The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X10 is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø100mm bore and 10mm stroke, 1/4" 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.
A single acting push cylinder with spring return, the ASE100X10 uses air to extend its 20 mm rod and the internal spring to pull it back home - so one air line does the whole job and the rod sits retracted whenever pressure drops. This is the largest bore in the ASE range: at 0.5 MPa it delivers 3640.7 N of push force net of the spring (5211.5 N at 0.7 MPa), which works out to lifting roughly 185 kg vertically once you keep a 2:1 margin for the real part weight.
The body is a hard-anodized aluminium compact build to ISO 21287, with the bore roller-burnished for wear life and an S45C hard-chrome-plated rod. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 100 mm bore fits clamping stations and press fixtures where a full-length body would not. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the 1/4" port feeds a 0.2-1.0 MPa (28-145 psi) operating band.

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 | 3640.7 N |
| 0.7 MPa | 5211.5 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).

| S | Optional built-in magnet for CMSE / DMSE sensors (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
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.
The 3640.7 N net push at 0.5 MPa is enough to clamp heavy castings or weldments in a machining fixture, and the 10 mm stroke suits a quick-actuate clamp arm over a short gap.
Spring return pulls the ejector plate back automatically when air is lost, clearing the die area between cycles at 50-500 mm/s without a second valve port.
A 100 mm bore raises a heavy stop blade for pallet flow lanes; the compact body slots under the conveyor frame where a full-length ISO 15552 profile cylinder would not fit.
At this force class the ASE100X10 is the top of the range - the next size down, ASE80X25, pushes 2316.2 N at 0.5 MPa, so step up to the 100 mm bore when your clamp or eject needs more than that. Note the spring returns the rod to its retracted home on air loss; it will not hold a mid-stroke position, so add a stop or a powered return (the double-acting ACE series) if you need controlled positioning. Mounting brackets FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC bolt straight to the ISO 21287 face, and if you want position feedback, order the -S code so CMSE / DMSE switches can be used - without -S there is no magnet in the piston.
Quick checklist
It is a single acting push cylinder, spring return. Push force net of the return spring is 3640.7 N at 0.5 MPa and 5211.5 N at 0.7 MPa. Minimum working pressure is 0.2 MPa (needed to beat the spring), the band is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, speed 50-500 mm/s, and the 1/4" port takes air filtered to 40 um. In practice, plan on roughly 2184 N (about 222 kg of push) of usable work at 0.5 MPa.
The hard-anodized aluminium compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so the 100 mm bore fits tight fixtures and guards. The fixed TPU bumper at each end only decelerates the rod at the ends of travel - it never locks or holds a load. Mounting options are FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC, and the rod end is female M12x1.75. Position sensing needs the optional -S magnet code, which enables CMSE / DMSE switches.
