About the Airtac ATE Single Acting Guided Compact Cylinder ATE63X25S
This AirTAC ATE63X25S 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 1320 N of pull force, net of the return spring, making it a reliable choice for compact automation.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight machine guards and gantries. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing. As a buyer insight, this model safely lifts about 80 kg vertically at 0.5 MPa with a 2:1 margin, based on the 1320 N rating.

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 ATE63X25S Is Used
Jig Clamping
Use the 1320 N pull to retract a clamping arm in a CNC fixture, holding a 63 mm bore workpiece securely during drilling operations.
Gate Divert
Mount on a packaging conveyor to pull a divert gate open, directing 25 mm stroke movements for boxes weighing up to 80 kg.
Press Guard
Retract a safety guard on a small stamping press, using the spring extend to close the guard automatically when air is removed.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE63X25S the Right Cylinder?
For lighter duty, the ATE50X25 offers 775 N pull at 0.5 MPa, while this ATE63X25S steps up to 1320 N for heavier parts. 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 fitting 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 ATE63X25S FAQ
The ATE63X25S delivers 1320 N pull at 0.5 MPa and 1903.2 N pull at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, with a proof pressure of 1.5 MPa (215 psi).
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight spaces. The fixed TPU bumper absorbs end-of-stroke energy, and the optional -S magnet allows CMSE or DMSE sensors for position feedback.
