rod to its extended home, so use it for simple pull actions, not for load holding. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all fitting the ISO 21287 face. The optional -S magnet is not fitted here, so no CMSE or DMSE sensor can be used without ordering that code.
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 ATE16X20 FAQ
The ATE16X20 is single acting pull, so the spring extends the rod and air retracts it. The pull force is 53.3 N at 0.5 MPa and 83.5 N at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The ATE16X20 uses an ISO 21287 compact body that is about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it fits into narrow machine frames or behind guards. The fixed TPU bumper absorbs end-of-stroke impact, and the M5x0.8 port keeps plumbing simple. The optional -S magnet is not included, so order it if you need CMSE or DMSE sensors.
