Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X20SB
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X20SB is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø63mm 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 ASE63X20SB
This AirTAC ASE63X20SB is a single acting push cylinder with spring return, so air extends the rod and a built-in spring retracts it. It needs only one air line and rests retracted when pressure is off, with a minimum working pressure of 0.2 MPa to overcome the spring.
At 0.5 MPa the net push force is 1420.5 N, rising to 2044 N at 0.7 MPa. The compact ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, which helps fit tight guards and gantries. With the -S magnet fitted, you can mount CMSE or DMSE reed or solid-state switches for position sensing. As a rule of thumb, 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.

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 ASE63X20SB Is Used
Jig Clamping
Use the 1420.5 N push at 0.5 MPa to clamp sheet metal parts in a welding jig, with the spring retracting the rod for quick part removal.
Sorting Gate
Divert small boxes on a packaging line by extending a 20 mm stroke pusher; the compact body fits under a conveyor guard.
Fixture Ejector
Eject a finished machined part from a CNC fixture with a short 20 mm push, relying on the spring to return the rod before the next cycle.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X20SB the Right Cylinder?
For a lighter duty, the 50 mm bore ASE50X25 delivers 875.5 N at 0.5 MPa, while stepping up to the 80 mm bore ASE80X25 gives 2316.2 N. The 20 mm stroke suits short indexing or clamping moves, and the spring return means the rod retracts on air loss, but it does not hold a mid-stroke position. Choose the FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC bracket to match your fixture, and the male rod thread (B) simplifies coupling to a load.
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 ASE63X20SB FAQ
At 0.5 MPa the push force is 1420.5 N, and at 0.7 MPa it is 2044 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).
No, the magnet is an optional -S code, and this model carries it, so you can mount CMSE or DMSE switches. Without the -S code, there is no magnet. The body is a compact ISO 21287 design with a fixed TPU bumper at both ends, not an adjustable cushion.
