Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15B
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15B 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.

About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15B
This AirTAC ASE50X15B is a single acting push cylinder with spring return, so air extends the rod and the built-in spring pulls it back when pressure drops. It delivers a net push force of 875.5 N at 0.5 MPa, which is already reduced by the spring, and needs a minimum of 0.2 MPa to overcome that spring and move the rod.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, letting it fit into tight machine frames and guarding where a longer cylinder will not go. With a 15 mm stroke, it suits short, repetitive pushes, and the fixed TPU bumper at each end absorbs impact without any adjustment. For real work, plan for about 525 N at 0.5 MPa, which is roughly 54 kg of vertical lift with a 2:1 safety margin, so you can match it to a part weight directly.

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 ASE50X15B Is Used
Jig Clamping
Use the 875.5 N push at 0.5 MPa to clamp a small part in a drill jig, where the spring return lifts the clamp clear for part changes. The short body fits under a worktable where a longer cylinder would interfere.
Carton Ejector
In a packaging line, this cylinder can push a filled carton off a conveyor onto a chute. The 15 mm stroke is enough to nudge the carton, and the spring retracts the rod quickly for the next cycle.
Guard Door Latch
Mount this cylinder to release a safety guard latch on a small press. Air extends the rod to unlock the door, and the spring returns it to the locked position when air is removed, keeping the guard closed by default.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15B the Right Cylinder?
When sizing, compare this 50 mm bore to the 40 mm bore, which pushes 556.8 N at 0.5 MPa, or the 63 mm bore at 1420.5 N, to see if you need more or less force. The 15 mm stroke is well within the 25 mm maximum standard for this bore, so it is a standard off-the-shelf unit. Since this model has no -S code, there is no magnet fitted, so CMSE or DMSE sensors cannot be mounted; order the -S version if you need position sensing. The male rod thread (B) simplifies direct coupling to a load without a female rod adapter.
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 ASE50X15B FAQ
The net push force is 875.5 N at 0.5 MPa and 1268.2 N at 0.7 MPa, both after subtracting the return spring force. 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), with a speed range of 50-500 mm/s.
It is an ISO 21287 compact cylinder, so its body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight fixtures. The fixed TPU bumper at both ends absorbs end-of-stroke impact. This model has no magnet, so CMSE or DMSE switches cannot be used; you would need the -S option to add the magnet for sensor feedback.
