Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15SB
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15SB is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø50mm bore and 15mm 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 ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15SB
The ASE50X15SB is a single acting push cylinder with spring return, extending its 16 mm rod on air pressure and retracting it via the built-in spring. It delivers 875.5 N of push force at 0.5 MPa (net of the spring), so it suits moderate clamping and pressing tasks in tight spaces.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, fitting easily into confined jigs and guards. The optional -S magnet is fitted here, enabling CMSE or DMSE sensors for position detection. For real work, plan for about 525 N at 0.5 MPa, which translates to lifting roughly 54 kg vertically with a 2:1 safety 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 | 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 ASE50X15SB Is Used
Fixture Clamping
Use in a CNC fixture to clamp small parts with 875.5 N at 0.5 MPa, holding them securely during drilling or milling in a compact work envelope.
Carton Pressing
In packaging lines, this cylinder presses folded cartons flat with a spring return, saving space on a conveyor where full-length cylinders won't fit.
Guard Door Latch
Mount on a machine guard to push a latch closed, with the spring retracting it when air is off, ensuring safety in a tight enclosure.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15SB the Right Cylinder?
For lighter duty, the ASE40X25 offers 556.8 N at 0.5 MPa, while the ASE63X25 provides 1420.5 N for heavier loads. This 50 mm bore with a 15 mm stroke is a balanced choice for compact automation where space is limited. The spring retracts the rod on air loss, returning it to home, but it does not hold mid-stroke positions; use a separate brake if needed. Mounting options include FA/FB flanges, LB foot, CA/CB clevis, and SDB pivot brackets, all compatible with 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 ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15SB FAQ
At 0.5 MPa, the push force is 875.5 N, and at 0.7 MPa it is 1268.2 N, both net of the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The body is about 50% shorter than an ISO 15552 profile cylinder, saving mounting length in tight spots. It has a fixed TPU bumper at both ends to absorb impact, and the -S magnet allows CMSE or DMSE sensors for position feedback.
