Airtac ATE Single Acting Guided Compact Cylinder ATE80X20SB
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE80X20SB 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 ATE80X20SB
This AirTAC ATE80X20SB is a single acting pull cylinder with a spring return, so the spring extends the rod and air retracts it. With an 80 mm bore, it delivers a net pull of 2159.1 N at 0.5 MPa, enough to handle substantial retraction tasks in tight spaces.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable mounting length in crowded machinery. The optional -S magnet is fitted here, enabling CMSE or DMSE sensors for position detection. For a real-world load, plan for about 132 kg of vertical lift (2159.1 N divided by 9.81, then halved for a 2:1 safety margin).

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 (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 ATE80X20SB Is Used
Jig Retraction
Use in a CNC fixture to retract a locating pin or clamp after machining. The 20 mm stroke and 2159.1 N pull at 0.5 MPa handle the release quickly, while the compact body fits under the worktable.
Sorting Gate Pull
In a parcel sorting conveyor, this cylinder pulls a diverter gate back to redirect packages. The spring extends the gate to its default position when air is off, ensuring fail-safe operation.
Packaging Machine Tensioner
Retract a film tension roller on a packaging line. The 80 mm bore provides ample force to overcome roller inertia, and the fixed TPU bumper absorbs end-of-stroke impact for smooth cycling.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE80X20SB the Right Cylinder?
Choose this 80 mm bore model when you need a strong pull force in a short envelope; it provides 2159.1 N at 0.5 MPa. For lighter duties, the 63 mm bore offers 1320.0 N, while the 100 mm bore steps up to 3483.6 N at the same pressure. Remember, the spring returns the rod to its extended home 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 ATE80X20SB FAQ
At 0.5 MPa, the net pull force is 2159.1 N. At 0.7 MPa, it increases to 3101.6 N. These forces are net of the return spring, so they represent the actual retraction capability. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, making it ideal for tight fixtures. The fixed TPU bumper at both ends absorbs energy, and the optional -S magnet allows CMSE or DMSE sensors for position feedback. The rod end is male thread (M12x1.75) with a 1/4" port.
