Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X20
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X20 is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø50mm bore and 20mm 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 ASE50X20
This AirTAC ASE50X20 is a single acting push cylinder with spring return, so air extends the rod and the spring retracts it. 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 the spring.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, fitting into tight jigs and guards. For a safe working load, plan for about 525 N of real work at 0.5 MPa, which lifts about 53 kg vertically with a 2:1 margin. The fixed TPU bumper absorbs end-of-stroke energy, and the hard-anodized aluminium body with S45C hard-chrome rod resists wear.

Where the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X20 Is Used
Jig Clamping
Use in a CNC fixture to clamp a small part with a 875.5 N push at 0.5 MPa, and the spring retracts the clamp for quick part changes.
Label Applicator
Drive a label press head in a packaging line, where the compact body fits under a guard and the spring return lifts the head after each cycle.
Gate Stop
Act as a stop pin on a conveyor, extending to block a tote and retracting via spring when the line clears, saving space in a gantry system.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X20 the Right Cylinder?
For a lighter duty, the ASE40X25 offers 556.8 N at 0.5 MPa, while the ASE63X25 provides 1420.5 N for heavier tasks. This 50 mm bore with a 20 mm stroke is a compact option for short-stroke applications. Note that the spring returns the rod to its home position on air loss, so 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, with an optional -S magnet for 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 ASE50X20 FAQ
The ASE50X20 provides 875.5 N push at 0.5 MPa and 1268.2 N push at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, and proof pressure is 1.5 MPa (215 psi).
This model has no magnet, so CMSE or DMSE sensors cannot be mounted. To use sensors, order the ASE50X20S with the optional -S magnet. The compact ISO 21287 body has slots for the sensors, and the fixed TPU bumper handles end-of-stroke impact.
