About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X5SB
This AirTAC ASE50X5SB is a single acting push cylinder with spring return, meaning air extends the rod and the spring retracts it, requiring only one air line. With a 50 mm bore, it delivers 875.5 N of push force at 0.5 MPa (net of the spring), and 1268.2 N at 0.7 MPa, making it a strong choice for short-stroke tasks.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight spaces where a full-length cylinder won't. This model includes the optional -S magnet, so you can mount CMSE or DMSE switches for position sensing. For a safe working load, plan for roughly 525 N of real work at 0.5 MPa, which translates to lifting about 54 kg vertically with a 2:1 margin.

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 ASE50X5SB Is Used
Fixture Clamping
Use in a jig to clamp small parts during drilling or milling. The 875.5 N force at 0.5 MPa holds components firmly, and the compact body fits under machine guards.
Label Applicator
Drive a label applicator head in a packaging line. The 5 mm stroke provides quick, repeatable extension to press labels onto boxes, with the spring return resetting for the next cycle.
Ejector Pin
Act as an ejector pin in a small assembly fixture. The short stroke pushes a pin to release a molded part, and the TPU bumper absorbs the end-of-stroke impact, protecting the part.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X5SB the Right Cylinder?
When sizing, consider that a 40 mm bore ASE delivers 556.8 N at 0.5 MPa, while this 50 mm bore gives 875.5 N, offering a significant boost for heavier loads. The 5 mm stroke is short, so it suits applications needing quick, precise movements rather than long travel. Since it is single acting, it does not hold a mid-stroke position on air loss; the spring returns the rod home. The male rod thread (B code) simplifies mounting, and the 1/8" port matches standard fittings.
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 ASE50X5SB 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 actual force available to move a load. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable space in tight machine layouts. It also has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows CMSE or DMSE switches for position sensing.
