Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15S 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 ASE50X15S
This AirTAC ASE50X15S 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 875.5 N of push force at 0.5 MPa (net of the return spring), and 1268.2 N at 0.7 MPa, making it a solid choice for moderate-force automation tasks.
Because it is built to ISO 21287, the compact body is about 50% shorter than an ISO 15552 profile cylinder, which helps it fit into tight machine frames and guarding. The optional -S magnet is fitted here, so you can attach CMSE or DMSE reed or solid-state switches for position sensing. For a safe working load, plan on about 525 N (roughly 54 kg) of real work at 0.5 MPa, not the full rated force, to leave a margin for speed and wear.

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 ASE50X15S Is Used
Jig Clamping
Use the ASE50X15S to clamp small parts in a CNC fixture, where the 15 mm stroke and 875.5 N push at 0.5 MPa hold a bracket securely during drilling, and the spring retracts the pin when the cycle ends.
Carton Tabbing
In a packaging line, this cylinder can push a glue tab or insert a divider into a carton, with the short stroke fitting between conveyor rails and the spring return clearing the path for the next box.
Guard Door Latch
Mount the ASE50X15S on a machine guard to push a latch bolt into a receiver, keeping the guard closed during operation; the spring retracts the bolt when air is removed, allowing the guard to open.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15S the Right Cylinder?
When sizing, compare this 50 mm bore with a smaller 40 mm bore that gives 556.8 N at 0.5 MPa, or a larger 63 mm bore that gives 1420.5 N at 0.5 MPa. The ASE50X15S suits applications needing a compact stroke of 15 mm with a moderate push force. Remember, the spring returns the rod to its retracted position on air loss, so it does not hold a mid-stroke position. The 1/8" port is standard for this bore, and you can choose FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC mounting brackets to match your fixture.
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 ASE50X15S 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 represent the usable force available to extend the rod. The minimum working pressure is 0.2 MPa, and the maximum is 1.0 MPa.
The body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into confined areas like inside a machine guard or between conveyor sections. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE sensors to detect rod position.
