About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X20B
This 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 1420.5 N of push force net of the spring, and at 0.7 MPa it reaches 2044 N, making it a strong choice for compact automation tasks.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight jigs and guarded cells where a full-length cylinder would not. For a safe working load, plan for about 852 N of real work at 0.5 MPa, which is roughly 87 kg of vertical lift with a 2:1 safety margin, so you can match it to actual part weights.

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 (Ø63mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 1420.5 N |
| 0.7 MPa | 2044.0 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 ASE63X20B Is Used
Jig Clamping on CNC Fixtures
Use the ASE63X20B to clamp small parts in a CNC fixture where the short body fits under a guard. The 1420.5 N push at 0.5 MPa holds a workpiece firmly, and the spring returns the clamp when air is released.
Carton Tabbing in Packaging Lines
In a carton erecting machine, this cylinder pushes a tab into place with a 20 mm stroke. The compact build fits between conveyor rails, and the spring return resets the tabber for the next cycle at speeds up to 500 mm/s.
Parts Ejection from Press Dies
Mount the ASE63X20B behind a press die to eject a stamped part after forming. The 20 mm stroke clears the part, and the 1420.5 N force at 0.5 MPa is enough to push out even slightly stuck pieces, with the spring pulling the rod back.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X20B the Right Cylinder?
If you need less force, the ASE50 with 875.5 N push at 0.5 MPa is a lighter option, while the ASE80 at 2316.2 N push at 0.5 MPa offers more headroom for heavier loads. 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 position; use it for simple extend-and-return tasks. The male rod thread (B code) simplifies mounting with rod end accessories, and the 1/8" port matches standard fittings for this bore size.
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 ASE63X20B FAQ
The ASE63X20B delivers 1420.5 N push at 0.5 MPa and 2044 N push at 0.7 MPa, both net of the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi). Operating pressure range is 0.2-1.0 MPa (28-145 psi).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight jigs and guards. It uses a fixed TPU bumper at both ends to absorb end-of-stroke energy, and the hard-anodized aluminium body with S45C hard-chrome rod ensures durability. This model has no magnet, so order the -S code if you need CMSE or DMSE sensors.
