About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X25SB
This AirTAC ASE50X25SB is a single acting push, spring-return compact cylinder built to ISO 21287, with a 50 mm bore and 25 mm stroke. It delivers a net push force of 875.5 N at 0.5 MPa, already accounting for the return spring, and the hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable space in tight fixtures.
For a safe working load at 0.5 MPa, plan for about 525 N of real work, which translates to lifting roughly 54 kg vertically with a 2:1 safety margin. The male rod thread (B code) and the fitted optional -S magnet for CMSE or DMSE switches make it ready for position sensing, while the fixed TPU bumper at both ends absorbs end-of-stroke energy.

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 | Push force (spring return) |
|---|---|
| 0.5 MPa | 875.5 N |
| 0.7 MPa | 1268.2 N |
Single-acting push: air extends the rod; the return spring 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 ASE Single Acting Plunger Type Compact Air Cylinder ASE50X25SB Is Used
Jig Clamping
Use the 875.5 N push at 0.5 MPa to clamp a workpiece in a CNC milling fixture, where the compact body fits under a guard and the spring retract clears the part automatically.
Carton Ejection
In a packaging line, this cylinder pushes a finished carton off a conveyor onto a chute, with the 25 mm stroke providing enough travel and the spring return resetting for the next cycle.
Gate Actuator
Actuate a small safety gate on a machine guard, where the short ISO 21287 body saves about 50% of the mounting length compared to a profile cylinder, and the spring retract keeps the gate closed when air is off.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X25SB the Right Cylinder?
When sizing, compare this 50 mm bore with a 40 mm bore that pushes 556.8 N at 0.5 MPa, or a 63 mm bore that pushes 1420.5 N. The 50 mm bore suits medium-duty applications where the 40 mm is underpowered but the 63 mm is oversized. Remember this is single acting, so the spring retracts the rod and it does not hold a mid-stroke position on air loss. The optional -S magnet is fitted here, so you can mount CMSE or DMSE sensors 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 ASE Single Acting Plunger Type Compact Air Cylinder ASE50X25SB FAQ
The ASE50X25SB delivers a net push force of 875.5 N at 0.5 MPa and 1268.2 N at 0.7 MPa, with these values already accounting for the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight spaces like machine guards or gantries. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE switches for position sensing.
