Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X25S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X25S is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø50mm bore and 25mm 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 ASE50X25S
This AirTAC ASE50X25S is a single acting push cylinder with spring return, so air extends the rod and the return spring retracts it. It delivers 875.5 N of push force at 0.5 MPa, already net of the spring, and needs a minimum of 0.2 MPa to overcome that spring.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, fitting into tight jigs and guards. With the optional -S magnet fitted here, you can mount CMSE or DMSE reed or solid-state switches for position sensing. For a safe working load, plan on about 525 N of real work at 0.5 MPa, which lifts roughly 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 ASE50X25S Is Used
Compact Jig Clamping
Use the ASE50X25S to clamp small parts in a CNC fixture where the short ISO 21287 body fits under a guard, delivering 875.5 N to hold the workpiece during a drilling cycle.
Carton Ejection
On a packaging line, this cylinder can push a filled carton off a conveyor onto a chute. The 25 mm stroke and 875.5 N force are enough to move a 10 kg box, and the spring retracts the rod for the next cycle.
Gate Stop on a Palletizer
Mount the ASE50X25S as a retractable stop on a palletizing conveyor. The 50 mm bore provides 875.5 N to hold back a pallet, and the compact body allows mounting in a confined space between rollers.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X25S the Right Cylinder?
For a lighter duty, the 40 mm bore ASE40X25 gives 556.8 N at 0.5 MPa, while the 63 mm bore ASE63X25 provides 1420.5 N. Since this is single acting, the spring returns the rod to its home position on air loss, so it does not hold a mid-stroke load. The 1/8" port and M10x1.5 female rod thread match standard fittings, and the optional -S magnet is already included for sensor feedback.
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 ASE50X25S FAQ
The ASE50X25S delivers 875.5 N of push force at 0.5 MPa and 1268.2 N at 0.7 MPa, both net of the return spring. It operates from 0.2-1.0 MPa (28-145 psi), with a proof pressure of 1.5 MPa (215 psi).
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into machine guards and jigs where a longer cylinder would not. It has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows CMSE or DMSE sensors for position feedback.
