About the Airtac ATE Single Acting Guided Compact Cylinder ATE63X25SB
This AirTAC ATE63X25SB is a single acting pull cylinder, spring-extend type, with a 63 mm bore and 25 mm stroke. It delivers a net pull of 1320 N at 0.5 MPa and 1903.2 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa. The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable space in tight machine frames and guarding. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper at both ends absorbs end-of-stroke impact.
With the optional -S magnet fitted, this model works with CMSE or DMSE sensors for position detection. For a safe vertical lift, plan for about 80 kg at 0.5 MPa (1320 N divided by 9.81, then halved for a 2:1 margin), which helps you match real part weights. The male rod thread (B code) simplifies mounting with rod-end accessories, and the 1/8" port suits standard pneumatic fittings.

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 ATE63X25SB Is Used
Jig Clamping Pull
In a CNC machining cell, this cylinder pulls a clamp arm to secure a workpiece during drilling. The 1320 N pull at 0.5 MPa holds parts firmly, and the short body fits between spindle and fixture.
Conveyor Stop Gate
On a packaging line, this cylinder retracts a stop gate to release boxes onto a conveyor. The spring extends the gate when air is off, ensuring a default closed position, and the 25 mm stroke is enough for small cartons.
Assembly Press Retract
In an automated assembly station, this cylinder pulls a pressing die back after a part is inserted. The 1903.2 N pull at 0.7 MPa clears the die quickly, and the TPU bumper reduces shock at the end of stroke.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE63X25SB the Right Cylinder?
Choose this 63 mm bore for applications needing a reliable pull force around 1320 N at 0.5 MPa. If your load is lighter, a 50 mm bore pulls 775 N at 0.5 MPa, while a larger 80 mm bore offers 2159.1 N at the same pressure. Remember, the spring extends the rod at rest, and air retracts it, so it does not hold a mid-stroke position on air loss. The compact ISO 21287 face accepts FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, plus I/Y rod knuckles, for flexible mounting. The optional -S magnet enables CMSE or DMSE switches for position feedback.
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 ATE63X25SB FAQ
The ATE63X25SB delivers a net pull of 1320 N at 0.5 MPa and 1903.2 N at 0.7 MPa, with the spring force already subtracted. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi). Operating pressure range is 0.2-1.0 MPa (28-145 psi).
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight spaces like gantries or guard panels. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the optional -S magnet allows CMSE or DMSE sensors for position feedback.
