The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE32X10SB is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø32mm 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.
A single acting push cylinder with spring return, the ASE32X10SB extends its 12 mm rod with air and lets the return spring retract it, so one air line is all the plumbing needs. The 32 mm bore delivers 352.5 N of push at 0.5 MPa (513.4 N at 0.7 MPa), already net of the spring, and it starts moving from just 0.2 MPa. The 10 mm stroke suits short eject, clamp and present moves where travel is minimal.
The body is an ISO 21287 compact build: a hard-anodized aluminium barrel with an S45C hard-chrome-plated rod, saving about 50% of the mounting length of an ISO 15552 profile cylinder. A fixed TPU bumper absorbs end-of-stroke shock at both ends, and the optional -S magnet (fitted on this model) accepts CMSE / DMSE switches for end-of-stroke signalling. At 0.5 MPa the push equates to roughly 36 kgf, so plan on lifting about 18 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 | 352.5 N |
| 0.7 MPa | 513.4 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). |

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.
A 10 mm kick on a CNC jig pushes a machined housing off its locating pin between cycles; the spring retracts instantly when the 1/8" port vents.
Short-stroke clamping of a connector housing during a screwdriving step, with a CMSE switch on the -S magnet confirming full extension at 352.5 N push.
On a packaging machine, the compact body tucks into tight guarding to flip a flap or index a light box, then the spring pulls the rod home for the next carton.
At 352.5 N push at 0.5 MPa, this bore sits between the 25 mm (210.1 N) and 40 mm (556.8 N) single-acting sizes; step up to 40 mm if your load needs more margin, or down to 25 mm for lighter parts. Remember the spring retracts the rod on air loss, so it returns to the retracted home position rather than holding a mid-stroke load. The B code gives a male rod thread and the port is 1/8"; pair it with FA/FB flange, LB foot, CA/CB clevis, CR, SDB or FTC mounting on the ISO 21287 face.
Quick checklist
Push is 352.5 N at 0.5 MPa and 513.4 N at 0.7 MPa, both already net of the return spring. Minimum working pressure is 0.2 MPa (28 psi), the operating range is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, speed is 50-500 mm/s, and air must be filtered to 40 um. It is single acting push: air extends, the spring retracts.
The ISO 21287 compact build saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow jigs and guarded gantries. A fixed TPU bumper at each end absorbs end-of-stroke shock. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped to the body; models ordered without the -S code have no magnet.
