Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X5S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X5S is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø50mm bore and 5mm 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 ASE50X5S
This AirTAC ASE50X5S is a single acting push cylinder with spring return, so air extends the rod and the built-in spring retracts it, needing only one air line. It delivers a net push force of 875.5 N at 0.5 MPa and 1268.2 N at 0.7 MPa, already accounting for the spring, with a minimum working pressure of 0.2 MPa.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, making it ideal for tight machine guards and compact jigs. Since this model carries the optional -S magnet, you can mount CMSE or DMSE reed or solid-state switches for position sensing, and the fixed TPU bumper at both ends quietly absorbs end-of-stroke energy.

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 ASE50X5S Is Used
Short-Stroke Clamping
Use the 875.5 N push at 0.5 MPa to clamp thin sheet metal parts in a stamping die, where the 5 mm stroke clears the workpiece and the compact body fits between die pillars.
Tight Guard Interlock
Mount this cylinder inside a machine guard to push a small latch or pin 5 mm, with the ISO 21287 short body saving space behind the guard panel and the spring retracting the pin on air loss.
High-Cycle Sorting Gate
In a packaging line, this cylinder can divert small cartons by extending a 5 mm stop paddle at up to 500 mm/s, using the -S magnet with a CMSE switch to confirm each cycle.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X5S the Right Cylinder?
For lighter work in the same compact format, the 40 mm bore ASE40X25 pushes 556.8 N at 0.5 MPa, while stepping up to the 63 mm bore ASE63X25 gives 1420.5 N at the same pressure. With a 5 mm stroke, this unit suits short indexing or clamping moves, but the spring only returns the rod to its home position and does not hold a mid-stroke load. Choose FA, FB, LB, CA, CB, CR, SDB, or FTC mounts to fit standard ISO 21287 fixtures, and order the -S version 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 ASE50X5S FAQ
The ASE50X5S delivers a net push force of 875.5 N at 0.5 MPa and 1268.2 N at 0.7 MPa, with the return spring force already subtracted. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The ISO 21277 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight jigs and guards where a full-length cylinder would not. The fixed TPU bumper at both ends absorbs impact, and the optional -S magnet allows CMSE or DMSE sensors for position feedback.
