About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X15-10S
The ACEJ12X15-10S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 15 mm stroke by up to 10 mm on site, giving a usable range of 5-15 mm without changing the cylinder. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures where a full-length body cannot.
The hard-anodized aluminium body carries a 6 mm S45C hard-chrome rod with a female M3x0.5 thread, and the -S code on this model means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted directly in the body slots. A fixed TPU bumper at each end absorbs end-of-stroke impact, and the M5x0.8 ports suit small air lines.

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 (Ø12mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 kgf |
ACEJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X15-10S Is Used
Presence checking in tight test fixtures
With the fitted -S magnet driving CMSE or DMSE switches, the cylinder confirms a probe has fully seated inside a slim electronics test gantry where a full-length body would not fit.
Light hold-down on small assembly stations
About 34 N of usable force at 0.5 MPa holds small brackets or lens housings down during a screwdriving step, with the stop screw trimmed so the pad lands flush on each part.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X15-10S the Right Cylinder?
For light clamping and positioning in the 30-60 N class, the 12 mm bore is the right entry size: at 0.5 MPa it pushes 56.5 N, while the next size up, the 16 mm bore, reaches 100.5 N under the same pressure. If your load needs less than about 34 N of working force, this cylinder leaves margin at 0.5 MPa; step down is not available, as 12 mm is the smallest ACEJ bore. The -10 window suits applications where the final stroke is tuned during commissioning, such as seating a part against a fixture stop. Note the stop screw is a mechanical end stop only: on air loss the piston drifts, so it is not a mid-stroke lock. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet pairs with CMSE / DMSE switches for end-of-stroke sensing.
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 0.15 – 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 Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X15-10S FAQ
It is double acting with a 15 mm stroke adjustable down to 5 mm via the -10 stop screw, running at 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, with M5x0.8 ports and a female M3x0.5 rod thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits narrow jigs and guards. FA flange, LB foot and FTC brackets plus I and Y rod knuckles bolt to the standard face. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots for position signals. A fixed TPU bumper at each end absorbs end-of-stroke impact; the stop screw only shortens the extend stroke and does not hold a load on air loss.
