Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X25B
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X25B is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø63mm bore and 25mm 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 ASE63X25B
This ASE63X25B is a single acting push cylinder with spring return, meaning air extends the rod and the internal spring pulls it back when pressure drops. It delivers 1420.5 N of push force at 0.5 MPa, already net of the return spring, so you can size it directly against your load without subtracting spring resistance.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which lets it fit into tight machine guarding and compact jigs. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, and the fixed TPU bumper at both ends absorbs end-of-stroke impact. For a safe working load, plan for about 852 N (roughly 87 kg) of real work at 0.5 MPa, not the full rated force.

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 ASE63X25B Is Used
Fixture Clamping
Use this cylinder to clamp a workpiece in a CNC fixture. The 1420.5 N push at 0.5 MPa holds parts firmly during machining, and the spring return lifts the clamp when the air is released.
Conveyor Stop Gate
Mount this cylinder on a packaging line to raise a stop gate that diverts boxes. The 25 mm stroke moves the gate quickly, and the spring retract clears the path when pressure drops.
Press Ram Guard
In a small press, this cylinder can actuate a safety guard that shields the die area. The compact body fits under the press frame, and the TPU bumper softens the impact at the end of each stroke.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X25B the Right Cylinder?
When choosing between bores, compare the 50 mm bore at 875.5 N and the 80 mm bore at 2316.2 N at 0.5 MPa. This 63 mm version sits in the middle, offering a strong push for medium-duty applications. The male rod thread (B code) simplifies mounting with rod-end accessories, and the 1/8" port suits standard shop air lines. Since this model has no -S code, there is no magnet fitted, so CMSE or DMSE sensors cannot be used unless you order the optional -S version.
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 ASE63X25B FAQ
At 0.5 MPa, the push force is 1420.5 N, and at 0.7 MPa it is 2044 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 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into machine guarding, gantries, and fixtures where a full-length cylinder would not. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the hard-anodized aluminium body resists wear. This model has a male rod thread and a 1/8" port.
