About the Airtac ATE Single Acting Guided Compact Cylinder ATE63X20S
This AirTAC ATE63X20S is a single acting pull cylinder with spring return, so the spring extends the rod and air retracts it. It delivers 1320 N of pull at 0.5 MPa, net of the return spring, and 1903.2 N at 0.7 MPa.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting tight gantries and guards. With the optional -S magnet fitted, CMSE or DMSE switches can be mounted for position sensing, and the fixed TPU bumper absorbs end-of-stroke impact. For a safe working load, plan for about 792 N (0.6 x 1320 N) of real work at 0.5 MPa, or about 80 kg vertically with a 2:1 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 (Ø63mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 1320.0 N |
| 0.7 MPa | 1903.2 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 ATE63X20S Is Used
Jig Clamping Pull
Use in a CNC fixture to retract a clamp pin that holds a machined part during drilling, with 1320 N pull at 0.5 MPa to secure the workpiece.
Carton Tucking
In a packaging line, retract a tucker blade to fold carton flaps before sealing, leveraging the short stroke and compact body to fit under the conveyor.
Gate Latch Release
On an automated safety gate, pull a latch pin to release a door, with the spring extending the pin to lock when air is off, ensuring fail-safe closure.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE63X20S the Right Cylinder?
For a smaller pull force, consider the ATE50X25S with 775 N at 0.5 MPa, or step up to the ATE80X25S for 2159.1 N. This 63 mm bore model suits short-stroke pull applications up to 25 mm standard, with a 20 mm stroke here. The spring returns the rod to extended on air loss, but it does not hold a mid-stroke position, so use mechanical stops for precise positioning. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, with the optional magnet enabling CMSE/DMSE sensors.
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 ATE63X20S FAQ
The ATE63X20S delivers 1320 N pull at 0.5 MPa and 1903.2 N at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, and proof pressure is 1.5 MPa (215 psi).
Yes, this model has the optional -S magnet fitted, so you can mount CMSE or DMSE reed or solid-state switches. The compact ISO 21287 body has magnet slots around it for easy switch positioning, and the fixed TPU bumper handles end-of-stroke deceleration.
