Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X35-30
The AirTAC ACEJ12 Adjustable Compact Cylinder ACEJ12X35-30 is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø12mm bore and 35mm stroke, M5×0.8 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.

About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X35-30
This compact ISO 21287 cylinder is double acting and carries an adjustable extend stroke: the -30 code gives a 30 mm stop-screw window, so the 35 mm stroke can be trimmed on site anywhere from 5 to 35 mm. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into slim fixtures a full-length body cannot reach.
The hard-anodized aluminium body pairs with an S45C hard-chrome rod, a fixed TPU bumper at each end absorbs end-of-stroke shock, and the rod ends in a female M3x0.5 thread. Note that this unit has no magnet fitted; the optional -S code is what enables CMSE / DMSE switch sensing.

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 ACEJ12X35-30 Is Used
Micro part clamping
Holds small electronics or watch components in a light-duty jig where the 30 mm trim window lets you dial the clamp point between 5 and 35 mm.
Compact ejection station
Pushes tiny stamped parts off a fixture with 56.5 N at 0.5 MPa; add the -S magnet code if CMSE or DMSE position switches are wanted.
Lab slide actuation
Moves a small tray or shutter 5-35 mm inside a benchtop tester, using the short ISO 21287 body to fit behind a narrow panel.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X35-30 the Right Cylinder?
The stop screw shortens the extend stroke only - it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. FA flange or LB foot mounts and I/Y rod knuckles bolt to the ISO 21287 face; order the -S code if CMSE / DMSE switches will be needed later.
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 ACEJ12X35-30 FAQ
It is double acting with a 30 mm adjustment window on the 35 mm extend stroke (usable 5-35 mm), runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, port M5x0.8, female M3x0.5 rod thread, PT ports.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight guards and gantries. Sensing is not included by default: order the optional -S magnet code to enable CMSE / DMSE reed or solid-state switches on the body slots. Mounting is via FA flange or LB foot plus I/Y rod knuckles, and a fixed TPU bumper at each end absorbs end-of-stroke impact.
