About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X20SB
This AirTAC ASE50X20SB 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. At 0.5 MPa it delivers 875.5 N of push force net of the spring, and at 0.7 MPa that rises to 1268.2 N, with a minimum working pressure of 0.2 MPa to overcome the spring.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which lets it fit into tight jigs and guards where a full-length unit will not. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper at both ends absorbs end-of-stroke impact. For a safe working load, plan for about 525 N (around 54 kg vertically with a 2:1 margin) rather than the full 875.5 N rating.

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 ASE50X20SB Is Used
Jig Clamping
Use this cylinder to clamp small parts in a CNC fixture, where the 875.5 N push at 0.5 MPa holds components firmly and the spring retract clears the work area quickly.
Sorting Gate
Mount it on a packaging conveyor to divert lightweight boxes into a reject lane. The 20 mm stroke is enough to shift a flap, and the compact body fits under the belt frame.
Press Guard Interlock
In a small bench press, this cylinder can push a safety guard into position before the ram cycles. The spring return ensures the guard retracts when air is removed, and the TPU bumper softens the stop.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE50X20SB the Right Cylinder?
Choose this ASE50X20SB for a compact, spring-return push action in a 50 mm bore with a 20 mm stroke. If you need less force, the 40 mm bore offers 556.8 N at 0.5 MPa, while stepping up to the 63 mm bore gives 1420.5 N at the same pressure, so you can match the thrust to your application. The male rod thread (B code) simplifies mounting with rod-end accessories, and the optional -S magnet is fitted here, enabling CMSE or DMSE reed and solid-state switches for position sensing.
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 ASE50X20SB FAQ
At 0.5 MPa, the push force is 875.5 N, and at 0.7 MPa it is 1268.2 N, both net of the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits in tight spaces. It has a fixed TPU bumper at both ends for impact absorption, and the optional -S magnet (fitted here) allows CMSE or DMSE switches for position sensing.
