Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X5B
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X5B is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø50mm bore and 5mm 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 ASE50X5B
This AirTAC ASE50X5B is a single acting, spring-return compact cylinder that extends its 16 mm rod with air and retracts it with a built-in spring. It delivers a net push of 875.5 N at 0.5 MPa, so it suits light pressing or clamping tasks where a powered return is not needed.
Its ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, fitting into tight machine guards and gantries. With a 5 mm stroke, it is ideal for precise, short movements, and the fixed TPU bumper absorbs end-of-stroke energy. For real work, plan for about 525 N (0.6 x 875.5 N) to keep a safety margin, which equals lifting about 54 kg vertically with 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 | 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 ASE50X5B Is Used
Jig Clamping
Use the 875.5 N push at 0.5 MPa to clamp small parts in a drill jig. The 5 mm stroke is enough to secure a workpiece, and the spring retracts the rod automatically when air is released.
Label Applicator
In a packaging line, this cylinder can press a label onto a box with a short, controlled stroke. The compact body fits under a conveyor guard, and the fixed TPU bumper prevents harsh impacts at high cycle rates.
Valve Actuator
For a small pneumatic valve that needs a quick, single-action push, this ASE50X5B provides reliable force. The male rod thread simplifies linkage, and the 1/8" port connects easily to standard air lines.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X5B the Right Cylinder?
Choose this ASE50X5B when you need a compact, single-acting push with a short 5 mm stroke and a male rod thread. Compare it with the smaller ASE32X25, which offers 352.5 N at 0.5 MPa, or the larger ASE63X25 with 1420.5 N, to match your force needs. The spring returns the rod to its home position on air loss, but it does not hold a mid-stroke load. Since this model has no -S code, it lacks the optional magnet, so CMSE or DMSE sensors cannot be mounted without ordering a magnet-equipped version.
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 ASE50X5B FAQ
At 0.5 MPa, the push force is 875.5 N, and at 0.7 MPa it is 1268.2 N. These values are net of the return spring, so they are the usable forces. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
No, this ASE50X5B does not have the optional -S magnet, so it cannot work with CMSE or DMSE switches. If you need position sensing, order a model with the -S code. The cylinder has a fixed TPU bumper at both ends to absorb impact, and its compact ISO 21277 body saves space compared to a profile cylinder.
