The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X15SB is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø63mm bore and 15mm 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.
This AirTAC ASE63X15SB is a single acting push cylinder with spring return, extending on air and retracting via the built-in spring. With a 63 mm bore, it delivers 1420.5 N of push force at 0.5 MPa (net of the spring), so it suits moderate clamping and pressing tasks.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight fixtures. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing. For a safe working load, plan for about 853 N of real work at 0.5 MPa, which lifts roughly 87 kg vertically with a 2:1 margin.

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.
| 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).

ACE-family variants: ACE (double acting), ASE / ATE (single acting push / pull), ACED (double rod), ACEJ (adjustable stroke), TACE / TACED (non-rotating twin-guide yoke). Mounting accessories: FA / FB flange, LB foot, CA / CB clevis, CR, SDB pivot, FTC; plus I and Y knuckles. Thread PT (blank) / G.
Use in a CNC fixture to clamp a workpiece with 1420.5 N force at 0.5 MPa, where the compact body fits under a guard.
Drive a light press to flatten cardboard boxes in a packaging line, leveraging the 15 mm stroke for quick cycles.
Actuate a safety gate stop on a conveyor, with the spring return ensuring the rod retracts when air is off.
Compare with the 50 mm bore ASE50X25, which pushes 875.5 N at 0.5 MPa, or step up to the 80 mm bore ASE80X25 for 2316.2 N. This 63 mm model offers a middle ground with a 15 mm stroke, ideal for short travel. Remember, the spring retracts the rod and does not hold a mid-stroke position, so use it for push-only actions. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, with the male rod thread (B) ready for direct coupling.
Quick checklist
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).
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into confined jigs or gantries. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the optional -S magnet allows CMSE or DMSE sensors for position feedback.
