The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE63X10S is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø63mm bore and 10mm 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 ASE63X10S is a single acting push cylinder from AirTAC, meaning air extends the rod and a built-in spring retracts it, so it needs only one air line and returns home on air loss. With a 63 mm bore, it delivers 1420.5 N of push force at 0.5 MPa, already net of the spring, and 2044 N at 0.7 MPa.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while fixed TPU bumpers at both ends absorb end-of-stroke impact. As a rule of thumb, plan for about 852 N of safe working load at 0.5 MPa, which equals lifting roughly 87 kg vertically with a 2:1 safety 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.
In a CNC machining cell, this ASE63X10S can clamp a small fixture plate with 1420.5 N at 0.5 MPa, holding parts securely during drilling. Its short body fits under the worktable, and the spring retracts the clamp when air is released for quick part changes.
On a packaging line, use this cylinder to push a glue tab into place on a carton flap. The 10 mm stroke is enough for the tab, and the 63 mm bore provides the force to press it firmly, while the spring returns the pusher for the next cycle.
In a press brake enclosure, this cylinder can extend a locking pin into a guard door frame with over 1400 N of force, ensuring the door stays closed during operation. The compact body mounts easily beside the hinge, and the spring retracts the pin when the guard is released.
For a lighter duty, consider the ASE50X10 with 875.5 N push at 0.5 MPa, or step up to the ASE80X10 for 2316.2 N if you need more force. This 63 mm bore model suits short-stroke applications up to 25 mm standard, and the 10 mm stroke here is well within that. Since the spring retracts the rod, it does not hold a mid-stroke position on air loss, so use it for simple extend-and-return tasks. The -S code means the magnet is fitted, so you can mount CMSE or DMSE reed or solid-state switches for position sensing, and the 1/8" port connects directly to standard pneumatic fittings.
Quick checklist
The ASE63X10S delivers 1420.5 N of push force at 0.5 MPa and 2044 N at 0.7 MPa, both net of the return spring. The minimum working pressure is 0.2 MPa, and the maximum is 1.0 MPa (28-145 psi). At 0.5 MPa, a safe working load is about 852 N, which translates to lifting roughly 87 kg vertically with a 2:1 safety margin.
The ISO 21277 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits in tight spaces like under guards or inside gantries. The hard-anodized aluminium body and S45C hard-chrome rod are durable, and the fixed TPU bumpers absorb end-of-stroke impact without adjustment. The -S magnet allows CMSE or DMSE sensors to detect rod position.
