Airtac ATE Single Acting Guided Compact Cylinder ATE63X20
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE63X20 is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø63mm bore and 20mm stroke, 1/8" 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 ATE63X20
This AirTAC ATE63X20 is a single acting pull cylinder with spring return, meaning the spring extends the rod and air retracts it. At 0.5 MPa it delivers a net pull of 1320 N, and at 0.7 MPa that rises to 1903.2 N, so it suits moderate force applications in a compact envelope.
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, which helps fit into tight machine guards and gantries. The optional -S magnet enables CMSE or DMSE sensors, and with a 2:1 safety margin this model can lift about 67 kg vertically at 0.5 MPa, making it a practical choice for lifting light subassemblies.

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 ATE63X20 Is Used
Jig Clamping
Use the ATE63X20 to pull a clamp arm onto a workpiece in a CNC fixture. The 1320 N pull at 0.5 MPa holds parts securely, and the compact body fits under a machine guard.
Gate Positioning
Mount this cylinder on a packaging conveyor to retract a stop gate. The spring extends the gate to block products, and air pulls it down to let items pass, with a 20 mm stroke ideal for thin packages.
Light Assembly Lift
In an electronics assembly line, use the ATE63X20 to pull a small platform down after a component is placed. With a safe vertical lift of about 67 kg, it handles typical subassemblies without overloading.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE63X20 the Right Cylinder?
For a smaller option, the ATE50X25 provides 775 N pull at 0.5 MPa, while the ATE80X20 (if needed) offers 2159.1 N. Since this is a single acting pull cylinder, it returns to the extended position on air loss and does not hold a mid-stroke load. Choose the -S code if you need the magnet for position sensing, and select from FA, FB, LB, CA, CB, CR, SDB, or FTC mountings to match your fixture.
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 ATE63X20 FAQ
At 0.5 MPa the net pull is 1320 N, and at 0.7 MPa it is 1903.2 N. These forces already account for the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
No, the magnet is optional. You must order the -S code (e.g., ATE63X20S) to get the built-in magnet for CMSE or DMSE sensors. Without the -S code, no sensor can be mounted. The fixed TPU bumper at both ends absorbs end-of-stroke impact.
