About the Airtac ATE Single Acting Guided Compact Cylinder ATE50X25SB
This AirTAC ATE50X25SB 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 775 N of pull force net of the spring, and at 0.7 MPa it reaches 1127.5 N, so it suits light clamping or lifting tasks in tight spaces.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for cramped jigs and gantries. With the optional -S magnet fitted, you can mount CMSE or DMSE switches for position sensing. For a safe vertical lift, plan for about 47 kg (0.6 x 775 N divided by 9.81) to keep 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 (Ø50mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 775.0 N |
| 0.7 MPa | 1127.5 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 ATE50X25SB Is Used
Jig Clamping
Use the 775 N pull to retract a clamp arm in a CNC fixture, holding parts securely during drilling or milling in a compact work envelope.
Gate Lifting
In a packaging line, this cylinder can lift a small safety gate or guard panel about 47 kg vertically with a 2:1 safety margin, retracting on air signal.
Parts Ejection
Mount it to pull a pin or ejector rod that releases stamped parts from a die, using the spring extend to reset the mechanism after each cycle.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE50X25SB the Right Cylinder?
Choose this 50 mm bore model when you need a pull force of 775 N at 0.5 MPa in a short-stroke application. For lighter duties, the 40 mm bore offers 500.3 N, while stepping up to 63 mm gives 1320 N at the same pressure. The spring returns the rod to its extended position on air loss, but it does not hold a mid-stroke load. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, plus I and Y rod knuckles.
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 ATE50X25SB FAQ
At 0.5 MPa, the pull force is 775 N net of the spring. At 0.7 MPa, it increases to 1127.5 N. The minimum working pressure is 0.2 MPa, and the maximum is 1.0 MPa (28-145 psi). The proof pressure is 1.5 MPa (215 psi).
The ATE50X25SB has a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, saving valuable space in tight fixtures. It includes a fixed TPU bumper at both ends to absorb end-of-stroke energy, and the optional -S magnet allows CMSE or DMSE sensors to detect rod position.
