Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X25S
The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X25S 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 ASE63X25S
This AirTAC ASE63X25S is a single acting push cylinder with spring return, delivering a net push force of 1420.5 N at 0.5 MPa and 2044 N at 0.7 MPa. Its compact ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, fitting into tight machine guards and gantries where a full-length cylinder would not. The optional -S magnet is fitted here, enabling CMSE or DMSE reed and solid-state switches for position sensing.
For a safe working load at 0.5 MPa, plan for about 853 N of real work, not the full rating. This translates to a vertical-lift equivalent of roughly 87 kg with a 2:1 safety margin, so you can match a real part weight with confidence. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper absorbs end-of-stroke energy without needing adjustment.

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 ASE63X25S Is Used
Jig Clamping
Use in a CNC fixture to clamp a 63 mm bore workpiece with 1420.5 N at 0.5 MPa, holding parts securely during drilling or milling operations.
Guard Door Interlock
Mount on a machine guard to push a safety latch into place, with the spring return ensuring the latch retracts when air is removed, fitting within a 25 mm stroke envelope.
Sorting Pusher
On a packaging line, push 25 mm to divert lightweight cartons onto a side conveyor, using the 1420.5 N force to handle boxes up to 87 kg safely with margin.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X25S the Right Cylinder?
When sizing, compare this 63 mm bore with the 50 mm bore, which pushes 875.5 N at 0.5 MPa, and the 80 mm bore, which pushes 2316.2 N at 0.5 MPa. Choose the 63 mm for medium-duty clamping or pressing tasks where 25 mm of stroke is sufficient. Remember, the spring retracts the rod on air loss, so it does not hold a mid-stroke position; it returns to home. For mounting, FA/FB flanges, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets bolt directly to the ISO 21287 face. The port is 1/8" PT, and the rod thread is M10x1.5 female.
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 ASE63X25S FAQ
At 0.5 MPa, the push force is 1420.5 N, and at 0.7 MPa it is 2044 N. These are net of the return spring. 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 in tight spaces. It has a fixed TPU bumper at both ends to absorb impact. The optional -S magnet is fitted on this model, allowing CMSE or DMSE switches to detect the piston position.
