Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X5B
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X5B is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø63mm 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 ASE63X5B
The ASE63X5B is a single acting push cylinder with spring return, extending its 16 mm rod on air pressure and retracting it with the built-in spring. It delivers 1420.5 N of push force at 0.5 MPa (net of the spring), which suits medium-duty clamping and positioning in automated assembly lines.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine guards and gantries. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper absorbs end-of-stroke impact. With a 1/8" port and a male rod thread, it is ready for direct mounting in standard fixtures. For a safe working load, plan for about 852 N (0.6 times the 0.5 MPa rating) to leave a margin for real-world friction and side loads.

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 ASE63X5B Is Used
Fixture Clamping
Use in a CNC machine fixture to clamp small parts with 1420.5 N at 0.5 MPa, holding them securely during drilling or milling operations.
Carton Tabbing
In a packaging line, the 5 mm stroke pushes a tab or flap into place on cardboard boxes, with the spring returning the rod quickly for the next cycle.
Valve Actuation
Actuate a small pneumatic valve or gate in a process line, where the compact body fits into a control panel and the spring ensures fail-safe retraction on air loss.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X5B the Right Cylinder?
For a lighter application, the ASE50X5 offers 875.5 N at 0.5 MPa, while the ASE80X5 provides 2316.2 N if you need more force. The 5 mm stroke is short, so it suits quick, small movements rather than long travel. This model has a male rod thread (B code) and no magnet, so it cannot accept CMSE or DMSE sensors unless you order the -S option. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, which bolt directly to the ISO 21287 face.
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 ASE63X5B FAQ
At 0.5 MPa, the push force is 1420.5 N; at 0.7 MPa, it is 2044 N. These are net of the return spring, so they are the usable forces. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
No, this model has no magnet because it lacks the -S code. To use CMSE or DMSE reed or solid-state switches, you must order the ASE63X5SB version with the optional magnet. The fixed TPU bumper at both ends handles end-of-stroke impact, but it is not adjustable.
