Airtac ATE Single Acting Guided Compact Cylinder ATE63X20B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE63X20B 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 ATE63X20B
This AirTAC ATE63X20B 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 pulling tasks in compact spaces.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, letting it fit into tight gantries and machine guards. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and with a 1320 N pull you can plan for a safe working load of about 792 N, or roughly 81 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 ATE63X20B Is Used
Fixture Clamping
Use the 1320 N pull to retract a clamping arm on a CNC fixture, holding parts firmly during drilling or milling cycles in a compact machine cell.
Gate Retraction
Retract a stop gate on a packaging conveyor to release products, with the spring extending the gate back into place when air is removed.
Press Tray Pull
Pull a tray or slide out of a small press for part loading, using the 1903.2 N at 0.7 MPa to overcome friction and return the tray with the spring.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE63X20B the Right Cylinder?
For a lighter pull, consider the ATE50X25 with 775 N at 0.5 MPa, while the ATE80X25 offers 2159.1 N if you need more force. This ATE63X20B has a male rod thread (B code) and a 1/8" port, and its 20 mm stroke is within the standard 25 mm limit. On air loss the spring returns the rod to its extended position, so it does not hold a mid-stroke load.
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 ATE63X20B FAQ
The ATE63X20B delivers a net pull of 1320 N at 0.5 MPa and 1903.2 N at 0.7 MPa, with forces already accounting for the return spring. Minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
No, this model has no magnet because the -S code was not ordered. To use CMSE or DMSE switches, you must order the ATE63X20BS version with the optional magnet. The fixed TPU bumper at both ends handles end-of-stroke impact without adjustment.
