Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15 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 ASE50X15
This AirTAC ASE50X15 is a single acting push cylinder with spring return, so air extends the rod and the built-in spring pulls it back. It delivers 875.5 N of push force at 0.5 MPa, already net of the return spring, and needs a minimum of 0.2 MPa to overcome that spring.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, letting it fit into tight machine guards and gantries. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while fixed TPU bumpers at both ends soften the stop. For a 2:1 safety margin, plan to lift about 27 kg vertically with this unit at 0.5 MPa, not the full 875.5 N rating.

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 ASE50X15 Is Used
Fixture Clamping
Use in a jig to clamp a small aluminium bracket during drilling. The 875.5 N force at 0.5 MPa holds the part firmly, and the spring retracts the rod automatically when air is released, speeding up part changeover.
Carton Tabbing
In a packaging line, this cylinder pushes a folded carton flap into place before sealing. The short 15 mm stroke matches the flap depth, and the compact body fits between existing conveyor rails without extra framing.
Guard Door Latch
Mount on a machine guard to push a latch pin into a receiver. The spring returns the pin to the unlocked position when air is off, providing a fail-safe that lets the guard open for maintenance.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X15 the Right Cylinder?
When sizing, compare this 50 mm bore with the 40 mm bore, which pushes 556.8 N at 0.5 MPa, or step up to the 63 mm bore for 1420.5 N at the same pressure. The 15 mm stroke suits short indexing moves, and the spring returns the rod to its home position on air loss, but it does not hold a mid-stroke position. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all matching the ISO 21287 face. This model has no magnet, so order the optional -S code if you need to fit CMSE or DMSE sensors.
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 ASE50X15 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). The operating pressure range is 0.2-1.0 MPa (28-145 psi).
Yes, it is an ISO 21287 compact cylinder, with a body about 50% shorter than an ISO 15552 profile cylinder. It has fixed TPU bumpers at both ends for end-of-stroke deceleration. This model has no magnet, so you cannot mount sensors unless you order the optional -S code, which adds a magnet for CMSE or DMSE switches.
