Airtac ATE Single Acting Guided Compact Cylinder ATE80X20S
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE80X20S is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø80mm bore and 20mm stroke, 1/4" 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 ATE80X20S
This is a single acting pull cylinder with spring return, designed to retract loads when air is applied. The spring extends the rod at rest, and air pressure pulls it back, with forces already net of the spring. At 0.5 MPa, this 80 mm bore delivers 2159.1 N of pulling force, and at 0.7 MPa it reaches 3101.6 N, making it a strong choice for retraction tasks. The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable space in tight machine frames and guarding. With the optional -S magnet fitted, this model works with CMSE or DMSE switches for reliable position sensing, and the hard-anodized aluminium body resists wear in demanding environments.
For a safe working margin, plan for roughly 1295 N of real work at 0.5 MPa, not the full rating. This translates to lifting about 132 kg vertically with a 2:1 safety factor, helping you match it to actual part weights. The fixed TPU bumper at both ends absorbs end-of-stroke energy, protecting the cylinder and the load from impact. This model uses a 1/4" PT port and has a female M12x1.75 rod thread, fitting standard ISO 21287 accessories.

Theoretical Output Force (Ø80mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 2159.1 N |
| 0.7 MPa | 3101.6 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 ATE80X20S Is Used
Retract Clamp in Machining Fixture
Use the 2159.1 N pull at 0.5 MPa to retract a heavy-duty clamp arm in a CNC milling fixture. The compact body fits under the workholding table, and the spring extends the clamp to release the part when air is off.
Pull-Back Conveyor Stop
In a packaging line, this cylinder retracts a conveyor stop gate to let cartons pass. With 3101.6 N at 0.7 MPa, it handles high line speeds, and the TPU bumper prevents shock when the gate slams back.
Retract Guard Door on Press
Mount this cylinder to pull a safety guard door closed on a stamping press. The spring holds the door open at rest, and air retracts it firmly against the frame, with the optional -S magnet confirming the closed position via a DMSE switch.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE80X20S the Right Cylinder?
When sizing, consider that this 80 mm bore provides 2159.1 N of pull at 0.5 MPa, while a smaller 63 mm bore offers 1320.0 N at the same pressure. For lighter retraction tasks, the 63 mm bore may be more economical, but the 80 mm gives you a substantial force reserve. The spring returns the rod to its extended home position on air loss; it does not hold a mid-stroke position, so plan your circuit accordingly. With the -S magnet, you can mount CMSE or DMSE switches for position feedback, and the ISO 21287 face accepts FA/FB flange, LB foot, CA/CB clevis, and other standard brackets.
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 ATE80X20S FAQ
The ATE80X20S delivers 2159.1 N of pull at 0.5 MPa and 3101.6 N at 0.7 MPa, both net of the return spring. It operates from 0.2 MPa minimum pressure up to 1.0 MPa (28-145 psi), with a proof pressure of 1.5 MPa (215 psi). The spring extends the rod at rest, and air retracts it.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight spaces. The fixed TPU bumper absorbs end-of-stroke impact, and with the optional -S magnet, you can add CMSE or DMSE switches for position sensing. The hard-anodized aluminium body and S45C hard-chrome rod ensure long service life.
